1,174,707. Phenol derivatives. GAF CORP. 16 May, 1968 [26 May, 1967], No. 23416/68. Heading C2C. [Also in Divisions C3 and G2] Sulphate esters of glycidol polyethers of the formula where R is H or alkyl or 1-18 C, R 1 is alkyl of 8-18 C and x is an integer from 3-30 are made by reacting the polyether of the above formula with sulphamic acid. The polyether is made by heating the appropriate alkyl phenol with glycidol in the presence of alkali. A list of phenols is given and in examples polyethers and sulphate esters are made wherein the value x is 4À5, 5, 6 and 17À4. |
