Properties and stability

Stable properties under normal temperature and pressure.

Storage method

Store in a cool and dry place.

Synthesis method

1. Obtained from the reaction of acetone and chloroform: Add chloroform and acetone into the reaction pot at an ingredient ratio of 1:0.5, cool to 8°C, slowly add potassium hydroxide while stirring, and control the temperature not to exceed 15°C. After the addition is completed, maintain stirring at the same temperature for 2 hours, discharge, filter, and concentrate the filtrate until no distillate drips out. Stop heating, cool down to 25°C, add ice water, stir, precipitate crystals, centrifuge crystallization, centrifuge separation, wash the filter cake with distilled water until there is no chloride ion. Dry at 60-65°C for about 2 hours, sieve and package. The yield is 56% (based on chloroform). Raw material consumption quota: chloroform 1247kg/t, acetone 1688kg/t, potassium hydroxide 285kg/t.

Purpose

1. Mainly used as pharmaceutical raw materials to make antiseptics, antiemetics, and local analgesics. Its 1% aqueous solution or 5%-10% ointment can be used for disinfection and sterilization. It can also be used in organic synthesis.

2.Used as antiseptics, anesthetics, and cosmetic preservatives. The maximum allowable content (mass fraction) of cosmetics is 0.5%.
