2-Acetylpyridine is an organic compound with the formula CH3COC5H4N.
 It is a viscous colorless liquid that is widely used as a flavoring substance.
 It is found in malt and produced by the Maillard reaction and by nixtamalization.
 It contributes to the flavor of corn tortillas, popcorn, and beer.
Sulfur mustard, commonly known as mustard gas, is the prototypical substance of the sulfur-based family of cytotoxic and vesicant chemical warfare agents known as the sulfur mustards which have the ability to form large blisters on exposed skin and in the lungs.
 They have a long history of use as a blister-agent in warfare and along with organoarsenic compounds are the most well-studied such agents.
 Related chemical compounds with similar chemical structure and similar properties form a class of compounds known collectively as sulfur mustards or mustard agents.
 Pure sulfur mustards are colorless, viscous liquids at room temperature.
 When used in impure form, such as warfare agents, they are usually yellow-brown and have an odor resembling mustard plants, garlic, or horseradish, hence the name.
 The common name of "mustard gas" is considered inaccurate because the sulfur mustard is not actually vaporized, but dispersed as a fine mist of liquid droplets.
 Sulfur mustard was originally assigned the name LOST, after the scientists Wilhelm Lommel and Wilhelm Steinkopf, who developed a method of large-scale production for the Imperial German Army in 1916.
Methyl 2-chloroacrylate is a colorless liquid used in manufacture of acrylic high polymer similar to polymethylmethacrylate.
 It is also used as a monomer for certain specialty polymers.
Napalm is a flammable liquid used in warfare.
 It is a mixture of a gelling agent and either gasoline (petrol) or a similar fuel.
 It was initially used as an incendiary device against buildings and later primarily as an anti-personnel weapon, as it sticks to skin and causes severe burns when on fire.
 Napalm was developed in 1942 in a secret laboratory at Harvard University, by a team led by chemist Louis Fieser.
 Its first recorded use was in the European theatre of war during World War II.
 It was used extensively by the US in incendiary attacks on Japanese cities in World War II as well as during the Korean War and Vietnam War.
Silly Putty is a toy based on silicone polymers that have unusual physical properties.
 It bounces, but it breaks when given a sharp blow, and it can also flow like a liquid.
 It contains a viscoelastic liquid silicone, a type of non-Newtonian fluid, which makes it act as a viscous liquid over a long time period but as an elastic solid over a short time period.
 It was originally created during research into potential rubber substitutes for use by the United States in World War II.
Chloromethyl chloroformate (CClOCHCl) is a chemical compound developed for use in chemical warfare in World War I.
 It is a tearing agent designed to cause temporary blindness.
 It is a colorless liquid with a penetrating, irritating odor.
Dioctyl terephthalate (bis(2-ethylhexyl) benzene-1,4-dicarboxylate or Di(2-ethylhexyl) terephthalate), commonly abbreviated DOTP or DEHT, is an organic compound with the formula CH(COCH).
 It is a non-phthalate plasticizer, being the diester of terephthalic acid and the branched-chain 2-ethylhexanol.
 This colorless viscous liquid used for softening PVC plastics is known for chemical similarity to general purpose phthalates such as DEHP and DINP, but without any negative regulatory pressure.
 It possesses very good plasticizing properties and may be used as a direct replacement for DEHP and DINP in many applications.
1,2,4-Trichlorobenzene is an organochlorine compound, one of three isomers of trichlorobenzene.
 It is a derivative of benzene with three chloride substituents.
 It is a colorless liquid used as a solvent for a variety of compounds and materials.
Frances Mary Gore Micklethwait (1867– 25 March 1950), was an English research chemist, among the first to study and seek an antidote to mustard gas during the First World War.
 She received an MBE for her top secret wartime work, which has since come to light.
The T1 tanker or T1 are a class of sea worthy small tanker ships used to transport fuel oil before and during World War II, Korean War and Vietnam War.
 The T1 tanker classification is still in use today.
 T1 tankers are about 200 to 250 feet in length and are able to sustain a top speed of about 12 knots.
 The hull designation "AO" is used by the US Navy to denote the ship is a T1 oil tanker and "AOG" that the T1 is a gasoline tanker.
 The small size allows the T1 to enter just about any sea port or to anchor around a small island, this was very useful during the Pacific War.
 The T1 tanker can carry about 48,000 to 280,000 BBLs.
 Some T1 tankers were used to transport goods other than oil, a few were used for black oil-crude oil, diesel, chemicals and rarely bulk cargo like grain.
 T1 tankers are also called liquid cargo carriers.
 The T1 tanker has about a 6,000 to 35,000 DWT of cargo.
 The small size also gives the ships short turn around time for repair, cleaning, loading and unloading.
 A T1 tanker carrying dirty cargo, like crude oil needs a few weeks of labor to clean before carrying clean cargo.
 Most T1 ships during World War II were named after major oil fields. T1 tanker are operated by the US Navy, War Shipping Administration and United States Maritime Commission.
 Some T1 were loaned to England in the Lend-Lease program for World War II, after the war most were returned to the USA.
 After World War II many of the T1 ships were sold to for civilian use.
 Each T1 had emergency life rafts on the boat deck.
 The ships had cargo booms and piping to load and unload fuel.
 During war time the T1 are armed for protection with deck guns.
 A typical ship may have one single 3"/50 dual purpose gun, two 40 mm guns and three single Oerlikon 20 mm cannon.
 A T1 at war time normally had a crew of 38 and up to 130.
 If operating as a United States Merchant Marine ship, the crew would be a mix of civilian Merchant Marines and United States Navy Armed Guards to man the guns.
