Intshayelelo
I-2,4-Dibromobenzoic acid yi-organic compound. I-crystalline emhlophe okanye i-crystalline powder. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi olukhuselekileyo lwe-2,4-dibromobenzoic acid:
Umgangatho:
- Imbonakalo: Iikristale ezimhlophe okanye umgubo wekristale.
- Ukunyibilika: Inyibilika kwizinyibilikisi eziphilayo ezifana ne-ethanol, i-ether kunye nekloroform, enganyibilikiyo emanzini.
Sebenzisa:
- Inokusetyenziswa kwakhona njenge-antioxidant kunye ne-rubber additive, phakathi kwezinye izinto.
Indlela:
- Indlela yokulungiselela i-2,4-dibromobenzoic acid ifumaneka ikakhulu ngokuphendula kwe-bromination ye-benzoic acid. Kwinqanaba elithile, i-benzoic acid iqala ukusabela kunye ne-bromine xa kukho i-acid catalyst ukwenza i-bromobenzoic acid. Emva koko, i-asidi ye-bromobenzoic i-hydrolyzed ukunika i-2,4-dibromobenzoic acid.
Ulwazi ngoKhuseleko:
- I-2,4-Dibromobenzoic acid izinzile kwiqondo lokushisa, kodwa inokubola kumaqondo aphezulu okanye amadangatye avulekileyo ukuvelisa iigesi ezinobuthi.
- Iyacaphukisa kwaye inokubangela ukucaphuka kunye nokuphazamiseka ekudibaneni nolusu, amehlo, kunye nomgudu wokuphefumula.
- Amanyathelo afanelekileyo okhuseleko lomntu afana neeglavu zokukhusela, ukukhuselwa kwamehlo, kunye nezixhobo zokukhusela zokuphefumla kufuneka zithathwe xa usebenzisa, ukugcinwa kunye nokuphatha.
- Kufuneka igcinwe kude nemithombo yomlilo kunye ne-oxidizing agents kwaye igcinwe kwindawo epholileyo, kwindawo epholileyo.
