Nonvolatilealpha-branched-chain fatty esters
Tóm tắt
Nonvolatilealpha-branched carboxylic acids and esters have been prepared by a free radical reaction. Various esters of the reaction products of hexadecanoic and octadecanoic acids with the terminal olefins, octene, decene, and dodecene have been synthesized. Fractional crystallization from acetone is a useful method for preparing these compounds in a highly purified state. Mass spectra confirm that branching is found exclusively at thealpha- or 2-position.
