  • Patent number: 10125226
    Abstract: 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.

  • Patent number: 9366387
    Abstract: A process allows working with viscous petroleum referred to as “heavy and extra heavy crudes” such as 20 to 6° API by adding an appropriate biosurfactant to an aqueous phase containing a biosurfactant active compound. The surfactant can be alkyl glycosides, glycerol esters and alkyl betaines. The result is the formation of a stable crude/water emulsion even with salt present therein.
