Ibikoresho bya phenol

Phenolni imiti itandukanye yimiti ifite uburyo butandukanye bwo gusaba mu nganda nubushakashatsi. Imyiteguro yubucuruzi ikubiyemo inzira yiminota myinshi itangirana na okidation ya cyclofexane. Muriki gikorwa, Cyclofexane ni okiside murukurikirane rwimiryango iringaniye, harimo nacclohexon na cyclofexanone, hanyuma ihinduka fenol. Reka dushuke muburyo burambuye. 

 

Gutegura ubucuruzi bwa Fhonol bitangirana na okidation ya cyclofexane. Iyi reaction ikorwa imbere yuburenganzira bwa okiside, nko mu kirere cyangwa ogisijeni nziza, na catalyst. Umusemburo ukoreshwa muriyi reaction ni uruvange rwibyuma byinzibacyuho, nka Cobalt, Manganese, na Bromine. Imyitwarire ikorwa ahantu hazamutse hamwe nigitutu, mubisanzwe kuva kuri 600 kugeza 900°C na 200 kugeza 200, mu kirere.

 

Okidation ya Gyclorex yatangajwe mugushiraho urukurikirane rw'uruhererekane, harimo na cyclofexanol na cyclofexanone. Izi ntera noneho zihinduka muburyo bwihuse mu ntambwe ikurikira. Iyi reaction ikorwa imbere ya aside igisekuru, nka acide sulfuric cyangwa aside hydrochloc. Umusemburo utera umwuma wa cyclofexanon na cyclofexone, bikaviramo gushinga fenol n'amazi.

 

Ibisubizo byavuyemo noneho byezwa na divalilation hamwe nubundi buryo bwo kweza kugirango ukureho umwanda nibindi bicuruzwa. Gahunda yo kwezwa iremeza ko ibicuruzwa byanyuma bihuye nibisabwa kwera kubisabwa bitandukanye.

 

Fhenol ikoreshwa muburyo butandukanye, harimo umusaruro wa Polycarbonates, Bisphenol a (BPA), ibyokurya bya penolic, nibindi bice bitandukanye. Polycarbonates ikoreshwa cyane mugukora ibikoresho bya pulasitike, lens, nibindi bikoresho bya optique bitewe no gukorera mu mucyo no kurwanya ingaruka. BPA ikoreshwa mu musaruro wa epoxy hamwe nibindi bihumanya, amatara, no komatanya. Ibisohokamo byanduye bikoreshwa mugukora ibihumanye, amatara, hamwe nibikorikori kubera kurwanya cyane ubushyuhe n'imiti.

 

Mu gusoza, gutegura ubucuruzi bwa fenol birimo okiside ya cyclofexane, hakurikiraho ihinduka ryimiryango hagati muri fenol no kweza ibicuruzwa byanyuma. Ibisubizo byavuyemo bikoreshwa muburyo butandukanye, harimo umusaruro wibikoresho bya pulasitike, kumenyera, amatara, no komatanya.
