2-Mercapto Pyrazine (CAS#38521-06-1)
| I-WGK Germany | 3 |
Isingeniso
I-2-Mercaptopyrazine iyinhlanganisela ye-organic enefomula yamakhemikhali i-C4H4N2S. Iqinile njengekristalu emhlophe enephunga elimnandi. Okulandelayo yincazelo yemvelo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha lwe-2-Mercaptopyrazine:
Imvelo:
-Ukubukeka: I-crystalline emhlophe eqinile
Isisindo samangqamuzana: 112.16g/mol
-indawo yokuncibilika: 80-82 ℃
-Iphuzu elibilayo: mayelana ne-260 ℃ (ukubola)
-I-Soluble: Incibilika ku-asidi, i-alkali, i-ethanol ne-ether, inyibilika kancane emanzini.
Sebenzisa:
- I-2-Mercaptopyrazine ingasetshenziswa njengento ebalulekile emaphakathi ekuhlanganiseni kwezinto eziphilayo futhi ingadlala indima ebalulekile ekuhlanganiseni kwezidakamizwa nezibulala-zinambuzane.
-Ingasetshenziselwa ukulungisa odayi be-pyrazine, ama-intermediate emithi kanye nama-coordination compounds.
Indlela Yokulungiselela:
I-2-Mercaptopyrazine ingahlanganiswa:
1. Ukusabela kwe-2-bromopyrazine ne-sodium hydrogen sulfate emanzini/ethanol ukunikeza i-2-Mercaptopyrazine. Izimo zokusabela ngokuvamile zifana nokuthi ukusabela kushukunyiswa ekamelweni lokushisa.
2. I-2-Mercaptopyrazine ingaphinda itholakale ngokusabela i-2-chloropyrazine ne-thiol ngaphansi kwezimo ze-alkaline.
Ulwazi Lokuphepha:
- I-2-Mercaptopyrazine iyinhlanganisela ecasulayo engase ibangele ukucasuka lapho uxhumane nesikhumba, amehlo noma ngokuhogela uthuli lwayo.
-Gqoka izinto zokuzivikela ezifana namagilavu okuvikela amakhemikhali, izibuko zokuphepha namamaski okuzivikela lapho uphatha i-2-Mercaptopyrazine.
-Uma usebenzisa lesi sithako, sicela uqiniseke ukuthi usebenza endaweni enomoya omuhle ukuze ugweme ukuhogela uthuli lwayo.
-Gwema ukuthintana nama-oxidants nama-acids aqinile ukuze uvimbele ukusabela okuyingozi.
-Gcina i-2-Mercaptopyrazine esitsheni esingangeni moya, kude nemithombo yokushisa nemililo.
