Properties and stability
1. Avoid contact with water, alcohols, strong oxidants, and strong alkalis.
2.This product is toxic. It is irritating and corrosive to skin, mucous membranes, eyes, etc. The workshop should be well ventilated and the equipment should be sealed. Operators must wear labor protection supplies. If it splashes on skin, rinse with plenty of water.
�How to save
1. Store in a cool, ventilated warehouse. Keep away from fire and heat sources. They should be stored separately from oxidants, alkalis, alcohols, etc. and avoid mixed storage. Equipped with corresponding varieties and quantities of fire-fighting equipment. The storage area should be equipped with emergency release equipment and suitable containment materials.
2. Packed in porcelain bottles, net weight 20kg. Store in a dry and ventilated place. Handle with care and transport according to regulations on toxic chemicals.
Synthesis method
Mix stearic acid and dimethylformamide, add a catalyst, and react with phosgene. Then nitrogen gas is used to remove the hydrogen chloride and excess phosgene generated by the reaction, and the product is distilled under reduced pressure to obtain the finished product. Raw material consumption quota: stearic acid 970kg/t, phosgene (98%) 420kg/t, dimethylformamide (98%) 10kg/t, liquid alkali (30%) 400kg/t.
Purpose
It is mainly used as an intermediate for color film couplers, and is also used as a raw material for the esterification of alcohols and other organic compounds.
