Petroleum
* Most petroleum is found in the Middle East , North America , and Russia
  - removed from the earth as a liquid called crude oil
* Most petroleum produces compounds
  - toxic compounds
* Some petroleum is located offshore.
* accounts for more than half of export revenues.
* based fuel finite resource
  - paints Low toxicity
* can also contain molecules containing oxygen, nitrogen, sulfur, and metals.
* comes from under the ground.
* commodity-driven product.
* complex liquid mixture that contains hundreds of compounds
  - mixture of hydrocarbons
* complicated mix of compounds.
* contains hydrocarbons.
* dissolves the protective waxes in bird feathers.
* fossil fuel that occurs naturally in deposits, usually underground
* has a chronic diarrhoea, but only in the daytime
  - many thioethers in it as well
  - potency
  - roughly two atoms of hydrogen for every atom of carbon
* includes atoms.
* includes chemical chain
  - groups
* is Colombia's most important revenue source
  - Ecuador's chief export
  - also a resource that is very important to Venezuela's economy
  - an oily, liquid mixture of hydrocarbons found in scattered subterranean deposits
  - called a nonrenewable energy source because it takes millions of years to form
  - capital intensive and pollutes
  - considered as the basic material for production of plastics
  - derived from the fossil remains of marine creatures
* is formed by the slow alteration of organic remains over time
  - within the crust of the earth
  - generated by heating organic matter deposited within marine sediments
  - heated at very high temperatures to be broken down into polymers and made into plastic
  - like blood, running everywhere throughout the body of the earth
  - natural product from the earth
* is one of Oklahoma's greatest resources
  - the most exciting sectors of the economy
  - part of asphalt
  - poisonous for the Earth s climate and it has been the cause of so much human suffering
  - produced from wells in large quantities
  - pumped from deep in the earth
  - removed from oil traps by drilling
  - required to run our automobiles, trains, and aircraft
  - shipped around the world in boats
  - synonymous with energy
  - taken by trucks, railroads, ships, or pipelines to places called refineries
* is the basis for a majority of the materials used for surfboards
  - chief mineral, and sago, pepper, and rubber are important commercial crops
  - dominant fuel used in Washington State
  - fossil remains of planktonic algae
* is the major mineral export
  - product, followed by lignite, pyrites, fluorspar and barytes
  - source of plastics, but coal and cellulose are other raw materials
* is the most important mineral resource of the Pacific
  - significant mineral of the area, extracted primarily on the Persian Gulf
  - valuable mineral
  - oily stuff petrol is made out of
  - remains of former plants
  - single largest source of energy for the United States
  - transported by underwater pipelines to storage tanks on shore
  - trapped by underground rock formations
  - unrefined oil
* is used as the feedstock for the polystyrene
  - for many things including gasoline, kerosene, heating oils, and other fuels
  - only to power long-distance aeroplanes
  - very versatile and can be changed into different forms for different purposes
* jelly keeps the blister moist to help prevent further irritation.
* liquid fossil fuel.
* minor source of oil in the Bahamas.
* mixture of many different chemical substances
  - larger hydrocarbons that are normally liquids
  - oil and coal
  - several compounds of carbon and is found deep within the earth s crust
* non-renewable resource that primary cause of climate change.
* occurs in the pores between sand grains and porous sandstones are excellent reservoirs
  - most irregularly, both geographically and geologically
* plays a central role in world energy supplies and markets.
  - small vesicles which itch, sting and burn
* product used as a solvent in many household cleaners among other products.
* regulated substance.
* requires the drilling of oilwells and pumping the crude oil.
* solvent that can weaken leather structure over time.
* still plays a role, especially with the burgeoning petrochemical industry.
+ Refining, Petroleum: Industries
  * Petroleum contains hydrocarbons. After distillation, it still contains chemical compounds with sulfur, oxygen and  Nitrogen as well as other unwanted compounds, such as Alkalenes. For this reason, they are extracted using a process called hydrogenation. In hydrogenation, Hydrogen sulfide and ammonia gases are produced. These gases require special handling, as they are very toxic.
+ Thioether: Functional groups :: Organosulfur compounds
  * Thioethers are important in biology. They are present in some amino acids. Petroleum has many thioethers in it as well. Thioethers can be made in the laboratory by the reaction of a thiol with a base and an electrophile. They can do many interesting reactions. It is easy to oxidise them to sulfoxides and then sulfones.
  * Petroleum', also called 'crude oil', is a thick and black liquid. It is a natural mineral as is mainly made of hydrocarbons. Most petroleum is found in the Middle East, North America, and Russia. It is the most important world fuel source.
