Halogenoalkyl-polyglycol ethers and process for preparing them
Abstract
Abstract COMPOUNDS OF THE GENERAL FORMULA R1-CH(-X)-CH2-CH2-O-(CNH2NO-)M-R2 WHEREIN R1 STANDS FOR ALKYL CONTAINING 4 TO 20 CARBON ATOMS, X STANDS FOR CHLORINE OR BROMINE, R2 STAND FOR ALKYL CONTAINING 1 TO 20 CARBON ATOMS, A RADICAL OF AN ALKANE-CARBOXYLIC ACID CONTAINING 1 TO 18 CARBON ATOMS, THE PHENYL RADICAL, THE NAPHTHYL RADICAL OR AN ALKYL-PHENYL RADICAL CONTAINING 1 TO 12 ALIPHATIC CARBON ATOMS, THE BENZOYL OR BENZYL RADICAL OR THE RADICAL R1-CH(-X)-CH2-CH2- N STANDS FOR AN INTEGER FROM 2 TO 4 AND M STANDS FOR AN INTEGER FROM 2 TO 200, WHICH ARE USEFUL AS TENSIDES AND EMULSIFIERS, AND A PROCESS FOR PREPARING THEM BY REACTING A HALOGENO-METHYL ETHER OF THE FORMULA R3O(CNH2NO)M-CH2X IN WHICH X, N AND M HAVE THE MEANINGS GIVEN ABOVE, AND R3 STANDS FOR THE RADICAL -CH2CL OR -CH2BR OR HAS THE SAME MEANING AS R2, IN THE PRESENCE OF A FRIEDEL-CRAFTS CATALYST, AT 10 TO 100*C., WITH AN A-OLEFIN CONTAINING 8 TO 20 CARBON ATOMS.
