production method | 1 mol of solid dodecylamine is put into a reaction kettle for heating and melting, and a vacuum is drawn. The temperature was gradually increased to 100 ° C. And the temperature was maintained for 10-30 min of distillation under reduced pressure to remove the dodecylamine carbonate. After the melted dodecylamine was cooled to 30 ° C. With stirring, 1.1 mol of methyl acrylate was added dropwise under vigorous stirring. The reaction temperature was maintained at 25-30 °c during the addition. After completion of the dropwise addition, stirring was continued at 20-25 °c until the exotherm was completed. Excess methyl acrylate was then distilled off under reduced pressure. In addition, 1.1 mol of sodium hydroxide was added to the neutralization kettle and dissolved in water, and then the above reactant was added dropwise to an aqueous sodium hydroxide solution for saponification, and then the saponified was neutralized with an appropriate amount of hydrochloric acid to adjust the pH value to 8.2 to obtain the product. |
