Kushandiswa kwePyrazine
Pyridazine (290-37-9) ine maatomu maviri enitrogen mu1,2 manhamba inonzi pyridazine; 1,3 manhamba anonzi pyrimidines, uye ese ari maviri isomers epyrazines. Pyrazine haina ruvara rwekristaro, inonyunguduka 54 ° C, inofashaira 115 ~ 116 ° C (768 mm Hg), density yemvura 1.0311 (61/4 ° C). Ine hwema hwakafanana nepyridine. Inonyunguduka mumvura, ethanol, ether, nezvimwewo. Pyrazine ibase isina simba. Aromatics yayo yakafanana nepyridine, hazviite kuti iite electrophilic substitution reactions, uye inoshanda zvakanyanya kune nucleophiles. Mushure mekunge hydrogen iri paatomu yekabhoni yatsiviwa ne methyl group kana halogen, hydrogen iri pahalogen kana methyl group inoshanda. Pyrazines nezvimwe zvinobva mairi zvinogona kugadzirwa nenzira dzakasiyana-siyana.
Kubatsira kwepirazine
1.Kuchena kwakanyanya 99.0% min
2. Hapana kurongeka kwakashata
3. Shandisa zvakasiyana-siyana zvekunakirwa
4. Tine chitupa cheISO, tine chitupa cheHalal nekosher chechigadzirwa ichi.
5. Tine mukana mukuru, saka, tinowanzova nenguva yekukurumidza.
6. Tinogona kupa 10g-50g sampuro yemahara yebvunzo yenyu yerabhoritari.
Kurongedza kwepirazine
1. Kurongedza kwemuenzaniso i20g/30g/50g pabhodhoro.
2. Chikafu chidiki ichi chinorema 1kg /5kg /10 kg pabhodhoro.
3.25 kg padhiramu rimwe nerimwe
Kurongedza kunogonawo kugadziriswa zvichienderana nezvinodiwa nevatengi
Mamiriro ekuchengetera pyrazine:
Chengeta zvinhu zvako zvakavharwa, zvichengeterwe munzvimbo ine mhepo inofefetera, yakaoma, ine rima munzvimbo inodziya, tembiricha iri pasi pe20 ℃ ichave iri nani pakuichengeta.
