4-BROMO-3 5-DICHLOROPYRIDINE(CAS# 343781-45-3)

Intshayelelo

I-4-Bromo-3,5-dichloropyridine i-organic compound kunye ne-chemical formula C5H2BrCl2N. Oku kulandelayo yinkcazo yobume bayo, ukusetyenziswa, ukulungiswa kunye nolwazi lokhuseleko:

Indalo:

I-4-Bromo-3,5-dichloropyridine yikristale engenambala okanye ephaphathekileyo emthubi enevumba elimnandi elimnandi. Indawo yayo yokunyibilika iphakathi kwe80-82°C kwaye indawo yayo yokubila iphakathi kwama-289-290°C. Ayinyibiliki emanzini kubushushu obuqhelekileyo, kodwa inyibilika kwizinyibilikisi eziphilayo ezifana ne-ethanol kunye nekloroform.

Sebenzisa:

I-4-Bromo-3,5-dichloropyridine isetyenziswa kakhulu kwishishini lemichiza. Yinto ebalulekileyo ephakathi kwe-pyridine compounds kwaye ingasetyenziselwa ukuhlanganiswa kwamanye ama-organic compounds kunye neziyobisi. Inozinzo oluhle lweekhemikhali kunye nokusebenza kwakhona, kwaye inokusetyenziswa njenge-catalyst, i-ligand, idayi kunye nezinto eziluhlaza ze-pesticide.

Indlela yokulungiselela:

Indlela yokulungiselela i-4-Bromo-3,5-dichloropyridine ngokuqhelekileyo iphunyezwa ngokuphendulwa kokutshintshwa kwepyridine. Indlela yokulungiselela esetyenziswa ngokuqhelekileyo ibandakanya ukusabela kwe-pyridine nge-bromine kunye ne-ferric chloride, kwaye ukuphendulwa kokutshintshwa kwenziwa phantsi kweemeko ezifanelekileyo zokufumana imveliso ekujoliswe kuyo. Inkqubo yokulungiselela idinga ukulawula ubushushu bokusabela, ixabiso le-pH kunye nexesha lokuphendula kunye nezinye iiparamitha zokufumana iimveliso ezicocekileyo.

Ulwazi ngoKhuseleko:

I-4-Bromo-3,5-dichloropyridine yinto ezinzileyo kwaye ikhuselekile phantsi kweemeko eziqhelekileyo, kodwa kusafuneka ukuba ubeke ingqalelo ekusebenzeni okukhuselekileyo. Inokungena emzimbeni ngokuphefumla, ukudibana nolusu kunye nokungeniswa. Ukuphefumla iqondo eliphezulu leegesi kunye nothuli kunokubangela ukucaphuka, kubangele ukuphefumla kunye nokungakhululeki kwamehlo. Ukuqhagamshelana nolusu kunokubangela ubomvu, ukuxubha kunye nokuphendula komzimba. Ukungeniswa kwekhompawundi kunokubangela ukuphazamiseka kwesisu kunye nemiphumo eyityhefu. Ke ngoko, izixhobo ezifanelekileyo zokukhusela kufuneka zinxitywe ngexesha lokusetyenziswa ukuthintela ukunxibelelana ngokuthe ngqo kunye nokuphefumla. Kwimeko yeengozi, unyango olungxamisekileyo kufuneka lwenziwe ngexesha kunye neengcali kufuneka zidityaniswe. Ukongezelela, kufuneka igcinwe kwindawo eyomileyo, epholileyo, kude nomlilo kunye ne-oxidizing agents.
