Umkhiqizi Intengo Enhle Ammonium Chloride CAS:12125-02-9

I-Ammonium chloride, (ibanga lezimboni) I-Ammonium chloride (ebizwa ngokuthi "i-chloramine", eyaziwa nangokuthi isihlabathi se-halogen, ifomula yamakhemikhali: i-NH4Cl) iyi-cubic crystal noma i-white crystal powder engenambala. Inambitheka njengosawoti futhi ibaba kancane futhi iyingxenye kasawoti we-acid. Ubuningi bayo obuhlobene bungu-1.527. Iyancibilika emanzini, i-ethanol kanye ne-ammonia ewuketshezi kodwa ayincibiliki ku-acetone kanye ne-ether. Isixazululo samanzi sinciphile kakhulu, futhi i-acidity yaso iyakhula ngenkathi ifudumala. Uma ifudumala kufika ku-100 ° C, iqala ukuguquguquka kakhulu, futhi uma ifudumala kufika ku-337.8 ° C, izohlukana ibe yi-ammonia kanye ne-hydrogen chloride, okuthi, uma ibanda, ihlangane futhi ikhiqize izinhlayiya ezincane ze-ammonium chloride kanye nomusi omhlophe okunzima ukuwucwilisa futhi okunzima kakhulu ukuwuncibilikisa emanzini. Uma ifudumala kufika ku-350 ° C, izoncibilika futhi uma i-520 ° C, izobila. Ukumuncwa kwayo komswakama kuncane, futhi esimweni sezulu esimanzi semvula kungamunca umswakama ukuze kubhakwe. Kuzinsimbi zensimbi nezinye izinsimbi, iyabola, ikakhulukazi, enokonakala okukhulu kwethusi kodwa ayinabo ukubola kwensimbi yengulube. I-Ammonium chloride ingatholakala ekusabeleni kwe-neutralization kwe-ammonia ne-hydrogen chloride noma i-ammonia ne-hydrochloric acid (i-reaction equation: NH3 + HCl → NH4Cl). Uma ishiswa, izobola ibe yi-hydrogen chloride kanye ne-ammonia reaction (i-equation: NH4Cl → NH3 + HCl) futhi ukusabela kungakwesokudla kuphela uma isitsha sivulekile.
I-Ammonium chloride isetshenziswa kakhulu kumabhethri omile, amabhethri okugcina, usawoti we-ammonium, ukushiswa kwesikhumba, ukucwebezela, imithi, izithombe, ama-electrode, izinamathiseli, njll. I-Ammonium chloride nayo ingumanyolo wamakhemikhali we-nitrogen otholakalayo one-nitrogen engu-24% kuya ku-25%. Ungumanyolo we-acidic ophilayo futhi ofaneleka kukolweni, ilayisi, ummbila, imbewu ye-rapeseed kanye nezinye izitshalo. Inemiphumela yokuthuthukisa ukuqina kwefayibha kanye nokuxineka kanye nokuthuthukisa ikhwalithi ikakhulukazi ezitshalweni zikakotini nezelineni. Kodwa-ke, ngenxa yemvelo ye-ammonium chloride, uma ukusetshenziswa kungalungile, kuzoletha imiphumela emibi enhlabathini nasezitshalweni.
Izimo zobuchwepheshe: ukusetshenziswa kwe-People's Republic of China standard GB-2946-82 kazwelonke.
1. Ukubukeka: ikristalu elimhlophe
2. okuqukethwe kwe-ammonium chloride (isisekelo esomile) ≥ 99.3%
3. okuqukethwe komswakama ≤1.0%
4. okuqukethwe yi-sodium chloride (isisekelo esomile) ≤0.2%
5. okuqukethwe kwensimbi ≤0.001%
6. okuqukethwe kwensimbi esindayo (ngokwe-Pb) ≤0.0005%
7. okuqukethwe okungancibiliki emanzini ≤0.02%
8. okuqukethwe yi-sulfate (ngokwe-SO42-) ≤0.02%
9. i-pH: 4.2-5.8
I-Ammonium chloride isetshenziswa njengesithako esijiyile nanjengesengezo kuma-toners angewona utshwala. Ngokusho kwabakhi bezimonyo, ingxenye ye-ammonium inikeza umuzwa wokuthuthumela noma wokuhlaba abanye abantu abawuhlobanisa nama-toners noma ama-aftershaves, futhi, kuma-toners avamile, ngokuvamile anikezwa okuqukethwe utshwala. Ukusetshenziswa kwe-ammonium chloride kuwumphumela wokukhetha ekuzizweni kokwakheka.
I-Ammonium Chloride iwukudla okuphekwa ngenhlama kanye nemvubelo okukhona njengamakristalu angenambala noma i-white crystalline powder. Cishe amagremu angu-30–38 ancibilika emanzini ku-25°c. I-ph yesisombululo esingu-1% ku-25°c ingu-5.2. Isetshenziswa njengesiqinisi senhlama kanye nesithuthukisi se-flavour ezitsheni ezibhakiwe kanye nomthombo we-nitrogen wokubilisa imvubelo. Isetshenziswa futhi ezithambisweni nasezintweni zokudla. Elinye igama likasawoti yi-ammonium muriate.
Amakristalu amhlophe enziwe ngosawoti we-ammonia asebenza ku-hydrochloric acid kulandelwe yi-crystallization. I-Ammonium chloride yaziwa nangokuthi i-sal ammoniac. Njengoba incibilika emanzini nasetshwaleni, i-ammonium chloride yayisetshenziswa njenge-halide ezinqubweni eziningi, kufaka phakathi iphepha elinosawoti, iphepha le-albumen, i-albumen opaltype, kanye nezinqubo ze-gelatin emulsion.
