Abstract
PURPOSE: To obtain the titled compound useful for imparting an aroma to a detergent product with improved (reduced) bad odor, by sulfating an ethoxylate with a hydroxy compound selected from methyl and ethyl ethers of glycols in a specific weight based on the ethoxylate.
CONSTITUTION: An ethoxylate of the formula RO-(C2H4O)n-H [R is 8W20C straight or branched chain alkyl; n is about 1W20] is sulfated with gaseous sulfur trioxide diluted with an inert gas, and the resultant sulfation product is then neutralized to give the titled compound. Prior to the sulfation, a hydroxy compound of formula (R' is H, CH3, C2H5, etc.; R" is H or CH3 ; m is 1 or 2) selected from methyl and ethyl ethers, of glycols, e.g. ethylene glycol or diethylene glycol, is added to the reaction system in an amount of 0.5W10pts.wt. based on 100pts.wt. ethoxylate. The amount of the hydroxy compound in an amount less than the lower limit weakens the effect on preventing the smelling.
