ALCOHOL MIXTURE FOR PLASTICIZER

摘要

A C9 alcohol mixture for plasticizer obtained by the hydroformylation and hydrogenation of a C8 olefin mixture as the starting material obtained by the dimerization of a butene fraction, said alcohol mixture comprising from 8 to 50% by weight of a first group component having a retention time not longer than the retention time of isobutyl n-caprylate, from 8 to 40% by weight of a second group component having a retention time longer than that of isobutyl n-caprylate and not longer than that of methyl n-caprate and from 20 to 80% by weight of a third group component having a retention time longer than that of methyl n-caprate, as divided into such three components by gas chromatography using a capillary column packed with a polyethylene glycol having a number average molecular weight of 15,000 to 20,000 as an isomer separating agent.
