エステル化反応とトランスエステル化反応に触媒作用を及ぼすための錯体触媒およびそれを用いたエステル化/トランスエステル化プロセス

Document Type and Number:

Japanese Patent JP4693419

Kind Code:

B2

Abstract:

The present invention relates to a novel catalyst complex for catalysing esterification and trans-esterification reactions, comprising: (i) a polymeric titanium glycolate having the formula [T_iO₄(CH₂)₄]_nwherein n=1 to 200; and (ii) an alkali metal glycolate; wherein the molar ratio of the polymeric titanium glycolate and the alkali metal glycolate is about 1.25:1 to about 100:1, preferably about 1.25:1 to about 10:1; and to a process for esterification of a dicarboxylic acid compound and an dialcoholic compound, followed by polycondensation to form a polyester.
