| titleOfInvention | Polycondensation catalyst for producing polyester and method of producing polyester using polycondensation catalyst |
| abstract | FIELD: chemistry. n SUBSTANCE: invention relates to a polycondensation catalyst for producing polyester via an esterification or transesterification reaction between a dicarboxylic acid or ester-forming derivative thereof and glycol. The catalyst contains solid base particles coated with a layer of titanic acid in amount of 0.1-50 pts. wt in terms of TiO 2 , per 100 pts. wt of the solid base. The solid base is magnesium hydroxide or hydrotalcite. Solid base particles have on their surface an inner coating layer or an oxide layer of at least one element selected from silicon, aluminium or zirconium, or a composite oxide of at least two elements selected from silicon, aluminium and zirconium, in amount of 1-20 pts. wt per 100 pts. wt of the solid base. The outer coating layer consists of titanic acid in amount of 0.1-50 pts. wt of TiO 2 per 100 pts. wt of the solid base. Described also is a method of producing said catalyst and a method of producing an ester in the presence of said catalyst. n EFFECT: invention enables to obtain a catalyst with high catalytic activity, which is suitable for producing an ester with excellent colour and transparency. n 9 cl, 2 tbl, 74 ex |
