From Wikipedia, the free encyclopedia
Phenol, also known as carbolic acid and phenic acid, is an organic compound. It has the chemical formula C6H5OH. It is a white crystalline solid at room temperature. The molecule is made up of a phenyl (-C6H5). This phenyl is bonded to a hydroxyl (-OH) group. It is made on a large scale (about 7 billion kg every year).[3] It is only a little bit acidic but it must be handled carefully because it can burn human skin.
