4-hydroxybenzene-1 3-dicarbonitrile (CAS# 34133-58-9)
Isingeniso
Kuyinhlanganisela yezinto eziphilayo. Ifomula yayo yamangqamuzana ithi C8H5NO2, ifomula yesakhiwo ithi HO-C6H3(CN)2.
iqinile elingenambala elinephunga elibi le-phenol. Inephuzu eliphezulu lokuncibilika nendawo yokubilisa, inyibilika kuzincibilikisi zemvelo njenge-ethers, utshwala nama-ketones, ezingancibiliki emanzini.
Ukusetshenziswa okuyinhloko kwalesi sakhiwo kuyingxenye ebalulekile ekuhlanganiseni kwe-organic. Ingasetshenziswa ekuhlanganiseni ama-polyester anoveli ekulungiseleleni ama-optical, electronic and pharmaceutical compounds. Ngaphezu kwalokho, ingasetshenziswa njengezinto ezingavuthiwe zokunamathisela okusebenzayo kanye nezingubo.
Indlela yokulungiselela inqubo iyinkimbinkimbi kakhulu. Enye yezindlela eziyinhloko ukusabela kwe-p-phenolate sulfate ne-sodium cyanide ngaphansi kwezimo ze-alkaline ukwakha i-4-hydroxy-2-phenylbenzonitrile, esuke itholwa yi-acid-catalyzed decarboxylation.
Lapho usebenzisa futhi uphatha, udinga ukunaka izindaba zokuphepha. Inokucasuka okuthile, gwema ukuthintana kwesikhumba nokuhogela. Izinto ezisetshenziswayo zokuvikela ezifanele, njengamagilavu zelabhu kanye nezinto zokuvikela ukuphefumula, kufanele zigqokwe ngesikhathi sokusebenza. Ngaphezu kwalokho, ukuxhumana nama-oxidizing agents kanye nama-acids aqinile kufanele kugwenywe ukugwema ukusabela okuyingozi. Ngesikhathi sokugcina, gcina kude nemithombo yomlilo neyokushisa, futhi ugcine isiqukathi sivaliwe ukuze uvimbele ukuvuvuka nokuvuza.
