# Tetrachloro-1,1-difluoroethane

Tetrachloro-1,1-difluoroethane or 1,1,1,2-tetrachloro-2,2-difluoroethane, Freon 112a, R-112a, or CFC-112a is an asymmetric chlorofluorocarbon isomer of tetrachloro-1,1-difluoroethane with formula CClF$_2$CCl$_3$. It contains ethane substituted by four chlorine atoms and two fluorine atoms. With a boiling point of 91.5°C it is the freon with second highest boiling point.
Tetrachlorodifluoroethane as made is a mixture of the symmetrical and asymmetric isomers.

## Preparation

Tetrachloro-1,1-difluoroethane can be prepared in 40% yield by reacting 1,1,2-trichloro-1,2,2-trifluoroethane (freon 113) with aluminium chloride at 60°C.
It can also be made in a reaction with hydrogen fluoride with hexachloroethane or tetrachloroethane with extra chlorine. This reaction occurs with an aluminium fluoride catalyst at 400°C. unsymmetrical trichlorotrifluoroethane (CCl$_2$FCClF$_2$) is also produced along with other chlorofluorocarbons. Separation of the symmetrical and unsymmetrical isomer is difficult.

## Properties

Tetrachloro-1,1-difluoroethane is non-combustible.
It has a critical pressure of 4.83 MPa and a critical temperature of 279.2°. At the critical point the density is 0.754 g/cc.
Tetrachloro-1,1-difluoroethane in liquid form is miscible with perfluorocarbons.

### Reactions

Tetrachloro-1,1-difluoroethane reacts with zinc in ethanol at 60°C to yield unsymmetrical dichlorodifluoroethylene (CCl$_2$=CF$_2$).

## Uses

Tetrachlorodifluoroethane (CFC-112a), as with most high boiling point CFCs, has various uses as a non-flammable and clean agent solvent. It has historically been used as an extractant in liquid-liquid extraction and dry cleaning processes. CFC-112 and CFC-112a have also been used as feedstock chemicals in the manufacturing of fluorovinyl ethers. CFC-112a and its isomers are attractive organic solvents, as they have many important properties: they are nonflammable, clean drying, and have lower toxicity than common chlorinated organic solvents.
Tetrachlorodifluoroethane (mixture of isomers) has a niche application as a veterinary medicine to treat parasites (Fasciola hepatica).

## Atmosphere

Tetrachloro-1,1-difluoroethane was first detected in air collected from Cape Grim, Tasmania in the Cape Grim Air Archive, and later from air bubbles in snow from Greenland. The substance made its first appearance around 1965, and increased in level until around 2000. In 2000 Earth's atmosphere contained 0.08 parts per trillion of Freon 112a. Level slightly declined to 0.07 ppt by 2012. Estimated lifetime in the stratosphere is 44 years. By 2014 3,600 tons of Freon 112a had been put into the atmosphere. As of 2023, levels have been rising in the Earth's atmosphere.
As a greenhouse gas its radiative efficiency is 0.25 Wm$^{−2}$ppb$^{−1}$.
# Mercer County Airport (West Virginia)

Mercer County Airport (IATA: BLF, ICAO: KBLF, FAA LID: BLF) is in Mercer County, three miles northeast of Bluefield, West Virginia and about nine miles southwest of Princeton, West Virginia. The National Plan of Integrated Airport Systems for 2011–2015 categorized it as a general aviation facility.
The airport has been served by scheduled airlines. Service was subsidized by the Essential Air Service program until August 1, 2006, when it ended due to federal law not allowing a subsidy over $200 per passenger for communities within 210 miles of a large or medium hub airport (Charlotte/Douglas International Airport in North Carolina being 173 miles away). Federal Aviation Administration records say Mercer County Airport had 2,041 passenger boardings (enplanements) in calendar year 2004, 1,885 enplanments in 2005, 1,833 in 2006 and 1,721 in 2007. Scheduled passenger flights ended in 2007.

## Facilities

Mercer County Airport covers 511 acres (207 ha) at an elevation of 2,857 feet (871 m). Its one runway, 5/23, is 4,743 by 100 feet (1,446 x 30 m) asphalt.
In the year ending July 11, 2023, the airport had 16,400 aircraft operations, average 45 per day: 88% general aviation, 11% air taxi, and <1% military. 21 aircraft were then based at this airport: 15 single-engine, 5 helicopter, and 1 ultralight.

## Former airlines

* Piedmont Airlines 1953–54 to 1980 (the airport opened about 1953)

The cemetery was listed on the National Register of Historic Places in 2014.
# Public opinion brigades

The public opinion brigades (Vietnamese:Dư luận viên) is a state-sponsored web brigade of the Communist Party of Vietnam or linked to the Communist Government of Vietnam.
Similar to Russia's web brigades and China's 50 Cent Army, participants report that they are organized into teams and groups of commentators that participate in Vietnamese and international political blogs and Internet forums using sockpuppets and large-scale orchestrated trolling and disinformation campaigns to promote pro-Vietnamese communist propaganda.

## Background

It is unclear how the brigades started since the Communist Party of Vietnam (CPVN) often controls political information. However, the earliest form of Internet propaganda supporting CPVN seems to have begun in 2007, when the Government announced to "eliminate any wrong news that threaten the Party's rule". As the Communist Party is the only party allowed by Vietnamese constitution, it was the beginning of the brigades. In 2017, Lieutenant-General Nguyen Trong Nghia, deputy head of the Vietnamese military's political department, confirmed that Vietnam has a new, 10,000-strong military cyber warfare unit to counter criticisms of the government on the Internet. The cyber unit named Force 47 is active in several sectors.

## Force 47

Force 47 (Lực lượng 47) is a large cyberspace military unit of Vietnam revealed in December 2017 with a focus on combating "wrong views" on the Internet. Internet security firms such as Volexity and FireEye report pro-Hanoi or Hanoi regime-sponsored hackers installed spyware on anti-government, dissident websites to track who visits them.

## Methods

The methods used are not always clear, but includes criticism of opposing views to those of the Communist Party. Vietnamese nationalists, dissidents and anti-communists claim that the CPVN has been doing this for a long time, to brainwash people's minds and distort and truth, branding who disagree with the Communist Party as "traitors of the nation".
BBC and Deutsche Welle correspondents have also reported about the brigades' activities. Other Governments also accused Vietnamese Communist Party's troll army for attacking and hacking websites that criticize the CPVN.

### Distortion of history

The CPVN has attempted to rewrite history, including war crimes by North Vietnam and the Viet Cong during the Vietnam War having been completely erased to serve the Party's agenda, promoting only themselves as the "heroes" of Vietnam.

# Ray Jackson (basketball)

Ray Jackson (born November 13, 1973) is an American former professional basketball player. He is most well known for his time as a member of the Fab Five with the Michigan Wolverines.

## College career

Jackson was part of the famed University of Michigan Wolverines Fab Five along with former NBA players Chris Webber, Jimmy King, Jalen Rose, and Juwan Howard that reached the 1992 & 1993 NCAA Men's Division I Basketball Championship games as both Freshmen and Sophomores.
Although the Fab Five final four appearances have been forfeited, he was not among the players called before the grand jury (Robert Traylor, Webber, Rose, Maurice Taylor and Louis Bullock) in the University of Michigan basketball scandal and was not found to have received large amounts of money.
Jackson and King were the only two members of the Fab Five to stay at Michigan for their full four years of eligibility; Webber left after his sophomore year and Rose and Howard after their junior years. Jackson's best season at Michigan came in his senior year, as he averaged a team-high of nearly 16 points per game.

## Professional career

Known for his time as one member of the Fab Five, Jackson was not drafted by an NBA team and never played in the league. He was cut in preseason by the New York Knicks before the 1995–96 season and cut by the Detroit Pistons before the 1996–97 season. He was drafted in the Continental Basketball Association (CBA) by the Grand Rapids Hoops #35 in the 3rd round in 1995.
While with the Hoops, he won the 1995–96 CBA Rookie of the Year Award.
He then played in France with Pro A team SIG Basket, in Argentina in the Liga Nacional de Básquet with Obras Sanitarias (where he averaged 16 points per game) and Venezuela with Cocodrilos de Caracas.
In a February 10, 2007 article on Yahoo Sports, Jackson says that: "It took me a long time to get over the fact that I was the only one that didn't make it to the NBA from the Fab Five, but I'm over it because I'm back home and I'm happy with what I'm doing with my life."

## Post-basketball career

Jackson lives in Austin, Texas, where he runs a moving company and Rise Up, a not-for-profit organization that assists children socially, educationally and on the basketball court.
# Third Saudi State

The Third Saudi state is the heir to the two earlier Saudi states: the first and the second, founded by Abdul Aziz bin Abdul Rahman (also known as "Ibn Saud"), who managed to capture the city of Riyadh on January 13, 1902. A long series of conflicts and conquests ultimately led to the establishment of the modern and contemporary Saudi state, the Kingdom of Saudi Arabia.

## History

The third Saudi state was known at the beginning of its reign as "the Emirate of Riyadh" (1902–1913) and "the Emirate of Nejd and Hasa" (1913–1921). After the overthrow of the rival Emirate of Ha'il gave the Emirate of Najd and Al-Ahsa control of the entire Nejd region, it became known as the Sultanate of Nejd. Abdul Aziz conquered the Kingdom of Hejaz in 1925. He raised Nejd to a kingdom in 1927, and his dominions became known as the Kingdom of Hejaz and Nejd and its annexes. Abdul Aziz administered the two portions of his dual kingdom separately until the annexation of the Southern Territory and the announcement of the establishment of the Kingdom of Saudi Arabia in 1932.
# Michigan World War II Army Airfields

During World War II, the United States Army Air Forces (USAAF) established numerous airfields in Michigan for training pilots and aircrews of USAAF fighters and bombers.
Most of these airfields were under the command of First Air Force or the Army Air Forces Training Command (AAFTC) (a predecessor of the current-day United States Air Force Air Education and Training Command). Other USAAF support commands (Air Technical Service Command (ATSC); Air Transport Command (ATC) or Troop Carrier Command) commanded a significant number of airfields in support roles.
Remnants of these wartime airfields exist. Many were converted into municipal airports, some were returned to agriculture, and several were retained as United States Air Force installations and were front-line bases during the Cold War. Hundreds of the temporary buildings that were used survive today, and are being used for other purposes.
