PhenolNdilo chinthu chofunikira kwambiri cha organic chopangira, chomwe chimagwiritsidwa ntchito kwambiri popanga mankhwala osiyanasiyana, monga ma pulasitiki, ma antioxidants, oyeserera, etc. Chifukwa chake, ndikofunikira kudziwa kupanga ukadaulo wa phenol. Munkhaniyi, tidziwitsa kupanga ukadaulo wa phenol mwatsatanetsatane.

Kukonzekera kwa phenol nthawi zambiri kumachitika ndi Pulogalamu kukhala Pulogalamu pamaso pa othandizira. Njira yomwe ingachite itha kugawidwa pamasitepe atatu: gawo loyamba ndi momwe Benzane ndi Propynenera kuti apange chimbale; Gawo lachiwiri ndi ma okosidwe a Cumene kuti apange chipilala hydroproride; Ndipo gawo lachitatu ndi chovala cha cumene hydroproeroxide kupanga phenol ndi acetone.

Mu gawo loyamba, Benzene ndi Propylene adachitidwa pamaso pa acid acid kuti apange chimbale. Izi zimachitika pa kutentha pafupifupi 80 mpaka 100 madigiri Celsius komanso kukakamizidwa pafupifupi 10 mpaka 30 kg / masentimita. Chothandizira chomwe chimagwiritsidwa ntchito nthawi zambiri chimakhala aluminiyam chloride kapena sulfuric acid. Chogulitsacho chimakhala chofufumitsa, chomwe chimalekanitsidwa ndi osakaniza ndi distillation.

Mu gawo lachiwiri, chipilala chimakhala ndi mpweya pamaso pa chothandizira cha acid kuti chikhale cha cumene hydroprorroxide. Izi zimachitika pa kutentha pafupifupi 70 mpaka 90 madigiri Celsius komanso kukakamizidwa pafupifupi 1 mpaka 2 kg / cm2. Chothandizira chomwe chimagwiritsidwa ntchito nthawi zambiri chimakhala ma sulfuric acid kapena phosphoric acid. Chogulitsacho chimakhala cha cumene hydropherroxide, chomwe chimalekanitsidwa ndi osakaniza ndi distillation.

Mu gawo lachitatu, CEMEne Hydropheroxide imatsukidwa pamaso pa acid acid kuti apange phenol ndi acetone. Izi zimachitika pamtunda wa madigiri 100 mpaka 130 Celsius komanso kukakamizidwa pafupifupi 1 mpaka 2 kg / cm2. Chothandizira chomwe chimagwiritsidwa ntchito nthawi zambiri chimakhala ma sulfuric acid kapena phosphoric acid. Chojambulacho ndi chisakanizo cha phenol ndi acetone, zomwe zimasiyanitsidwa ndi osakaniza ndi distillation.

Pomaliza, kulekanitsidwa ndi kutsuka kwa phenol ndi acetone kumachitika ndi distillation. Kuti mupeze zinthu zapamwamba kwambiri, mizati ingapo ya distillation nthawi zambiri imagwiritsidwa ntchito polekanitsa ndi kuyeretsa. Chogulitsa chomaliza ndi phenol, chomwe chingagwiritsidwe ntchito popanga mankhwala osiyanasiyana mankhwala.

Mwachidule. Komabe, njirayi imafunikira kugwiritsa ntchito othandizira ambiri acid, omwe angapangitse chilengedwe chachikulu cha zida ndi kuwonongeka kwa chilengedwe. Chifukwa chake, njira zina zokonzekera zatsopano zimapangidwira kuti zisinthe njirayi. Mwachitsanzo, njira yokonza phenol pogwiritsa ntchito Biocatalyst idagwiritsidwa ntchito pang'onopang'ono m'makampani.
