Understanding Cumene: Properties, Production, and Safety for Industrial Users
Cumene, scientifically known as isopropylbenzene (CAS 98-82-8), is an organic compound with a distinct set of properties that define its industrial relevance. As a colorless liquid with a characteristic sharp, gasoline-like odor, it is highly flammable. Its boiling point is around 152 °C, and it has a density of approximately 0.862 g/cm³. While its solubility in water is negligible, it readily dissolves in common organic solvents like acetone and ethanol.
Commercially, Cumene is predominantly produced through the Friedel–Crafts alkylation of benzene with propylene. This process involves using catalysts, with zeolite-based catalysts being the modern standard for efficient production. The efficiency of this method generally ranges between 70-75%, with byproducts such as polyisopropyl benzenes also forming. Older methods utilized sulfuric acid or solid phosphoric acid catalysts, but these have largely been superseded due to environmental and efficiency concerns.
Safety is a critical consideration when handling Cumene. Its flammability (flash point around 43 °C) necessitates strict adherence to safety protocols to prevent ignition. Furthermore, Cumene can form peroxides through autoxidation under certain conditions, which poses a safety hazard. Therefore, regular testing for peroxides is advised before heating or distilling the material. In terms of health hazards, exposure can cause irritation to the skin, eyes, and respiratory tract. NIOSH recommends an occupational exposure limit (TWA) of 50 ppm (245 mg/m³) with skin contact noted.
For industrial users, understanding these properties and safety aspects is crucial for effective and safe handling. NINGBO INNO PHARMCHEM CO.,LTD. provides high-purity Cumene and relevant safety data (SDS) to support its clients. By prioritizing safety and quality in sourcing, manufacturers can ensure the reliable use of Cumene for its critical applications, including phenol and acetone production, fuel additives, and synthetic fragrances.
