[0079] Preparation of oleic acid diethanolamide borate (steady state)
[0080] Oleic acid diethanolamide borate (steady state) is oleic acid diethanolamide borate modified by alkylphenol polyethylene oxide ether salts at a temperature of 120°C. Its structural formula is as follows:
[0081]
[0082] The direct synthesis reaction equation is as follows:
[0083]
[0084]
[0085]
[0086] Add oleic acid into the reaction kettle, heat it to 100°C under the protection of nitrogen, add part of it at the ratio of oleic acid:diethanolamine=1:0.5mol, continue to heat up to 150-155°C, use NaOH standard solution to detect the content of free acid , when the content of free acid is lower than 1.5%, keep warm until the amine value of the reactant no longer changes to the end point. After being cooled to normal temperature, add boric acid in a molar ratio of oleic acid: boric acid = 1: 2, and use concentrated H 2 SO 4 As a catalyst, raise the temperature to 170°C, stir at c...
