Preparation of Alkoxy Tetradecanoic Acid Ethanolamide
Put tetradecanoic acid into a reaction kettle and add ethanolamine (molar ratio 1:0.68). Heat it to 180 ℃ under stirring and react for 2 hours to generate amide esters. Continuously evaporate water during the reaction. After the reaction is completed, cool down and add an appropriate amount of NaOH, then add 0.68mol of ethanolamine. Heat up to 80 ℃ and react for 5 hours. Steam out the excess ethanolamine, replace the air in the kettle with N2, add a small amount of NaOH, and then add ethylene oxide in batches. React at 135 ℃ until the pressure does not decrease. Then cool down for backup.
Preparation of Sodium Alkoxytetradecanoic Acid Ethanolamide Sulfosuccinate Monoester Salt
Add the alkoxy tetradecanoic acid ethanolamide prepared above to the reactor, and then add maleic anhydride (molar ratio of 1:1.04), stirring at 140 ℃ for 4-5 hours. Then add an equal amount of sodium sulfite (prepared into a 40% aqueous solution) and react at 100 ℃ for 2 hours to obtain the product.
preparation of alkoxy decanoic acid ethanolamide put decanoic acid into a reaction kettle and add ethanolamine (molar ratio of the two to 1: 0.68), heat to 180 ℃ under stirring, react for 2 hours, and generate amide ester. Continuously distilled water during the reaction. After the reaction, add NaOH and 0.68mol of ethanolamine. The temperature is raised to 80 ℃ for 5h. The excess ethanolamine is steamed out, the air in the kettle is replaced with N2, a small amount of NaOH is added, and epoxide is added in batches, and the reaction is carried out at 135 ℃ until the pressure does not drop. Then cool down for standby.
Preparation of alkoxy decanoic acid ethanol amide sulfosuccinyl monoester sodium salt The prepared alkoxy decanoic acid ethanol amide is added to the reaction kettle, and then maleic anhydride is added (the molar ratio of the two is 1: 1.04), and stirred at 140 ℃ for 4-5h. Then, equimolar sodium sulfite (prepared into 40% aqueous solution) is added and reacted at 100 ℃ for 2h to obtain the product.
