2-메틸펜탄산 C화학적 특성, 용도, 생산
개요
2-Methylvaleric acid has a powerful, pungent, acrid odor. Below 10 ppm the flavor is agreeable, sour, and oily. At higher concentrations, the flavor is too acidic. May be prepared by catalytic oxidation of 2-methyl pentanealdehyde; from 2-chloropentane with sodium and C02 under pressure; by decarboxylation of methyl propyl malonic acid; two optically active iosmers are known.화학적 성질
