Embodiment 1
[0025] Add 52g of sodium bisulfite, 0.08g of ethylenediaminetetraacetic acid and 80g of water into a closed reaction kettle, stir for 10 minutes to dissolve, then slowly press 38g of propylene oxide into the kettle with nitrogen gas, raise the temperature to 70°C, and seal it. Reaction 0.5hr, the maximum pressure in the process can reach 3atm, the pressure is almost zero when the reaction is complete, the residual amount of sodium bisulfite is 0.03%, and the active substance is 165g of sodium hydroxypropyl sulfonate aqueous solution with 50.4% of the output, which is directly used in The next step is esterification.
[0026] In the four-necked flask that stirrer, thermometer, long-necked dropping funnel, reflux condenser and water separator are equipped with, add coconut oil 100g, 50.4% sodium hydroxypropyl sulfonate 135g, catalyst zinc oxide 0.4g, Carry out mixing preheating, after treating that coconut oil all melts, control stirring speed to be 200rpm, gradually heat up and...
Embodiment 2
[0030] Add 52g of sodium bisulfite, 0.16g of maleic acid and 80g of water into a closed reaction kettle, stir for 10 minutes to dissolve, then slowly press 32g of propylene oxide into the kettle with nitrogen, raise the temperature to 60°C, and conduct a closed reaction for 1.5 hr, the maximum pressure in the process can reach 2.6atm, the pressure is almost zero when the reaction is complete, the residual amount of sodium bisulfite is 0.016%, and the active substance is 160g of 51.8% sodium hydroxypropyl sulfonate aqueous solution obtained from the discharge, which is directly used for the following One-step esterification reaction.
[0031] In a four-necked flask equipped with a stirrer, a thermometer, a long-necked dropping funnel, a reflux condenser and a water separator, add 100 g of lauric acid, 115 g of 51.8% sodium hydroxypropyl sulfonate, and 0.2 g of catalyst zinc oxide, and carry out Mix and preheat. After the lauric acid is completely melted, control the stirring sp...
Embodiment 3
[0035] Add 52g of sodium bisulfite, 0.14g of succinic acid and 80g of water into a closed reaction kettle, stir for 10 minutes to dissolve, then slowly press 32g of propylene oxide into the kettle with nitrogen gas, raise the temperature to 50°C, and react in a closed reaction for 2 hours. The maximum pressure in the process can reach 1 atm, and the pressure is almost zero when the reaction is complete. The residual amount of sodium bisulfite is 0.008%, and 160g of sodium hydroxypropyl sulfonate aqueous solution with an active substance of 48.6% is obtained from the discharge, which is directly used in the next step of esterification reaction.
