- 1 - Abstract: Bisphenol derivatives, process for their manufacture, and their use as surfactants Compounds of the general formula X-Y-O-(-A-O-Y-O-)m-A-O-Y-X (1) wherein X denotes a radical of the general formula [R1-Gp-(O-CHR2-CHR3-)n]2N- (1a) in which R1 is a saturated aliphatic radical having 6 to 30 carbon atoms or an unsaturated aliphatic radical having one or several ethylenic bonds and 6 to 30 carbon atoms, G is phenylene or naphthylene, p is zero or 1, R2 and R3 are hydrogen or methyl, but are not both methyl, and n is a number from 0 to 25, Y denotes a radical of the formula Image (1b) in which R2 and R3 have the indicated meanings and q represents identical or different numbers from 0 to about 200, A denotes a radical of the general formula Image (1c) in which R4 and R5 are hydrogen or alkyl having 1 to carbon atoms, and m is a number from zero to 5, n and not both being zero, are obtained by subjecting 2 moles of an amine of the general formula H-X (2) - 1a - in which X has the indicated meaning, to a condensation reaction with a bis-epoxide of the general formula Image (3) in which A and m have the indicated meaning, at tempera- tures from 80 to 200°C in the presence of an acid catalyst and reacting the condensation product with ethylene oxide and/or propylene oxide at 100 to 200°C in the presence of a basic catalyst. The products are suitable for use as surfactants, in particular as dispersing agents.
