Ukusetshenziswa kwe-pyrazine
I-Pyridazine (290-37-9) enama-athomu amabili e-nitrogen ngezinombolo ezingu-1,2 ibizwa ngokuthi i-pyridazine; Izinombolo ezingu-1,3 zibizwa ngokuthi ama-pyrimidines, futhi zombili ziyi-isomers yama-pyrazines. I-Pyrazine iyikristalu engenambala, iphuzu lokuncibilika lingu-54 ° C, iphuzu lokubila lingu-115 ~ 116 ° C (768 mm Hg), ubuningi boketshezi obuhlobene ngu-1.0311 (61/4 ° C). Inephunga elifana ne-pyridine. Incibilika emanzini, i-ethanol, i-ether, njll. I-Pyrazine iyisisekelo esibuthakathaka kakhulu. Ama-aromatic ayo afana ne-pyridine, akunakwenzeka ukuthi ibhekane nokusabela kokushintshana kwe-electrophilic, futhi isebenza kakhulu kuma-nucleophiles. Ngemva kokuba i-hydrogen e-athomu ye-carbon ithathelwe indawo yiqembu le-methyl noma i-halogen, i-hydrogen eqenjini le-halogen noma le-methyl iyasebenza. Ama-Pyrazines kanye nezinto eziphuma kuzo zingakhiwa ngezindlela ezahlukene.
Inzuzo ye-pyrazine
1. Ubumsulwa obuphezulu 99.0% min
2. Akukho ukuhleleka okubi
3. Sebenzisa ukunambitheka okubanzi
4. Sinesitifiketi se-ISO, sinesitifiketi se-Halal kanye ne-kosher salo mkhiqizo.
5. Sinamandla amakhulu, ngakho-ke, sivame ukuba nesikhathi sokuhola esisheshayo.
6. Singakunikeza isampula yamahhala engu-10g-50g yokuhlolwa kwakho kwelebhu.
Ukupakishwa kwe-pyrazine
1. Ukupakisha isampula kungu-20g/30g/50g ngebhodlela ngalinye.
2. Ukupakisha okuncane kungu-1kg /5kg /10 kg ngebhodlela ngalinye.
3.25 kg ngesigubhu ngasinye
Ukupakisha nakho kungenziwa ngezifiso ngokwezidingo zamakhasimende
Izimo zokugcina i-pyrazine:
Gcina ukupakisha kuvaliwe, kugcinwe endaweni enomoya, eyomile, emnyama ekushiseni okuvamile, izinga lokushisa elingaphansi kuka-20 ℃ lizoba ngcono ekugcinweni.
