Ubungozi Nokuphepha

Amakhodi Engozi R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba.
R41 – Ingozi yokulimala okubi emehlweni
R37/38 – Ukucasula uhlelo lokuphefumula kanye nesikhumba.
R25 – Kunobuthi uma ugwinywe
Incazelo Yokuphepha I-S37/39 – Gqoka amagilavu ​​afanelekile kanye nokuvikela iso/ubuso
S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha.
S45 – Uma kwenzeka ingozi noma uzizwa ungaphilile, funa iseluleko sezokwelapha ngokushesha (bonisa ilebula noma nini lapho kunokwenzeka.)
S39 – Gqoka ukuvikela iso / ubuso.

3-bromo-2-chloro-6-picoline (CAS# 185017-72-5) Isingeniso

Kuyinhlanganisela yemvelo enefomula yamakhemikhali i-C7H7BrClN. Okulandelayo yincazelo yobunjalo bayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:Imvelo:
iqinile enombala omhlophe kuya kophuzi. Iphuzu layo lokuncibilika lilinganiselwa ku-63-65 degrees Celsius kanti ukuminyana kwalo lilinganiselwa ku-1.6g/cm³. Le nhlanganisela iyancibilika kuzincibilikisi zemvelo ezifana notshwala nama-ether ezingeni lokushisa elijwayelekile.

Sebenzisa:
Ivamise ukusetshenziswa njenge-reagent futhi imaphakathi ku-organic synthesis. Ingasetshenziswa njenge-catalyst, i-oxidant kanye ne-reductant yokuhlanganiswa kwezinhlobo ezahlukene zezinhlanganisela eziphilayo. Ngaphezu kwalokho, ingasetshenziselwa ukulungiswa kwezithako ezisebenzayo kanye nama-antimicrobial agents emkhakheni wezokwelapha.

Indlela:
Ingahlanganiswa ngezindlela ezihlukahlukene. Enye yezindlela ezivamile ukusabela nge-pyridine ne-bromoacetate, bese usabela nge-chloride yethusi ukuze uthole umkhiqizo ohlosiwe.

Ulwazi Lokuphepha:
Lapho usebenzisa futhi uphatha: Naka lezi zindaba zokuphepha ezilandelayo:
-Le nhlanganisela inamandla okubangela ukucasuka nokulimala emgudwini wokuphefumula, amehlo nesikhumba, futhi ukuxhumana okuqondile kufanele kugwenywe.
-ekusetshenzisweni kwenqubo kufanele kugweme ukuhogela uthuli noma umusi, isidingo sokugcina izimo ezinhle zokungenisa umoya.
-Izimpahla zokuzivikela ezifana namagilavu ​​okuzivikela, izibuko nezingubo zokuzivikela kufanele zigqokwe ngesikhathi sokusetshenziswa.
-Ungagcini noma uhlanganise le ngxube nama-oxidants aqinile, ama-asidi aqinile noma izisekelo eziqinile ukuze ugweme ukusabela okuyingozi.
-Lapho ulahla imfucuza, kuyadingeka ukuphatha kahle nokulahlwa ngokuhambisana nemithetho yendawo.
