Title:
METHOD FOR PRODUCING (METH)ACRYLATE DERIVATIVE HAVING ISOCYANATE GROUP
Document Type and Number:
WIPO Patent Application WO2005092842
Kind Code:
A8
Abstract:
The invention aims to provide a method whereby (meth)acrylate derivatives having an isocyanate group can be obtained in high yield by dehydrochlorination of 3-chloropropionate derivatives having an isocyanate group under industrially advantageous and mild conditions, and the content of residual hydrolyzable chlorine can be reduced. A method for producing a (meth)acrylate derivative having an isocyanate group comprises performing dehydrochlorination of a 3-chloropropionate derivative having an isocyanate group in the presence of a basic nitrogen compound having a tertiary nitrogen, the tertiary nitrogen of the basic nitrogen compound having at least one group other than an aromatic ring group.
