The invention discloses a process method for processing isopropenyl acetate absorption liquid, which comprises the following steps that: 10 DEG C to 90 DEG C isopropenyl acetate absorption liquid is fed into a film evaporator, the film evaporation is carried out at the temperature being 40 DEG C to 200 DEG C, the vacuum degree being 0.001MPa to 0.099MPa and the rotating speed being 10r/min to 800r/min, substances such as acetone, isopropenyl acetate and the like are collected, and then, the residue liquid is subjected to continuous material discharging. The process method has the advantages that the extraction rate of the isopropenyl acetate is high, thermal sensitive substances in the absorption liquid can not easily generate decomposition or polymerization reaction, in addition, the residue liquid quantity is small, the liquid state material discharging can be ensured, the coking in the evaporator can not be caused, the work intensity is reduced, and the on-site environment is improved.
