| Mndandanda wa Kusinthasintha | 1.503 |
| Mkhalidwe wosungira | Malo oyaka moto |
| Kukhazikika | Yokhazikika. Yoyaka kwambiri. Yosagwirizana ndi ma acid, zinthu zopangitsa kuti zinthu ziwonjezeke. |
| Kusungunuka kwa Madzi | SULUKITSA |
Fomula yopangira kapangidwe kake:
Chitsanzo cha Masheya ndi chaulere ndipo chikupezeka
Dzina la mankhwala: pyrazine
Mawu ofanana: pyrazine
Kulemera kwa maselo: C4H4N2
Mawonekedwe: Choyera mpaka chachikasu cholimba
Kukhazikika: Kokhazikika. Koyaka kwambiri. Kosagwirizana ndi ma acid, zinthu zopangitsa kuti zinthu ziwonongeke.
Mafotokozedwe a pyrazine
| Maonekedwe | Cholimba choyera mpaka chachikasu | Woyenerera |
| Chiyero | ≥98% | 99.9% |
| Malo osungunuka | 49.5-53.5℃ | 50.4-51.3℃ |
| Fungo | Kuwawa kwamphamvu, makeke onunkhira bwino | Woyenerera |
| Moyo wa Shelufu | Chaka chimodzi chifukwa cha phukusi losatsegulidwa | |
Kugwiritsa Ntchito Pirazine
Pyridazine (290-37-9) yokhala ndi maatomu awiri a nayitrogeni m'madigito 1,2 imatchedwa pyridazine; Madigito 1,3 amatchedwa pyrimidines, ndipo onse ndi ma isomer a pyrazines. Pyrazine ndi kristalo yopanda mtundu, malo osungunuka 54 ° C, malo owira 115 ~ 116 ° C (768 mm Hg), kuchuluka kwamadzimadzi 1.0311 (61/4 ° C). Ili ndi fungo lofanana ndi pyridine. Imasungunuka m'madzi, ethanol, ether, ndi zina zotero. Pyrazine ndi maziko ofooka kwambiri. Mafuta ake onunkhira amafanana ndi pyridine, sizingatheke kuti achite zinthu zosinthira zamagetsi, ndipo amagwira ntchito kwambiri ndi ma nucleophiles. Hydrogen yomwe ili pa atomu ya kaboni ikasinthidwa ndi gulu la methyl kapena halogen, hydrogen yomwe ili pa gulu la halogen kapena methyl imagwira ntchito. Ma Pyrazines ndi zotumphukira zawo zimatha kupangidwa ndi njira zosiyanasiyana.
Ubwino wa pyrazine
1.Kuyera kwakukulu 99.0% mphindi
2. Palibe dongosolo lolakwika
3. Gwiritsani ntchito mitundu yosiyanasiyana ya kukoma
4. Tili ndi satifiketi ya ISO, tili ndi satifiketi ya Halal ndi kosher ya chinthu ichi.
5. Tili ndi mphamvu zambiri, choncho nthawi zambiri timakhala ndi nthawi yofulumira yoperekera zinthu.
6. Tikhoza kupereka chitsanzo chaulere cha 10g-50g pa mayeso anu a labu.
Kupaka kwa pyrazine
1. Kulongedza kwa chitsanzo ndi 20g/30g/50g pa botolo lililonse.
2. Kulongedza kochepa ndi 1kg /5kg /10 kg pa botolo lililonse.
3.25 kg pa ng'oma imodzi
Kupaka zinthu kumatha kusinthidwa malinga ndi zosowa za makasitomala
Mikhalidwe yosungira pyrazine:
Sungani zonyamulazo zitatsekedwa, zosungidwa pamalo opumira mpweya, ouma, amdima kutentha kwabwinobwino, kutentha kochepera 20 ℃ kudzakhala bwino kusungirako.
