PhenolIcho chakakosha organic makemikari zvinyorwa, izvo zvinoshandiswa zvakanyanya mukugadzirwa kwezvakagadzirwa zvemakemikari akasiyana-siyana, antioxidants, kurapa maAgent, uye, zvakakosha kuti tinyatsogadzira tekinoroji ye phenol. Munyaya ino, isu tichaisa tekinoroji yekugadzira yechiitiko zvakadzama.

Kugadzirira kwe phenol kunowanzoitwa nekuita bandzene paine procalylene pamberi pekuvapo. Maitiro ekuita anogona kukamurwa kuita matanho matatu: danho rekutanga nderekuita kweBenzene uye Proparyylene kuumba cumene; Nhanho yechipiri ndeye oxidation ye cumene kuumba cumene hydropereroxide; uye danho rechitatu ndiko kuchinjika kweiyo cumene hydropereroxide kuumba phenol uye acetone.

Mudanho rekutanga, benzene uye procarycy inoitwa mukuvapo kweAcid Catalyst kuumba cumene. Kuita uku kunoitwa pakudziya kweanenge 80 kusvika ku100 degrees celsius uye kumanikidzwa kwegumi kusvika ku10 kg / cm2. Iyo Catalyst inoshandiswa ndeye kazhinji aluminium chloride kana sulfutic acid. Iyo yekugadzira chigadzirwa ndeye cumene, iyo yakaparadzaniswa kubva mukuita musanganiswa nekushanda.

Mudanho repiri, cumene iri oxidized nemhepo pamberi peiyo acid catalyst yekuumba crumene hydropereroxide. Kuita uku kunoitwa pakudziya kweanenge 70 kusvika 90 degrees celsius uye kumanikidzwa kweanenge 1 kusvika 2 kg / cm2. Iyo Catalyst yakashandiswa kazhinji inowanzo sulfutic acid kana phosphhoric acid. Iyo yekugadzira yechigadzirwa ndeye cumene hydropemeroxide, iyo yakaparadzaniswa kubva pakuita musanganiswa nekushanda.

Muchitanho chechitatu, Cumene Hydropemeroxide inocherwa muHupo hweAcid Catalyst kuumba phenol uye acetone. Kuita uku kunoitwa pakudziya kweanenge zana kusvika ku130 degrees celsius uye kumanikidzwa kwe1 kusvika ku2 kg / cm2. Iyo Catalyst yakashandiswa kazhinji inowanzo sulfutic acid kana phosphhoric acid. Iyo yekuita chigadzirwa isanganiswa ye phenol uye acetone, iyo yakaparadzaniswa kubva pakuita musanganiswa nekushanda.

Pakupedzisira, kuparadzaniswa uye kucheneswa kwe phenol uye acetone inoitwa nekureba. Kuti uwane zvigadzirwa zvakakwirira-zvakanyanyisa, nhevedzano yemakoronga inowanzoitika inowanzo shandiswa kuparadzaniswa uye kucheneswa. Iyo yekupedzisira chigadzirwa ndeye phenol, iyo inogona kushandiswa pakugadzirwa kwezvigadzirwa zvakasiyana zvemakemikari.

Mukupfupikisa, kugadzirira kwe phenol kubva kuBenzene uye propeygy kuburikidza nematanho matatu ari pamusoro apa anogona kuwana yakanyanya-yekuchena phenol. Nekudaro, maitiro aya anofanirwa kushandisa nhamba huru yeAcid CatalyStts, iyo inozokonzeresa zvakakomba zvekushandisa zvishandiso uye kusvibiswa kwezvakatipoteredza. Naizvozvo, dzimwe nzira itsva dzekugadzirira dzinogadzirwa kutsiva maitiro aya. Semuenzaniso, nzira yekugadzirira ye phenol uchishandisa biocatalystave zvishoma nezvishoma yashandiswa muindasitiri.
