Amagwiritsidwa ntchito ngati utomoni wapakati komanso wopangidwa ndi mankhwala 2-Furaldehyde [98-01-1]

Dzina la mankhwala: 2-Furaldehyde

Mawu ofanana: 2-Formyl furan; 2-furanaldehyde; 2-furancarbonal; 2-furancarboxaldehyde; 2-furfural; 2-furylmethanal; alpha-Furfuraldehyde; Furfuraldehyde; Pyromucic aldehyde;

Kulemera kwa maselo: C5H4O2

Mawonekedwe: Opanda utoto mpaka ofiira - madzi a bulauni okhala ndi mafuta okhala ndi fungo la amondi

Kukhazikika: 1. Sichiwononga chitsulo, chingasungidwe mu ziwiya zachitsulo, chitsulo chofewa, mkuwa kapena aluminiyamu. Pang'onopang'ono chimasanduka bulauni mumlengalenga kapena mu kuwala, kotero chiyenera kubisika ku kuwala ndikudzazidwa ndi mpweya wosagwira ntchito kuti chisungidwe chotsekedwa. Pambuyo poti furfural yayikidwa mu mpweya, mpweya, carbon dioxide ndi nayitrogeni kwa masiku 40, kuchuluka kwa ma oxide (resinous) omwe adapangidwa kunali 1.7%, 0.3%, 0.1% ndi 0.05%, motsatana. Kuwonjezera p-hydroxydiphenylamine, diphenylamine, cadmium iodide, hydroquinone, phloroglucinol kapena β-naphthol ku furfural, kuwonjezera 0.1% kungalepheretse kukhuthala. Kuwonjezera 0.001% ~ 0.1% N-phenyl-substituted urea, thiourea kapena naphthylamine ku furfural kungalepheretse kupangika kwa resin ikatenthedwa pa 60 ~ 170℃.

2. Kapangidwe ka mankhwala: furfural ili ndi kalembedwe ka aldehyde. Mwachitsanzo, chowonjezera chingapangidwe ndi sodium bisulfite, yomwe imasungunuka kukhala furanoic acid ndikuchepetsedwa kukhala furfuryl alcohol. Furfuryl alcohol ndi furfuran formic acid zinapangidwa ndi Cannizzaro reaction mu yankho la potassium hydroxide lokhazikika. Limachita ndi potassium cyanide kupanga furoin. Limachita ndi ammonia kupanga furfuramide, limachita ndi amine kupanga Schiff base. Furfural imatenthedwa kufika 350 ~ 400℃ ndi sodium lime, kapena nickel kapena zinc oxide ndi chromium, vanadium pentaoxide ngati chothandizira imatenthedwa kufika 200℃, ndipo furan imasinthidwa. Furfural yoyengedwa ikayikidwa, chifukwa cha momwe mpweya umagwirira ntchito mumlengalenga, zochitika zingapo zovuta monga kuwola ndi polymerization zimachitika, zomwe zimapangitsa mtundu kukhala wakuda. Kutentha kapena kuwala kumatha kufulumizitsa kuwola kwake, polymerization reaction.

3. Kukhazikika Kukhazikika

4. Wothandizira okosijeni wamphamvu, maziko olimba

5. Pewani kutentha, kuwala, ndi mpweya

6. Kupopera kwa polymer kumawononga kupopera kwa polymer

1.Kuyera kwakukulu 99.0% mphindi

2. Gwiritsani ntchito mitundu yosiyanasiyana ya kukoma.

3. Tili ndi satifiketi ya ISO 9001, ISO 14001 ndi ISO22000, Tilinso ndi satifiketi ya HACCP, 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. Nthawi zambiri timatumiza chitsanzocho ndi anthu ochokera kumayiko ena monga DHL kapena Fedex. Ndi chachangu komanso chosavuta kugwiritsa ntchito.

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 (ng'oma yapulasitiki yamtundu wa chakudya, yopanda pulasitiki, lipoti la satifiketi la chipani chachitatu)

Kupaka zinthu kumatha kusinthidwa malinga ndi zosowa za makasitomala
