PhenolNibikoresho byingenzi byimiti mbisi yibikoresho, bikoreshwa cyane mugukora imiti itandukanye, nka plastioxizate, antioxidakene, nibindi rero, ni ngombwa cyane kumenya ikoranabuhanga ryibintu bya fenol. Muri iki kiganiro, tuzamenyekanisha ikoranabuhanga ryo gukora fenol muburyo burambuye.

 Ikoreshwa rya fenol

 

Gutegura Fhonol muri rusange bikorwa no gufata bengene hamwe na propylene imbere ya katali. Inzira yimyitwarire irashobora kugabanywamo intambwe eshatu: Intambwe yambere nuburyo bwa benzene na propylene kugirango bakore cumene; Intambwe ya kabiri ni okidation ya cumene kugirango ikore camene hydropexide; n'intambwe ya gatatu ni nziza ya cumene hydroperoxide kugirango ikore phenol na acetone.

 

Mu ntambwe yambere, benzene hamwe na propylene bitwawe imbere ya aside ihinduka kugirango ikore camene. Iyi myitwarire ikorwa ku bushyuhe bwa selisiyusi hafi 80 kugeza 100 nigitutu cya 10 kugeza 30 kg / cm2. Umusemburo wakoreshejwe ni aluminium chloride cyangwa aside sulfuric. Ibicuruzwa bya reaction ni cumene, bitandukanijwe kuva imvange ya reaction na ditelilation.

 

Mu ntambwe ya kabiri, Cumene ni okiside hamwe n'umwuka imbere ya aside ihinduka kugirango ikore camene hydropexide. Iyi reaction ikorwa mubushyuhe bwa selgedes zigera kuri 70 kugeza kuri 90 nigitutu cya 1 kugeza 2 kg / cm2. Umusemburo wakoreshejwe ni aside sulfuric cyangwa aside fosiforic. Ibicuruzwa bya reaction ni cumene hydroperoxide, bitandukanijwe kuva imvange ya reaction na ditelilation.

 

Mu ntambwe ya gatatu, Cumene Hydropexide irasukurwa imbere ya aside icide kugirango ikore phenol na acetone. Iyi myitwarire ikorwa ku bushyuhe bwa selisiyusi igera kuri 100 kugeza 130 nigitutu cya 1 kugeza 2 kg / cm2. Umusemburo wakoreshejwe ni aside sulfuric cyangwa aside fosiforic. Ibicuruzwa bya reaction ni uruvange rwa FHENOL na Acetone, bitandukanijwe kuva imvange ivanze na divalilation.

 

Hanyuma, gutandukana no kweza Fenol na Acetone bikorwa na Tarlilation. Kugirango ubone ibicuruzwa byisuku, urukurikirane rwibigo byitaweho mubisanzwe bikoreshwa mugutandukana no kwezwa. Ibicuruzwa byanyuma ni phenol, bishobora gukoreshwa mugukora ibicuruzwa bitandukanye.

 

Muri make, gutegura Fhonol kuva Bejene na propylene banyuze mu ntambwe eshatu zavuzwe haruguru zishobora kubona fenol nziza. Ariko, iyi nzira ikeneye gukoresha umubare munini wa acide, azatera ibikoresho bikomeye byogurika no kwanduza ibidukikije. Kubwibyo, uburyo bushya bwo kwitegura bwateguwe kugirango asimbuze iyi nzira. Kurugero, uburyo bwo gutegura bwa fenol ukoresheje biocatalys yakoreshejwe buhoro buhoro mu nganda.
