Warshadaha Kiimikada Ammonium Acetate La Isticmaalay

Macluumaadka Alaabta

Guryaha Ammonium Acetate, Isticmaalka iyo Guudmarka Habka Wax-soosaarka
Ammonium acetate waa nooc ka mid ah Acetate Warshadaha.
Nadiifinta kiimikada NH4C2H3O2; miisaanka kelli 77.08; crystal cad; barta dhalaalka 114 ℃; cufnaanta qaraabada 1.17; heerkulka sare iyo biyaha kulul oo burburay.
Ku milmay ethanol, ku milmay biyaha, wax yar ku milmay acetone. Way fududahay in lagu lumiyo ammonia hawada. Waxaa soo saaray iyadoo la nadiifinayo acetic acid leh ammonia iyo uumi-baxa iyo crystallization xalka.
Codsiga Ammonium Acetate
Waxaa loo isticmaalaa diyaarinta bakhaarrada, go'aaminta aluminium iyo birta. Kala soocida sulfate-ka rasaasta iyo sulfate-yada kale. Waxa kale oo loo istcimaalaa sidii reagent gorfaynta, reagent chromatographic iyo baffer. Waxa kale oo loo isticmaalaa ilaalinta hilibka, electroplating, daaweynta biyaha, daawooyinka, iwm.
Ammonium acetate (ammonium acetate) sida reagents analytical, diuretics, buffers iyo loo isticmaalo rinjiyeynta iyo warshadaha daabacaadda.1) nadiifinta chymotrypsin, oo lagu garto chymotrypsin cayriin (walx firfircoon oo ka yar 10%) at 5-15 ℃, oo leh ammonium acetate xalalka iyo xalalka organic, ugu dambeyntii fuuqbaxa leh acetone chymotrypsin intermediate.2) nadiifinta urocortin, oo lagu gartaa sheyga cayriin ee urotensin (walaxda firfircooni waxay ka yar tahay 10%) waxaa lagu soo saaraa xal ammonium acetate heerkul hooseeya, oo lagu sii daayo ethanol, iyo ugu dambeyntii fuuqbaxa acetone si loo helo alaabta urotensin ee la nadiifiyey.
Diyaarinta ammonium acetate
Nidaam cusub oo loogu talagalay isku-darka nadiifinta sare ee biyaha hoose ee ammonium acetate (ammonium acetate), oo ay ku jiraan tallaabooyinka soo socda: (1) 240-250KG oo nadiif ah glacial acetic acid (nadiifinta 99.6%) galay reactor, ku dar wakiilka fuuqbaxa (wakiilada fuuq-baxa ee xeryahooda ay ku jiraan carbonyl group) 10-50 ±
(2) Marka la walaaqayo, si tartiib ah ugu dar 100-110 kg ee ammonium carbonate (nadiifinta 99.9%), milaan, iyo shaandhooyin kulul;
(3) Shaandhaynta ayaa la qaboojiyey ilaa 35 ± 5 ° C waxaana lagu hayaa 4h;
(4) Daadinta kirismaska;
(5) Rux crystallization-ka, leexashada hoosteeda, buufin adigoo ku daraya 10-30kg wakiilka fuuq-baxa (wakiilada fuuq-baxa waa xarun ka kooban karbonyl), rux qallaji;
(6) Karistalization ee ruxidda mar kale, faakuum qallajinta wareega 45 ± 5 ℃, 0.5-1h.

Macluumaadka shirkadda

Waxyaalaha ay shirkadu soo dejiso iyo wax-soo-saarka dhoofinta ugu badan waxaa ka mid ah

(1) Alaabta caagga ah : Marka alaabta caagga ah la qaabeeyo, ka dib marka lagu cadaadiyo cadaadiska sare, isku-xidhka elastomer lama baabi'in karo, taas oo inta badan soo saarta hoos u dhac aan xasilloonayn marka badeecada laga soo saaro caaryada (heerka yaraynta caaggu wuu kala duwan yahay iyadoo ku xiran nooca caag), kaas oo kaliya la fududeyn karo oo la xasilin karo wakhti go'an ka dib. Sidaa darteed, marka naqshadaynta alaabta caag ah ee bilawga, iyada oo aan loo eegin caanaha ama caaryada, waxay u baahan yihiin in si taxadar leh loo xisaabiyo si ay u dhigmaan, haddii kale, way sahlan tahay in la soo saaro cabbirka alaabta aan degganeyn, taasoo keentay tayada alaabta hooseysa.

(2) Batroolka: Wax soo saarka batroolka waa erey guud oo loogu talagalay noocyo kala duwan oo badeecado ah oo si toos ah looga soo saaro batroolka ama qayb ka mid ah batroolka. Mid ka mid ah hababka sifaynta, dildilaaca catalytic, waa isticmaalka kulaylka, cadaadiska iyo kicinta si loo jejebiyo saliidaha culus ee saliidaha fudud, badiba shidaalka. Habka kale ee sifaynta waa polymerisation, taas oo ka soo horjeeda dildilaaca: molecules yaryar ayaa lagu farsameeyaa kuwa waaweyn, iyo gaaska khafiifka ah ee sifaynta ayaa lagu dhejiyaa batroolka iyo dareeraha kale. Kiimikooyinkayada batroolka waxaa ka mid ah saliidaha iyo dufanka gaarka ah, waxyaabaha lagu daro batroolka, waxes batroolka iyo wixii la mid ah.
