Isticmaalka pyrazine
Pyridazine (290-37-9) oo leh laba atamka nitrogen ee 1,2 lambar waxaa loo yaqaan pyridazine; 1,3 lambar waxaa loo yaqaan pyrimidines, labaduba waa isomers pyrazines ah. Pyrazine waa crystal aan midab lahayn, dhibic dhalaalaysa 54 ° C, dhibic karkaraya 115 ~ 116 ° C (768 mm Hg), cufnaanta dareeraha ah ee qaraabada ah 1.0311 (61/4 ° C). Waxay leedahay ur la mid ah pyridine. Waxaa lagu milmaa biyaha, ethanol, ether, iwm. Pyrazine waa saldhig aad u daciif ah. Udgoonkeedu waxay la mid yihiin pyridine, aad ayey u yar tahay in la mariyo falgallada beddelka elektrofiliga ah, waxayna aad ugu firfircoon tahay nucleophiles. Ka dib marka haydarojiin ku jira atamka kaarboonka lagu beddelo koox methyl ama halogen, haydarojiin ku jira kooxda halogen ama methyl waa firfircoon yahay. Pyrazines iyo waxyaabaha ka soo baxa waxaa lagu samayn karaa habab kala duwan.
Faa'iidada pyrazine
1. Nadiifnimo sare 99.0% daqiiqo
2. Ma jiro amar qalad ah
3. Isticmaal noocyo kala duwan oo dhadhan ah
4. Waxaan haynaa shahaadada ISO, waxaan haynaa shahaadada Xalaal iyo kosher ee badeecadan.
5. Waxaan leenahay awood weyn, sidaa darteed, badanaa waxaan leenahay waqti degdeg ah oo hogaamin ah.
6. Waxaan ku siin karnaa muunad bilaash ah oo 10g-50g ah baaritaankaaga shaybaarka.
Xidhmada pyrazine
1. Baakadda muunadda waa 20g/30g/50g dhalo kasta.
2. Baakadda yar waa 1kg /5kg /10 kg dhalo kasta.
3.25 kg durbaankiiba
Baakadaha waxaa sidoo kale loo habeyn karaa iyadoo loo eegayo baahiyaha macaamiisha
Xaaladaha kaydinta ee pyrazine:
Ku hay baakadaha shaabadaysan, ku kaydi meel hawo leh, qalalan, mugdi ah heerkul caadi ah, heerkulka ka hooseeya 20 ℃ ayaa ka wanaagsan in lagu kaydiyo.
