Phenolproduktion
WebThe chemistry of phenol production is a two-step synthesis. First, cumene is reacted with oxygen in air to form an intermediate compound, cumene hydroperoxide (CHP). Second, the CHP is decomposed with sulfuric acid to form the phenol and acetone co-products. Monitoring the process for CHP concentration is very important since WebPhenol finds applications as an industrial cleaner for machinery parts and electronic devices, as a raw material in the manufacturing of drugs and antioxidants, for making intense colored dyes, as a starting material for plastics and explosives such as picric acid, as a basic material in wood preservatives such as creosote, and in everyday …

WebThe cumene process ( cumene-phenol process, Hock process) is an industrial process for synthesizing phenol and acetone from benzene and propylene. The term stems from cumene (isopropyl benzene), the intermediate material during the process. It was invented by R. Ūdris and P. Sergeyev in 1942 (USSR), [1] and independently by Heinrich Hock in 1944.
