Steglich esterification - Wikipedia

The Steglich esterification is a variation of an esterfication with dicyclohexylcarbodiimide as a coupling reagent and 4-dimethylaminopyridine as a catalyst.The reaction was first described by Wolfgang Steglich in 1978. It is an adaptation of an older method for the formation of amides by means of DCC (dicyclohexylcarbodiimide) and 1-hydroxybenzotriazole (HOBT).

Esterification - Acid, Esters, Reaction, and Acetic .

The continuous esterification process is used industrially to make methyl acetate from acetic acid and methanol and ethyl acetate from acetic acid and ethanol. The alternative process of making esters from the reaction of an alcohol with an anhydride is important in the manufacture of drugs. This reaction gives an acid as a by-product.
