The Raschig–Hooker process is a chemical process for the production of phenol, named after German chemist Friedrich Raschig. The main steps in this process are the production of chlorobenzene from benzene, hydrochloric acid and oxygen, and the subsequent hydrolysis of chlorobenzene to phenol. The Raschig–Hooker process is no longer used for commercial phenol production.
