Title:
PROCESS FOR PRODUCING PRODUCT OF DECOMPOSITION OF FLUORINATED ESTER COMPOUND
Document Type and Number:
WIPO Patent Application WO/2002/048085
Kind Code:
A1
Abstract:
A process for production with high productivity which comprises efficiently decomposing a fluorinated ester compound at a low temperature and a high reaction rate. In the process, a fluorinated ester compound having a decomposable ester bond is decomposed at the ester bond to obtain a decomposition product. The ester bond decomposition reaction is conducted in the presence of KF at a temperature of 200°C or lower substantially without using a solvent. The reaction is conducted while continuously supplying the fluorinated ester compound to the reaction zone and continuously discharging the decomposition products from the reaction zone.
