摘　　要：提出一步法由棉籽油酸甲酯与二乙醇胺缩合高选择性地合成棉籽油酸二乙醇酰胺的工艺。适宜的一步法工艺条件是：０７％ＫＯＨ、７０℃、稍减压（残压约７３ｋＰａ）、反应２ｈ。实验室制备的１∶１６型棉籽油酸二乙醇酰胺接近椰子油酸二乙醇酰胺的去污力，它与ＴＸ１０及烷基苯磺酸钠共用可使０＃柴油形成微乳液，它能使普通碳钢耐５ｍｏｌ／Ｌ盐酸的锈蚀。An improved process, one step process is presented for the synthesis of cottonseed fatty acid diethanolamide from cottonseed fatty acid methyl ester condensed with diethanolamine.The reaction is carried out rapidly and selectively at 70℃ and slightly reduced pressure for 2h with 0.7% KOH as catalyst (based on the weight of reactant). The cottonseed fatty acid diethanolamide synthesized has a detersive power which approaches to that of coconut fatty acid diethanolamide. It can microemulsify 0 # diesel oil and offer ordinary steel resistance to acid corrosion.
