Phosphorbetaines and process for making them

摘要

Production of novel phosphobetaines of general formula I <IMAGE> I in which R1 and R2 each stand for organic groups having from 1 to 18 carbon atoms, and R1 or R2 may be identical with the substituent R, the substituent R being a radical of the general formula II <IMAGE> II in which R3 and R4 each stand for organic groups having from 1 to 18 carbon atoms, and/or hydrogen atoms, and R5 stands for a linear or branched alkyl group having from 1 to 4 carbon atoms, which may optionally have a halogen or hydroxylic group substituent attached thereto.
