摘要：NOVELTY - Processing isopropenyl acetate absorption liquid comprises feeding isopropenyl acetate absorption liquid at 10-90 degrees C to thin film evaporator at 40-200 degrees C under 0.001-0.099 MPa, performing thin film evaporation at 10-800 revolutions/minute, collecting substances comprising acetone and isopropenyl acetate, and discharging residual liquid continuously. USE - Method for processing isopropenyl acetate absorption liquid (claimed). ADVANTAGE - The method has high isopropenyl acetate extraction rate, and does not easily decompose or polymerize thermosensitive substance in the absorption liquid.
