Isebenzisa
I-1.Ama-reagents okuhlaziya asetshenziswa kakhulu, asetshenziselwa kakhulu ukungathathi hlangothi noma i-acidification.Izinyibilikisi ze-titration ezingenamanzi, ukulungiswa kwezixazululo ze-buffer, i-organic synthesis.Ukukhiqizwa kwezingulube, izidakamizwa, imicu ye-acetate, i-acetyl compounds, njll. Ibuye isetshenziselwe ukuncibilikisa i-phosphorus, isulfure, i-hydrohalic acid, njll. Njenge-agent emuncu, ingasetshenziswa njenge-compound seasoning, ukulungisa uviniga, ukudla okusemathinini, i-jelly. kanye noshizi, futhi uyisebenzise ngamanani afanele ngokwezidingo zokukhiqiza.Ingasetshenziswa futhi njengesithuthukisi ukunambitheka kotshwala be-koji, futhi inani elisetshenzisiwe ngu-0.1-0.3g/kg.Isetshenziswa njenge-solvent ekukhiqizeni irabha, amapulasitiki, odayi, njll. Ibuye isetshenziswe njengempahla eluhlaza yokwakhiwa kwe-vinyl acetate, i-cellulose acetate, i-menthyl acetate, izidakamizwa zezithombe, imithi, izibulala-zinambuzane nezinye izinto eziphilayo.
2.Ama-analytical reagent asetshenziswa kakhulu.Izinyibilikisi ze-Universal kanye nezincibilikisi ze-titration ezingenamanzi.Isetshenziswa ekwenzeni i-acetate, i-cellulose acetate, imithi, izingulube, ama-esters, amapulasitiki, izinongo, njll.
3.PH isilawuli senani.Ingasetshenziselwa ukulungiswa kwe-ethyl acetate, ukulungiswa kwemicu, amapende, ama-adhesives, ama-copolymer resins, njll., ukulungiswa kwe-acetic anhydride, i-chloroacetic acid, i-glycolic acid kanye ne-pickle yezimboni.
I-4.Ingasetshenziselwa ukukhethwa kwezimboni.Ukuze kulungiswe ama-fibers, ama-coatings, ama-adhesives, ama-copolymer resins, njll.
I-5.Kuyinto ebalulekile yamakhemikhali e-organic impahla eluhlaza, engakhiqiza imikhiqizo ehlukahlukene yamakhemikhali e-organic.Imboni yezemithi isetshenziselwa ukulungisa imithi eyahlukene, imboni kadayi isetshenziselwa ukwakha odayi abahlukahlukene, kanti imboni yezinto zokwenziwa isetshenziselwa ukuhlanganisa izinto ezihlukahlukene ze-polymer, okuyindawo ebalulekile yamakhemikhali e-organic.Ngaphezu kwalokho, ibuye isetshenziswe njengezincibilikisi zezimboni, ama-ejenti okushuka isikhumba, ama-coagulant erabha e-latex, izinsiza zikadayi, amakha okwenziwa, ama-chemical reagents, njll.
6.I-acetic acid ingasetshenziswa kwezinye izixazululo zokukhetha nokupholisha, ezixazululweni ezine-asidi ezibuthakathaka njengezigcinalwazi (ezifana ne-galvanizing, i-electroless nickel plating), ku-semi-bright nickel Plating electrolyte njengezithasiselo, ku-zinc, isisombululo se-cadmium passivation singathuthukisa ukunamathela. yefilimu ye-passivation, futhi evame ukusetshenziselwa ukulungisa i-pH yesisombululo esibuthakathaka se-asidi, ingasetshenziswa futhi njengesinyibilikisi kwezinye izithasiselo eziphilayo (njenge-coumarin).
I-7.Ama-reagents okuhlaziya asetshenziswa ngokuvamile, ama-solvents ajwayelekile kanye ne-non-aqueous titration solvents, i-organic synthesis, ukuhlanganiswa kwezingulube kanye nemithi.
8.Isetshenziswa ekwenzeni i-acetate, i-cellulose acetate, imithi, izingulube, ama-esters, amapulasitiki, izinongo, njll.
