Phenol can be used to make dyes synthetic resin, can be made of plastic, can be synthetic, but also the manufacture of pesticides, salicylic acid, and so on. Phenol is the most simple phenols imported phenol, a weak acid. Phenol at room temperature under my company as a colorless crystal. Phenol toxic, there are corrosive, therefore operate to certain protective measures.

Phenol 若果 pink exposed to the air, but does not affect customers. Phenol was first recovered from coal tar, currently mostly synthetic methods. By the mid-1960s, began to use cumene production of phenol and acetone technical route, has developed half of the world production of phenol, currently used in the process of production of phenol, phenol accounted for more than 90% of the world production. Other production processes include toluene chloride, chlorobenzene France, sulfonated France. There are two methods of cumene and sulfonated production methods. Due to consume large amounts of sulfuric acid and sulfonated law caustic soda, our country will retain only a small number of sulfonated law means, and gradually to cumene production based.
