Ammonium acetate. Ulungiselela laboratory kanye indlela yezimboni. isicelo

I chemical kwakwakhe NH4C2H3O2 Ukwakheka eyaziwa emibuthanweni ububanzi njengoba ammonium acetate. Ngokubukeka kuba impahla crystalline esobala noma amhlophe. Umkhiqizo lokulungiselela salo acetic acid. Ammonium acetate kuveza ukusabela acid-ammonia. Njengoba izinto zitholakala kalula futhi kancane, lokhu kwakwakhe isetshenziswa njengophawu okufakiwe ukudla (E264) noma uyalondoloza.
Phakathi Izakhiwo imele hygroscopic. Lokho-ke anazo ammonium acetate. Ukulungiselela efana ngaphansi kwezimo zelabhorathri kungenzeka ngezindlela eziningana. Ukusabela kungaba kwenziwe nge kanzulu (glacial) acid acetic kanye carbonate ammonium (ammonium carbonate). Umphumela we-yokusabela ammonium acetate, futhi engazinzile carbonic acid, kuba isikhathi esifushane iguqulwe ibe-carbon dioxide futhi amanzi.
Eyasabela ngayo kuhilela agubhayo 80% acetic acid kuya 10% ammonia (ammonia). Ukuze ukusabela kudinga lokushisa ongaphakeme. Lehliselwa esitsheni ne ice igabha ne reactants, ngezikhathi shaking ke ngamandla. Ngu ukuhwamuka we filtrate, ammonium acetate.
Ukuze ukusabela lwesithathu usebenzisa nitrile acetic acid noma acetonitrile. Kuyinto evuthayo ngamanzi. Phakathi izindlela lokuveza isicelo zezimboni wathola ukusabela lapho ammonium acetate okulungiselelwe kusukela acetic acid ukusabela nge isixazululo ammonia aqueous.

Phakathi izindlela zokukhiqiza ammonium acetate ukusabela kungenziwa isehlane, lapho kwakwakhe ibangelwa umkhiqizo ukucutshungulwa ugodo amakhemikhali - ammonia. Kodwa injongo eyinhloko okunjena - diacylated cellulose.
Isici esiphawulekayo ammonium acetate yikhono layo ukubola ezingeni lokushisa 112 ° C acetamide namanzi. Cishe le ndlela yokusabela zivame ukuliveza njengesibonelo noqhekeko usawoti at okushisa iphansana.
Ammonium acetate elisetshenziswa umkhakha futhi ezimweni zaselebhu njengoba uketshezi ingxenye for anti-Uqweqwe. Imboni yokudla iye kwatholakala kuwo i uyakulondoloza ngempumelelo. Iphinde isetshenziselwe njengoba reagent phakathi ezinye izinhlobo zamagama organic. Laboratory umsebenzi ucwaningo ucabangela ukusetshenziswa ammonium acetate njengendlela wengxenye ye sesikhashana izixazululo namaprotheni sebethule.
I ubuchwepheshe ngokunyathelisa indwangu noma yokudweba usebenzisa ammonium acetate. Isetshenziselwa enkulu ekwakhekeni kwama-antibiotic neminye imikhiqizo abekho embonini yokwenziwa kwemithi. Futhi, sisetshenziswa kabanzi emsebenzini wokukhiqiza Foam zenjoloba, epulasitikini, vinyl.
Ukusetshenziswa ammonium acetate ngezinhloso zezimboni kudinga zokuthutha nesitorej omningi. Ngokuvamile, i-powder crystalline igcwele ngendlela ekhethekile izikhwama elukiwe noma amabhokisi iphepha. Ukuze isitoreji esetshenziswa Igumbi ezomile lapho izidakamizwa lisesimweni uphawu emaphaketheni abo yasekuqaleni. Ingqikithi akuyona ezinobuthi futhi akusho ukwethula ingozi empilweni abasebenzi. Okumele kuqashelwe lapho usingatha lolu kwakwakhe kusikisela ivikela isikhumba namehlo.
Uma into surface mucosal wokuqala nge kuyinto uhlambulule luningi ngamanzi ahlanzekile. Ngemva ukusebenza acetate ammmoniem kufanele kahle wageza ngamanzi nensipho.
Ngo umlilo mayelana kwakwakhe umbuzo ayiyona ingozi. Akukhona obhubhisayo akuyona luvutha kalula. Domestic chemical umkhakha uye kushintshwe ukukhululwa kwe izinto eziningi ezanele ukuze sihlangabezane nezidingo zokukhiqiza. Ngaphezu kwalokho, izinto zosizo ezihlukahlukene ammonium acetate abavela kwamanye amazwe. Ngokwesiko, ongenisa main futhi lapha China.
