FIELD: chemistry.
SUBSTANCE: invention relates to a method of purifying organoaluminium compounds (OAC), which includes a step for sedimentation of OAC with separation of a clarified stream and a stream with high content of sludge and a step of filtering the clarified stream on the ceramic membrane, to obtain a purified OAC, where the retentate recycle stream passes through a heat exchanger to stabilize the temperature of the stream.
EFFECT: invention enables to obtain highly purified and highly efficient OAC with sludge content of less than 0.1% by weight, eliminates energy-intensive purification steps and reduces consumption of aluminum and olefin in the process of producing OAC.
