(The production mannered null alcohols of meta)

摘要

Tetra- alkoxy titanium is removed from reaction system easily, the waste water does not come out, (production method of meta) acrylic acid ester is offered. Alcohol (meta) acrylate after pointing to the transesterification under existing of tetra- alkoxy titanium, adding the water of 4 - 35 time weight vis-a-vis tetra- alkoxy titanium, adding water disassembling tetra- alkoxy titanium under 50 - the 80C, to insoluble it converts, it features that it separates removes the water and the insoluble component, (production method of meta) acrylic acid ester.
