Storage method

Storage Precautions[14] Store in a cool, dry and well-ventilated warehouse. Keep away from fire and heat sources. Packaging must beKeep it sealed and away from moisture. They should be stored separately from oxidants, alkalis, alcohols, etc. and avoid mixed storage. Equipped with the appropriate variety and quantity of fire equipment. The storage area should be equipped with emergency release equipment and suitable containment materials.

Synthesis method

Obtained from the reaction of succinic acid and phosphorus pentachloride. Add succinic acid, phosphorus pentachloride and anhydrous chloroform to the reaction pot in sequence. When the violent reaction slows down, heat to reflux. When all the reactants become liquid, evaporate the low boiling matter to recover chloroform, and then distill under reduced pressure to recover oxygen chlorine. phosphorus, further heat the residual liquid, continue distillation under reduced pressure, and collect the 95-110°C (2.67kPa) fraction, which is succinyl chloride. The yield is about 88%.

Purpose

1. Used in organic synthesis and as resin and plastic intermediates. [15]
