Properties and stability
1. Avoid contact with humid air, and contact with strong alkali, oxidants, water, and alcohol is strictly prohibited.
2.This product is toxic. It is highly corrosive and will easily decompose after absorbing water, producing hydrogen chloride gas. Operators should wear protective equipment and equipment should be sealed to prevent leakage. The workshop should be well ventilated.
Storage method
Seal and store in a dry place. Packed in glass bottles, they should be waterproof, sun-proof and sealed. Transport according to toxic chemical regulations.
Synthesis method
Reaction of adipic acid and thionyl chloride: Put adipic acid and thionyl chloride into the reaction pot, reflux chlorine at 90-95°C for 5 hours, let cool, and remove the remaining thionyl chloride under reduced pressure to obtain Finished product. Raw material consumption quota: adipic acid 830kg/t, thionyl chloride 1660kg/t.
Purpose
Organic Synthesis. Organic intermediates. It is used medicinally to synthesize cholecystic acid.
