INHIBITION OF COLOR FORMATION DURING SULFATION OF ETHOXYLATED ALCOHOLS AND ALKYL PHENOLS

摘要

Light-colored sulfates of ethoxylated long chain aliphatic alcohols and of ethoxylated alkylphenols are produced by carrying out the sulfation, using sulfur trioxide dissolved in liquid sulfur dioxide as the sulfating agent, in the presence of small amount of a borohydride such as sodium borohydride.
