Preparation of Chlorphenesin
A method for green and efficient selective synthesis of chlorphenesin, the specific operations are as follows:
In a 500ml three-necked flask, 55.25g (0.60mol) of glycerol, 25.3g (0.28mol) of dimethyl carbonate, 25.8g (0.20mol) of p-chlorophenol, and 0.8g (0.02mol) of sodium hydroxide were sequentially added. Wherein, the molar ratio of glycerol: diethyl carbonate: p-chlorophenol in the system is 3: 1.4: 1, and the molar ratio of p-chlorophenol to sodium hydroxide is 1: 0.1. During feeding, keep stirring at a low speed of 30 rpm, heat to 110 °C, and react for 11 h. After the reaction was completed, the temperature was lowered to 22°C, the supernatant of 552.5g of saturated sodium chloride solution was added to the above-mentioned obtained reaction solution for washing, and then 552.5g of dichloromethane was added, and the mixture was evenly mixed and allowed to stand, layered, and the organic phase was taken, Concentrated to obtain a yellow-white solid, which was recrystallized with dichloromethane and filtered with suction to obtain a pure white powder product. The solid powder was vacuum-dried at 45 °C to obtain 33.23 g of chlorophenyl glycerol, with a calculated yield of 82%, detected by HPLC The purity is 95.4%.
The Detection Method of Chlorphenesin
Chlorphenesin is a white to off-white crystalline powder. It is a broad-spectrum bacteriostatic agent and preservative. It has a good bacteriostatic and bactericidal effect on Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, mold and other microorganisms. Currently, chlorphenesin is permitted in cosmetics as a preservative, but studies have shown that chlorphenesin may cause shortness of breath in infants. Therefore, infants are advised not to use chlorphenesin-containing products. Part 7: Finger Paints – Requirements and Measurement Methods” and the domestic GB 6675.14-2014 “Toy Safety Part 14: Finger Paint Requirements and Test Methods” allows chlorphenesin to be used as a restricted preservative, and specifies the maximum allowable use The concentration is 0.15%.
