| titleOfInvention | Process for producing composite mixed ester |
| abstract | This invention discloses a process for producing a composite mixed ester suitable for use as a plasticizer having improved nonvolatility as compared with dibasic acid diesters which have excellent general-purpose plasticizer properties and have been used in a large amount but have come to be regarded as endocrine disruptors. The mixed ester is equal to the dibasic acid diesters in production cost and performance even when it contains none of these diesters. Also provided is a composition. Dibasic-acid diesters volatilize according to their vapor pressures, while polymers have nonvolatility and reduced toxicity according to their molecular weights. However, polymers have poor plasticizer performance. Although composite esters having an intermediate molecular weight may meet the requirement, they are difficult to produce and have poor profitability. The process comprises subjecting acids, a diol, and a terminal alcohol to dehydrating esterification and subsequently subjecting the excess alcohol to transesterification. Thus, a composite mixed ester is advantageously produced, which is a composition represented by (R(PX)1-2(AX)n-1AR) and which contains residues of the two dibasic acids bonded in such a manner that one or two residues of one of the acids and one or two residues of the other occur alternately. |
