Title:
(METH)ACRYLATE MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2016/163208
Kind Code:
A1
Abstract:
The present invention provides a (meth)acrylate manufacturing method characterized in that when manufacturing a (meth)acrylate by an ester exchange reaction between an alcohol and a monofunctional (meth)acrylate using catalyst A and catalyst B together, contact treatment of the ester exchange reaction product with adsorbent C is performed.
Catalyst A: One or more kinds of compounds selected from a group consisting of cyclic tertiary amines with an azabicyclo structure and salts or complexes thereof, amidine and salts or complexes thereof, compounds with a pyridine ring and salts or complexes thereof, phosphine and salts or complexes thereof, and compounds with a tertiary diamine structure and salts or complexes thereof.
Catalyst B: One or more kinds of compounds selected from a group consisting of compounds comprising zinc.
Adsorbent C: One or more kinds of compounds selected from a group consisting of oxides and hydroxides comprising at least one of magnesium, aluminum and silicon.
