Introduction

N,N-bis(hydroxyethyl) cocamide can be used as surfactant. It is a light yellow to amber viscous liquid, easily soluble in water, with good foaming, foam stabilization, penetration and decontamination, and resistance to hard water.

N,N-bis(hydroxyethyl) cocamide is a non-ionic surfactant. When the anionic surfactant is acidic, the thickening effect is particularly obvious. It can be compatible with a variety of surfactants. Can enhance the cleaning effect, can be used as an additive, foam stabilizer, foam aid, mainly used in the manufacture of shampoos and liquid detergents. It forms an opaque mist-like solution in water, which can be completely transparent under a certain stirring, and can be completely dissolved in different kinds of surfactants under a certain concentration, and can also be completely dissolved in low carbon and high carbon.

●  Direct synthesis of fatty acid and diethanolamine: This method is simple in process, but has high cost and many side reactions, and is generally rarely used.

●  Direct reaction between refined oil and diethanolamine, also known as one-step method. In practice, alkanolamides are usually made of fatty acid (FA) and excess diethanolamine (DEA) (1:2, 1:1.5, 1:1 type) to ensure complete fatty acid reaction. The resulting product is an equimolar amide with The association of DEA has good water solubility. The cost of this method is low, but the color of the product is deep, and the content of alkanolamide is only about 7O, so it lacks competitiveness in the international market. At present, domestic small and medium-sized manufacturers mostly use this method.

●  The ester exchange reaction between coconut oil and alcohol produces lauric acid ester, which is then reacted with diethanolamine to produce the product. Also called the two-step method. At present, large enterprises at home and abroad use the more advanced methyl ester method, which has a low reaction temperature, and the obtained products have light color, good transparency and high thickening performance. Among them, the content of lauric acid diethanolamide can reach more than 85%, and the cost of raw materials is the same as that of the one-step method, so the competitiveness of the product is strong.
