Toward more cost-effective production of biofuels from plant lignocellulosic biomass
In 1925, Henry Ford observed that fuel is present in all vegetative matter that can be fermented and predicted that Americans would some day grow their own fuel. Last year, global biofuel production reached ...

Acetylation
Acetylation (or in IUPAC nomenclature ethanoylation) describes a reaction that introduces an acetyl functional group into a chemical compound. (Deacetylation is the removal of the acetyl group.)
Specifically, acetylation refers to that process of introducing an acetyl group (resulting in an acetoxy group) into a compound, to be specific, the substitution of an acetyl group for an active hydrogen atom. A reaction involving the replacement of the hydrogen atom of a hydroxyl group with an acetyl group (CH3 CO) yields a specific ester, the acetate. Acetic anhydride is commonly used as an acetylating agent reacting with free hydroxyl groups. For example, it is used in the synthesis of aspirin and heroin.
