Title:
METHOD FOR PRODUCING ARYLOXY TITANIUM COMPOSITION, AND ARYLOXY TITANIUM COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2011/105439
Kind Code:
A1
Abstract:
Disclosed is a method for producing an aryloxy titanium composition, which is extremely favorable as a catalyst for use in the production of a diaryl carbonate, and with which problems such as obstruction of storage tanks, pipes, pumps, and the like during storage or transfer, and a decrease in catalytic activity caused during long-term storage can be solved. The method for producing an aryloxy titanium composition comprises a step (1) in which a diaryl carbonate is added to an organooxy titanium composition having an R-O-Ti bond (wherein R represents an organic group containing 1 to 20 carbon atoms), components having a boiling point lower than the diaryl carbonate are distilled off along with the diaryl carbonate, thereby obtaining an aryloxy titanium composition.
