Ethanol and isopropyl are types of what?
Isopropyl alcohol is also known as 2-propanol, "sec"-propyl alcohol, IPA, or isopropanol. IUPAC considers isopropanol to be an incorrect name as the hydrocarbon isopropane does not exist. Isopropyl alcohol is miscible in water, ethanol, ether, and chloroform. It will dissolve ethyl cellulose, polyvinyl butyral, many oils, alkaloids, gums and natural resins. Unlike ethanol or methanol, isopropyl alcohol is not miscible with salt solutions and can be separated from aqueous solutions by adding a salt such as sodium chloride. The process is colloquially called "salting out", and causes concentrated isopropyl alcohol to separate into a distinct layer. Isopropyl alcohol forms an azeotrope with
Corn ethanol Corn ethanol Corn ethanol is ethanol produced from corn biomass and is the main source of ethanol fuel in the United States. Corn ethanol is produced by ethanol fermentation and distillation. Corn ethanol results in lower greenhouse gas emissions than gasoline and is fully biodegradable, but environmental concerns ; approximately 40.5% of the U.S. corn croplands are used for ethanol production. Corn ethanol is mainly added as an oxygenate to gasoline to produce a low-level blend used in motor vehicles. To a lesser extent, it is used as fuel for E85 flex-fuel vehicles. There are two main types of corn
