PHENOL

Description

Phenol, which is also referred to as carbolic acid, Phenylic acid, benzophenol, hydroxybenzo and mono- hydroxy benzene, is used to produce a wide variety of chemical intermediates, including phenolic resins, bisphenol A, caprolactam, alkyl phenols, adipic acid, plasticizers, and others. Phenol can be shipped in water solutions to eliminate molten storage. Health and safety information is available through the appropriate Material Safety Data Sheet(MSDS).
