I-3-Bromo-5-chloropyridine-2-carboxylic acid (CAS# 1189513-50-5)

I-3-Bromo-5-chloropicolinic acid iyinhlanganisela ephilayo.

Ikhwalithi:
I-3-Bromo-5-chloro-2-pyridine carboxylic acid iyikristalu engenambala enezici ezihlukile zesakhiwo kanye ne-physicochemical. Iqinile ezingeni lokushisa legumbi futhi iyancibilika kwezinye izinyibilikisi zemvelo, njenge-methanol, i-dimethylformamide, njll. Inhlanganisela izinzile emoyeni futhi ingabhekana nokushintshashintsha kwamakhemikhali ngaphansi kwezimo ezithile.

Izicelo: Isakhiwo sayo samakhemikhali esikhethekile siyenza ibe nohlu olubanzi lwamandla okufaka isicelo.

Indlela:
Indlela evamile yokulungiswa kwe-3-bromo-5-chloro-2-pyridine carboxylic acid itholakala ngokuhlangana kwamakhemikhali. Ngokuqondile, ingaqala kusukela ku-2-pyrolinic acid noma i-2-pyridone, futhi ngemva kochungechunge lokusabela, ama-athomu e-bromine ne-chlorine angakwazi ukwethulwa ukuze ekugcineni akhe inhlanganisela ehlosiwe.

Ulwazi Lokuphepha:
Uma usebenzisa i-3-bromo-5-chloro-2-pyridine carboxylic acid, izinqubo ezifanele zokusebenza zokuphepha zidinga ukulandelwa. Leli ikhemikhali kanye nothuli noma isixazululo okufanele kugwenywe ngokuhogela. Izimpahla zokuzivikela ezifanele ezifana nezingubo zamehlo ezivikelayo, amagilavu ​​nezingubo zokuzivikela kufanele zigqokwe ngesikhathi sokuphatha. Inhlanganisela igcinwa futhi ilahlwe ngokuhambisana nemithethonqubo efanele futhi imfucuza ilahlwa ngendlela efanele.
