Ukusetyenziswa kwe-pyrazine
I-Pyridazine (290-37-9) eneeathom ezimbini ze-nitrogen kwiidijithi ezili-1,2 ibizwa ngokuba yi-pyridazine; Iidijithi ezili-1,3 zibizwa ngokuba yi-pyrimidines, kwaye zombini ziyi-isomers ze-pyrazines. I-Pyrazine yikristale engenambala, iqondo lokunyibilika liyi-54 ° C, iqondo lokubila liyi-115 ~ 116 ° C (768 mm Hg), uxinano lolwelo luyi-1.0311 (61/4 ° C). Inevumba elifana ne-pyridine. Inyibilika emanzini, kwi-ethanol, kwi-ether, njl. I-Pyrazine sisiseko esibuthathaka kakhulu. Ii-aromatics zayo zifana ne-pyridine, akunakwenzeka ukuba ifumane ii-electrophilic substitution reactions, kwaye isebenza ngakumbi kwi-nucleophiles. Emva kokuba i-hydrogen kwi-atom yekhabhoni ithatyathelwe indawo liqela le-methyl okanye i-halogen, i-hydrogen kwi-halogen okanye kwiqela le-methyl iyasebenza. Ii-Pyrazines kunye ne-derivatives zazo zinokwenziwa ngeendlela ezahlukeneyo.
Inzuzo ye-pyrazine
1. Ubunyulu obuphezulu 99.0% min
2. Akukho myalelo ungalunganga
3. Sebenzisa uluhlu olubanzi lweencasa
4. Sinesatifikethi se-ISO, sinesatifikethi seHalal kunye nesekosher sale mveliso.
5. Sinomthamo omkhulu, ngoko ke, sihlala sinexesha elikhawulezayo lokuqalisa.
6. Singakunika isampuli yasimahla ye-10g-50g kuvavanyo lwakho lwelebhu.
Ukupakishwa kwe-pyrazine
1. Ukupakisha isampuli yi-20g/30g/50g kwibhotile nganye.
2. Ukupakisha okuncinci yi-1kg /5kg /10 kg kwibhotile nganye.
3.25 kg ngedrama nganye
Ukupakisha kungenziwa ngokwezifiso ngokweemfuno zabathengi
Iimeko zokugcina i-pyrazine:
Gcina ukupakisha kuvaliwe, kugcinwe kwindawo enomoya, eyomileyo, emnyama kubushushu obuqhelekileyo, ubushushu obungaphantsi kwama-20 ℃ buya kuba ngcono xa bugcinwa.
