摘要：
A method of preparing hydroxyl substituted ammonio carboxylates comprising a single step of reacting an epoxy ester with a tertiary amine in aqueous alcohol, yielding directly said hydroxyl substituted ammonio carboxylates. The hydroxyl substituted ammonio carboxylates are useful as detersive surfactants and as oral anti-ulcer agents.
