Synthesis and surface activity study of novel branched zwitterionic heterogemini fluorosurfactants with CF3CF2CF2C(CF3)2 group

In this work, we report a facile synthesis of four fluorinated zwitterionic heterogemini surfactants bearing branched CF3CF2CF2C(CF3)2- group with perfluoro-2-methyl-2-pentene as starting material. The surface activities of as-prepared four surfactants were found to be better than that of sodium perfluorooctanoate. Meanwhile, our fluorinated surfactants with double hydrophobic chains showed much better surface activities than the monomeric fluorinated surfactant. With the introduction of an alkyl chain, the CMC could be reduced more than 200 times to 6.30 × 10?5 mol/L, together with a surface tension of 18.66 mN/m. When a new fluorinated chain was introduced in the molecular structure, the CMC could be as low as 1.74 × 10?6 mol/L, along with a surface tension of 18.42 mN/m. When the alkyl chain length is 7, the surfactant has the same ability with the double fluorinated chain one to reduce the surface tension.

Process for preparation of oxyglutaric acid ester derivatives

A process for preparing an oxyglutaric acid ester derivative of the formula: STR1 in which each of R1 and R2 is C1-5 alkoxy, C1-7 aralkyloxy, C7-9 halogenated aralkyloxy or phenyl, R4 is a hydroxyl-protecting group, and R5 is C1-10 alkyl which may have a substituent, comprises the steps of reacting a methyl phosphonate derivative or methyl phosphine oxide derivative with an oxyglutaric acid mono-ester to give a reaction product which comprises an oxyglutaric acid derivative having a phosphorus-containing group and a pentenedioic acid mono-ester (by-product), removing the pendenedioic acid mono-ester from the reaction product to isolate the oxyglutaric acid derivative, and converting the isolated oxyglutaric acid derivative into the oxyglutaric acid ester derivative. A process for obtaining an optically active oxyglutaric acid ester derivative is also disclosed.
