Abstract
The invention provides a microencapsulated Lewis acid characterized in that a Lewis acid is supported through coordinate bonds on microcapsules formed of an organic polymer as a novel Lewis acid supported on a polymer in order to overcome the technical limit of conventional catalysts supported on polymers and in addition, to solve problems attendant upon the preparation of a reaction system and separation and recovery from reaction products about Lewis acid catalysts having great industrial usefulness.
Claims8
A microencapsulated Lewis acid characterized in that a Lewis acid is supported through coordinate bonds on microcapsules formed of a substantially non-crosslinked polymer formed by addition polymerization.
A Lewis acid supported through coordinate bonds on a substantially non-crosslinked polymer which contains aromatic rings on side chains.
A process for preparing a microencapsulated Lewis acid which comprises supporting a Lewis acid through coordinate bonds on microcapsules on formation of the microcapsules from substantially non-crosslinked polymer by a microencapsulation process.
