I-acetic acid ye-glacial yezinga lezimboni engu-99.8% (CAS 64-19-7, UN 2789, ifomula yamakhemikhali i-CH₃COOH) iphakathi kwezinto ezibaluleke kakhulu ezisetshenziswa ekukhiqizeni kwamakhemikhali emhlabeni jikelele kwanamuhla. Lo mkhiqizo uketshezi olungenambala olunephunga elicasulayo eliphawulekayo, oluthengiswa kabanzi kuzo zonke iziteshi zamakhemikhali zomhlaba wonke kuma-drum angu-30 kg, ama-drum angu-215 kg kanye namathangi e-IBC ukuze kusetshenziswe izinto eziningi ngendlela eguquguqukayo.

Idatha yakamuva yemboni iqokomisa izinguquko eziphawulekayo ze-glacial acetic acid evela eShayina ngo-2026. Kusukela ngoJanuwari kuya kuJulayi, inani lokuthunyelwa kwamanye amazwe kwe-glacial acetic acid eShayina lenyuke ngo-32.95% unyaka nonyaka, kuyilapho inani lokungeniswa kwamanye amazwe lehla kakhulu, okubonisa inzuzo yokuncintisana ekhulayo yaseShayina ekuhlinzekweni kwe-glacial acetic acid emhlabeni jikelele. Amashejuli okugcinwa kwezitshalo zaphesheya kwezilwandle aqinile, izindleko zamandla eziphezulu zesifunda kanye nokusetshenziswa okuzinzile kwamandla asekhaya ndawonye kusunduza i-glacial acetic acid engu-99.8% yobumsulwa obuphezulu ukuthi igeleze iye eNingizimu-mpumalanga ye-Asia, eMpumalanga Ephakathi nakwezinye izindawo zokukhiqiza zaphesheya kwezilwandle.

Njengekhemikhali yokwakha eyisisekelo, i-glacial acetic acid engu-99.8% isekela izintambo eziningi zezimboni ezingezansi. Isebenza njenge-feedstock eyinhloko yokukhiqiza i-vinyl acetate monomer, i-acetic anhydride, ama-ester ahlukahlukene e-acetate kanye nemikhiqizo ye-cellulose acetate, eqhubeka nokudla izimboni zokumboza, zokunamathisela kanye nezokupakisha. Ngaphakathi kwemikhakha yamakhemikhali amahle, ibamba iqhaza ekwakhiweni kwe-diethyl malonate, i-ethyl acetoacetate kanye nohlu olubanzi lwama-acetate salts. Iphinde idlale indima engenakuphikwa ekukhiqizeni imikhiqizo yemithi kufaka phakathi i-aspirin, kanye nezinto zokusetshenziswa zamakhemikhali okubulala izinambuzane, odayi kanye nezithombe. Ngaphandle kwalokho, amafektri okudaya izindwangu asebenzisa i-glacial acetic acid ukulungisa inani le-pH lokudaya izindwangu ngokulinganayo, futhi abakhiqizi berabha bayisebenzisa njenge-ejenti yokucubungula ebalulekile ekukhiqizeni irabha.

Kubathengi bezimboni zomhlaba wonke, ukuthobela umkhiqizo kubalulekile. Njengoba iphawulwe njengezimpahla eziyingozi ze-UN 2789, i-glacial acetic acid idinga ukupakishwa okujwayelekile kanye nokuphathwa okuqinile kwezokuthutha. Abaphakeli abathembekile banikeza i-glacial acetic acid esezingeni elizinzile engu-99.8% enemibhalo ephelele ehlanganisa ikhodi ye-HS 29152119, amaphepha edatha yokuphepha kanye nedatha yokucaciswa kokulayisha (amathani angu-22.2 ngama-drum angu-30 kg, amathani angu-17.2 ngama-drum angu-215 kg, amathani angu-21 ngamathangi e-IBC). Ngaphansi kwesimo samanani aguqukayo ezinto zokusetshenziswa zamakhemikhali emhlabeni jikelele, i-glacial acetic acid efanelekile yezinga lezimboni enokuhlanzeka okuqhubekayo ihlala iyinhloso yokuthenga ebaluleke kakhulu yokwenziwa kwamakhemikhali, ukucubungula imithi kanye namabhizinisi ezindwangu emhlabeni jikelele.
