Abstract

PURPOSE: To obtain a dialkyl carbonate ecconomically, by subjecting an alkylene carbonate and an alcohol to ester exchange reaction in the presence of a quaternary phosphonium salt as a catalyst.
CONSTITUTION: An alkylene carbonate is reacted with an alcohol to give a dialkyl carbonate. A quaternary phosphonium salt shown by the formula (R1-R4 are alkyl, alkenyl, or aryl; X is I, Br, or Cl) is used as a catalyst for ester exchange reaction. Its amount is 0.001W1mol%, preferably 0.01W0.1mol% based on the alkylene carbonate of the raw material. The reaction temperature is 40W180°C, preferably 100W 150°C.
