Benzoyl chloride, also known as benzoic chloride or benzenecarboxylic acid chloride, is commonly used in the production of dyes and resins, as well as in the synthesis of pharmaceutical drugs and perfumes. When exposed to rubber, benzoyl chloride can cause swelling, softening, discoloration, and eventually hardening and cracking of the rubber. This type of failure is most common in neoprene and nitrile rubber, and can be prevented by proper selection of the rubber material and its components.
