Benzoyl chloride

Benzoyl chloride is an organic compound with the chemical formula C7H5ClO and CAS number 98-88-4. It belongs to the acyl chloride family and has a molecular weight of 140.56 g/mol. This substance is classified as corrosive and toxic, requiring careful handling in industrial applications. It serves as an important intermediate in organic synthesis and chemical manufacturing processes.

Benzoyl chloride is a colorless to slightly yellow liquid at room temperature with a characteristic pungent, irritating odor. It has a boiling point of approximately 197°C and is sensitive to moisture, readily hydrolyzing in water to form benzoic acid and hydrochloric acid. The compound is soluble in organic solvents like benzene, ether, and chloroform but reacts violently with water and alcohols.

Benzoyl chloride is primarily used as an intermediate in organic synthesis for producing pharmaceuticals, dyes, perfumes, and resins. It serves as a benzoylating agent in the manufacture of benzoyl peroxide, used in plastics and cosmetics. The compound is also employed in the production of benzophenone derivatives, pharmaceutical intermediates, and various specialty chemicals in industrial applications.

Benzoyl chloride requires strict safety measures due to its corrosive and toxic nature. Personnel must wear full protective equipment including chemical-resistant gloves, safety goggles, face shields, and protective clothing. Work should be conducted in well-ventilated areas or under fume hoods. Avoid contact with skin, eyes, and respiratory system. Keep away from moisture and incompatible materials during handling operations.

Benzoyl chloride must be stored in tightly sealed, dry containers away from moisture, heat, and ignition sources. Storage areas should be cool, well-ventilated, and equipped with appropriate containment systems. Keep separated from water, alcohols, bases, and oxidizing agents to prevent dangerous reactions. Use corrosion-resistant materials for storage containers and ensure proper labeling according to GHS requirements.

Immediate action is required for benzoyl chloride contact due to its corrosive properties. For skin contact, remove contaminated clothing and flush affected areas with plenty of water for at least 15 minutes. In case of eye contact, rinse immediately with water and seek medical attention. If inhaled, move to fresh air and get medical help. Never induce vomiting if ingested.

Benzoyl chloride disposal must comply with local and European waste regulations as hazardous chemical waste. The substance cannot be disposed of through regular waste streams due to its corrosive and toxic properties. Contact licensed hazardous waste disposal companies for proper treatment. Small quantities can be neutralized carefully with appropriate bases under controlled conditions by trained personnel only.

Benzoyl chloride is classified under ADR as Class 8 (corrosive substances), Packing Group II, indicating high transport risk. Transportation requires proper UN-approved packaging, appropriate labeling with GHS05 and GHS07 pictograms, and compliance with dangerous goods regulations. Vehicles must carry proper documentation, emergency procedures, and trained personnel familiar with handling corrosive materials during transport operations.

Benzoyl chloride is regulated under European REACH and CLP regulations due to its hazardous properties. It carries the signal word 'Danger' and is classified for acute toxicity, skin corrosion, and skin sensitization. The substance is not listed as SVHC (Substance of Very High Concern). Users must comply with safety data sheet requirements, worker protection measures, and proper classification and labeling standards.
