Title:
IMPROVEMENT FOR ETHOXYLATING WIDE RANGE OF PRIMARY ALCOHOLS
Document Type and Number:
Japanese Patent JPS5738736
Kind Code:
A
Abstract:
A process is provided for the preparation of stable, nonionic surface active agents which comprises in a first stage, reacting ethylene oxide with a primary monohydric alcohol having a range of chain lengths containing 10 to 20 carbon atoms in the presence of an acid catalyst for the time necessary to obtain an adduct containing 1 to 6 moles of ethylene oxide and then in a second stage, reacting ethylene oxide with the neutralized and washed reaction product from the first stage in the presence of an alkaline catalyst for the time necessary to prepare a stable, liquid nonionic surface active agent.
