PRODUCTION OF TEREPHTHALIC ACID DI-ESTERS USING ALCOHOL-AMINE PROMOTERS
摘要
<p>The invention is directed to a process for preparing a terephthalic acid di-ester. The process includes contacting terephthalic acid with a C6-C10 alcohol in the presence of an organo-titanium catalyst and an alcohol-amine promoter under conditions effective to form a corresponding terephthalic acid di-ester. The promoter can improve the reaction time by as much as 50%.</p>
