Phenolinonyanya kukosha organic chemical raw material, iyo inoshandiswa zvakanyanya mukugadzirwa kwezvinhu zvakasiyana-siyana zvemakemikari, zvakadai seplasticizers, antioxidants, kuporesa vamiririri, nezvimwewo. Nokudaro, zvakakosha zvikuru kugona teknolojia yekugadzira phenol.Muchikamu chino, tichaunza tekinoroji yekugadzira phenol zvakadzama.

Kugadzirira kwe phenol kunowanzoitwa nekuita benzene nepropylene pamberi pezvinokonzeresa.Maitiro ekuita anogona kukamurwa kuita matanho matatu: danho rekutanga kuita kwebenzene uye propylene kuumba cumene;danho rechipiri ndiko oxidation ye cumene kuita cumene hydroperoxide;uye danho rechitatu kutsemuka kwecumene hydroperoxide kuita phenol uye acetone.

Padanho rekutanga, benzene nepropylene zvinoitwa pamberi peiyo acid catalyst kuumba cumene.Kuita uku kunoitwa patembiricha inenge 80 kusvika 100 madhigirii celsius uye kumanikidza kweanenge 10 kusvika 30 kg/cm2.Iyo catalyst inoshandiswa inowanzo aluminium chloride kana sulfuric acid.The reaction product is cumene, iyo inoparadzaniswa kubva kune reaction musanganiswa ne distillation.

Munhanho yechipiri, cumene inoiswa oxidized nemhepo pamberi pe acid catalyst kuumba cumene hydroperoxide.Kuita uku kunoitwa pakudziya kwe70 kusvika 90 degrees Celsius uye kumanikidza kwe1 kusvika 2 kg/cm2.Iyo catalyst inoshandiswa inowanzo sulfuric acid kana phosphoric acid.Iyo reaction product ndeye cumene hydroperoxide, iyo inoparadzaniswa kubva kune reaction musanganiswa ne distillation.

Padanho rechitatu, cumene hydroperoxide inotsemuka pamberi pe acid catalyst kuumba phenol uye acetone.Kuita uku kunoitwa pakudziya kwe100 kusvika 130 degrees Celsius uye kumanikidza kwe1 kusvika 2 kg/cm2.Iyo catalyst inoshandiswa inowanzo sulfuric acid kana phosphoric acid.Iyo reaction product musanganiswa we phenol uye acetone, iyo inoparadzaniswa kubva kune reaction musanganiswa ne distillation.

Pakupedzisira, kuparadzaniswa uye kucheneswa kwe phenol uye acetone kunoitwa ne distillation.Kuti uwane zvigadzirwa zvepamusoro-soro, mutsara wemakoramu e distillation anowanzoshandiswa kuparadzanisa uye kuchenesa.Chigadzirwa chekupedzisira chinonzi phenol, chinogona kushandiswa pakugadzirwa kwezvinhu zvakasiyana-siyana zvemakemikari.

Muchidimbu, kugadzirira kwephenol kubva benzene uye propylene kuburikidza nematanho matatu ari pamusoro apa anogona kuwana yakakwira-kuchena phenol.Nekudaro, kuita uku kunoda kushandisa nhamba yakakura yeasidhi catalysts, izvo zvinozokonzeresa kuparara kwemidziyo uye kusvibiswa kwezvakatipoteredza.Nokudaro, dzimwe nzira itsva dzekugadzirira dzinogadzirwa kuti dzitsive iyi nzira.Semuenzaniso, nzira yekugadzirira ye phenol inoshandisa biocatalysts yakashandiswa zvishoma nezvishoma mumhizha.
