  The present invention is related to formulations consisting of block copolymers α,ω-di-aryl or alkyl sulfonates of poly(ethylene oxide)w-poly(propylene oxide)-poly(ethylene oxide)w of bis-ammonium and block copolymers α,ω-di-amine of poly(ethylene oxide)w-poly(propylene oxide)-poly(ethylene oxide)w, that are effective in the dewatering and desalting crude whose specific gravities are within the range of 14 to 23°API.

  本发明涉及由聚(环氧乙烷)w-聚(环氧丙烷)-聚(环氧乙烷)w 的双铵嵌段共聚物α,ω-二芳基或烷基磺酸盐和聚(环氧乙烷)w-聚(环氧丙烷)-聚(环氧乙烷)w 的嵌段共聚物α,ω-二胺组成的制剂，这些制剂可有效地对比重在 14 至 23°API 范围内的原油进行脱水和脱盐。

  A chemical synthesis process is provided for the functionalization of monodispersed triblock copolymer (POEw-POPy-POEw) with secondary or tertiary amines at a semi-industrial level in glass reactors having a capacity between 1 L and 100 L. The process includes two stages where the first stage uses an alkylsulfonyl or arylsulfonyl chloride to obtain better leaving groups, and the second stage is the nucleophilic 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, the optimization of reaction times, and the stoichiometric relationships.

  该工艺包括两个阶段，第一阶段使用烷基磺酰氯或芳基磺酰氯获得更好的离去基团，第二阶段使用仲胺或叔胺进行亲核取代，从而获得双官能化的三嵌段共聚物。这种工艺的主要优点是减少了每个阶段的单一过程，优化了反应时间和化学计量关系。
