Abstract

1296352 Polyoxyethylated quaternary derivatives UNILEVER Ltd 24 Sept 1969 [25 June 1968 12 July 1968] 17274/72 and 17275/72 Divided out of 1296351 Heading C3R [Also in Division C2] The invention comprises polyethyleneoxide quaternary ammonium compounds of the formula wherein X denotes an anion and (a) R 1 denotes C 15 -C 18 alkyl-O-(EO) x CH 2 CHOHCH 2 - C 17 H 35 alkyl-COO-(EO) x -CH 2 CHOHCH 2 - or C 17 H 35 alkyl-CONH-(EO) x -CH 2 CHOHCH 2 - (wherein x is from 3 to 40); (b) R 1 denotes (wherein x or y is at least 3 and (x+y) is 4 to 40); (c) R 1 denotes or (wherein x or y or z is at least 3 and (x+y+z) is 5 to 40); (d) R 1 denotes X-, R 2 R 3 R 4 N<SP>+</SP>-CH 2 CHOHCH 2 -O-(EO) z -CH 2 CHOHCH 2 - (wherein z is 4À5 to 34); (e) R 1 denotes X<SP>-</SP>, R 2 R 3 R 4 N<SP>+</SP>- CH 2 CHOHCH 2 -O-(EO) m -(CH.CH 3 -CH 2 O) y -(EO) n -CH 2 CHOHCH 2 - (wherein y is about 31, m or n is at least 3 and (m+n) is from 4 to 50); and (f) R 1 denotes (EO) x -O-CH 2 CH 2 -, R 2 denotes C 17 H 35 -COOCH 2 CH 2 - or (EO) y -O-CH 2 -CH 2 -, R 3 denotes C 17 H 35 -COOCH 2 CH 2 - or (EO) z -O-CH 2 CH 2 - (wherein x or y or z is at least 2, and (x+y+z) is 3 to 40); and wherein R 2 , R 3 and R 4 in (a), (b), (c), (d) and (e), and R 4 in (f) denote straight-chain, branched or cyclic alkyl, aryl, alkaryl, aralkyl or heterocyclic groups which may be further substituted except for anionic groups, or two or more of such symbols may together with the quaternary nitrogen atom form a heterocyclic ring or part of the repeating unit of a polyethyleneimine backbone. The anion X may represent chloride, bromide, iodide, sulphate, acetate or phosphate anions. The above compounds may be prepared by reacting a suitable polyethylene oxide compound with epichlorohydrin and subsequently with a tertiary amine. Alternatively, a suitable amine-ethylene oxide condensate may be quaternized at the nitrogen atom. Uses.-For detergent bars and as lime soap scum dispersants.
