Title:
METHOD FOR PRODUCING N-METHACRYLOYL-4-CYANO-3-TRIFLUOROMETHYLANILINE
Document Type and Number:
WIPO Patent Application WO/2009/034936
Kind Code:
A1
Abstract:
Disclosed is a method for producing N-methacryloyl-4-cyano-3-trifluoromethylaniline,
wherein 4-cyano-3-trifluoromethylaniline is crystallized from a solvent
mixture of methanol and water, and the thus-obtained 4-cyano-3-trifluoromethylaniline
is reacted with methacrylic acid chloride. This production method enables
to improve liquid separation failure even in large-scale commercial production.
