4-hydroxybenzene-1 3-dicarbonitrile (CAS# 34133-58-9)
Intshayelelo
Yikhompawundi ephilayo. Ifomula yayo ye-molecular yi-C8H5NO2, ifomula yesakhiwo ngu-HO-C6H3 (CN)2.
sisiqina esingenambala esinevumba elimfiliba lephenol. Inomlinganiselo ophezulu wokunyibilika kunye neqondo lokubilisa, i-soluble kwi-solvents ye-organic efana ne-ethers, i-alcohol kunye ne-ketones, i-insoluble emanzini.
Olona setyenziso luphambili lwale khompawundi luphakathi olubalulekileyo kwi-organic synthesis. Ingasetyenziselwa ukuhlanganiswa kwee-polyesters zenoveli ukulungiselela i-optical, i-elektroniki kunye ne-pharmaceutical compounds. Ukongeza, inokusetyenziswa njengento ekrwada yokuncamathelisa okusebenzayo kunye neengubo.
Indlela yokulungiselela inkqubo inzima ngakumbi. Enye yeendlela eziphambili yindlela yokusabela kwe-p-phenolate sulfate kunye ne-sodium cyanide phantsi kweemeko ze-alkaline ukwenza i-4-hydroxy-2-phenylbenzonitrile, efunyenwe yi-acid-catalyzed decarboxylation.
Xa usebenzisa kunye nokuphatha, kufuneka ubeke ingqalelo kwimicimbi yokhuseleko. Inochuku oluthile, thintela ukudibanisa kwesikhumba kunye ne-inhalation. Izixhobo ezifanelekileyo zokukhusela, ezinjengeeglavu zelebhu kunye nezixhobo zokukhusela zokuphefumla, kufuneka zinxitywe ngexesha lokusebenza. Ukongezelela, ukudibanisa kunye ne-oxidizing agents kunye ne-acids eqinile kufuneka kugwenywe ukuphepha ukuphendula okuyingozi. Ngexesha lokugcinwa, gcina kude nomlilo kunye nemithombo yobushushu, kwaye ugcine isikhongozelo sivaliwe ukuthintela ukuguquguquka kunye nokuvuza.
