摘要

A mixture of isomeric decyl benzoate esters (I) containing (A) 50-99 % 2-propylheptyl benzoate and (B) 1-50 % 2-isopropyl-4-methylhexyl and/or 2-isopropyl-5-methylhexyl and/or 2-propyl-4-methylhexyl and/or 2-propyl-5-methylhexyl benzoate. Independent claims are also included for (1) mixtures containing 5-90 wt% (I) and 10-95 wt.% di-(4-13C alkyl) phthalate or 10-95 wt.% di-(4-13C alkyl) adipate or 10-95 wt.% di-(4-13C alkyl) cyclohexanedicarboxylate (2) methods for the production of (I) from the corresponding (iso)propylheptanols and/or (iso)propyl-methylhexanols by esterification with benzoic acid or by transesterification with methyl, ethyl, propyl or butyl benzoate
