Te Whakamahinga o te Pyrazine
Ko te Pyridazine (290-37-9) me ngā ngota hauota e rua i roto i te 1,2 mati ka kiia ko te pyridazine; ko ngā mati 1,3 ka kiia ko ngā pyrimidine, ā, he isomers rāua o ngā pyrazine. He karaihe kore tae te Pyrazine, ko te ira rewa he 54 ° C, ko te ira kohua he 115 ~ 116 ° C (768 mm Hg), ko te kiato whanaunga wai he 1.0311 (61/4 ° C). He kakara rite ki te pyridine. Ka wairewa ki te wai, te etanoru, te etera, me ētahi atu. He turanga ngoikore rawa te Pyrazine. He rite ōna kakara ki te pyridine, he iti rawa te tūponotanga ka pāngia e ngā tauhohenga whakakapinga hiko, ā, he kaha ake ki ngā nucleophile. I muri i te whakakapinga o te hauwai i runga i te ngota waro ki te rōpū methyl, halogen rānei, ka kaha te hauwai i runga i te halogen, i te rōpū methyl rānei. Ka taea te hanga i ngā Pyrazine me ō rātou hua mā te maha o ngā tikanga.
Ngā painga o te pyrazine
1. Teitei te parakore 99.0% min
2. Kāore he ota hē
3. Whakamahia he whānuitanga o ngā reka
4. Kei a mātou te tiwhikete ISO, te tiwhikete Halal me te tiwhikete Kosher mō tēnei hua.
5. He nui tō mātou kaha, nō reira, he tere te wā arahi.
6. Ka taea e mātou te tuku tauira kore utu 10g-50g mō tō whakamātautau taiwhanga.
Te tākai o te pyrazine
1. Ko te taumaha o te tauira he 20g/30g/50g mō ia pounamu.
2. Ko te taumaha o te tākai iti he 1kg /5kg /10 kg mō ia pounamu.
3.25 kg ia pahu
Ka taea hoki te whakarite i te takai kia rite ki ngā hiahia o te kiritaki
Ngā tikanga rokiroki mō te pyrazine:
Puritia te takai kia hiritia, rongoatia ki te wāhi hauhautanga, maroke, pōuriuri i te pāmahana noa, he pai ake te penapena ki te pāmahana i raro iho i te 20 ℃.
