Esterification Process |
| abstract |
A process for the preparation of an ester comprises carrying out an esterification in the presence of a catalyst comprising the reaction product of an orthoester or a condensed orthoester of titanium or zirconium, an alcohol containing at least two hydroxyl groups, a 2-hydroxy acid and a base. The process can be a direct esterification or a transesterification and can be a polyesterification. The catalyst can effectively produce esters without leading to a haze in the final product and there is a reduced amount of yellowing of polyesters in comparison to known catalysts. |
