Our company has two phenol units. One of the units in Chemical Works No2 utilizing cumene process introduced from Mitsui Company of Japan,which produces 50000 ton phenol annually. The other unit in Chemical Works No3 was revamped on the basis of UOP licence by the Design Institute of BYPC,which produces 22500 ton per year. The technology for producing phenol of this two units are quite similar,both are taking benzene and propylene as fedstock,first get cumene through alkylationreaction,then cumene hydro peroxide is hydro peroxide decomposes into phenol and acetone,and the finish product is achieved after rectification,the main processes cover hydrocarbon reaction,oxideation,decomposition and reactification units. Phenol is an important chemical raw material,could the used in producing dyeintermediate,resin,bisphenolA,polycarbonate,fiber, medicine,agriculture pesticide and so on.
Pure phenol is colorless,diamond crystal with spcial odour.
Under the condition of long time storage,especially exposure to direct sunshine, it is easy oxygenized and turns into rose or dark brown.which is easy deliquescent. Phenol is a weak acid material and corosive. Burning will be caused if phenol touches skin. It is poisonous to people. Density is 1.071,boiling point is 181.8 C,melting point is 40.90 C ,Phenol is easily dissolved in alcohol,chloroform, diethylether,glycerin,carbon bisulfide,alkali liquor and acetic acid .Oxygn in the air can oxygenize phenol to produce quinone.
