SCALE-UP PROCESS OF BIFUNCTIONALIZED TRIBLOCK COPOLYMERS WITH SECONDARY AND TERTIARY AMINES, WITH APPLICATION IN DEWATERING AND DESALTING OF HEAVY CRUDE OILS.

摘要

The present invention consists in the development of chemical synthesis process to carry out the functionalization of monodispersed triblock copolymer (POE w-POP y-POE w) with secondary or tertiary amines at semi-industrial level in glass reactors with capacity between 1 L and 100 L. The process consists of two stages, the first one is employed alkylsulfonyl or arylsulfonyl chloride to obtain better leaving groups, whereas in the second stage is carried out over them the nucleophillic substitution with secondary or tertiary amines, to obtain the bifunctionalized triblock copolymers. The main advantage for this process is to reduce the quantity of unitary process done in each stage, furthermore the optimization of reaction times and the stoichiometric relationships.
