I-methyl acetate kanye ne-ethyl acetate yizinhlelo ezimbili ezaziwayo ezisetshenziswa kabanzi kwizimboni ezahlukahlukene ezinjengopende, ukumboza, ukunamathela kanye nemithi. Izakhiwo zazo zamakhemikhali ezihlukile kanye nokusebenza kwenza kube kubalulekile kuzinhlelo zokusebenza eziningi, ngaleyo ndlela kushayele ukufunwa kwazo emakethe.
Yaziwa ngokuhwamuka kwayo okusheshayo kanye nobuthi obuphansi, i-methyl acetate isebenza njenge-solvent ephumelelayo ye-nitrocellulose, ama-resins, nama-polymers ahlukahlukene. Ukusebenza kwayo akugcini kwi-solvent imisebenzi; Kusetshenziselwa futhi ukukhiqiza ama-methyl acetate derivatives, asetshenziswa ekwenziweni kwamakhemikhali akhethekile. Ngakolunye uhlangothi, i-ethyl acetate iyathandwa ngephunga layo elimnandi nelokuzibangela okuhle kakhulu, okwenza kube yisinqumo esithandwayo embonini yokuphuza embonini yokudla.
Izinga lalezi zinhlava zibalulekile njengoba zithinta ngqo ukusebenza komkhiqizo wokugcina. I-High Purey Methyl acetate kanye ne-ethyl acetate ibalulekile ukuze izinhlelo zokusebenza ezidinga amazinga aqinile aqinile, njengokucubungula kwemithi nokudla. Abakhiqizi baya ngokuya begxile ekukhiqizeni izixazululo ezisezingeni eliphakeme ukuze zihlangabezane nezidingo ezikhulayo zalezi zimboni.
Ngokwezintengo, zombili i-methyl acetate kanye namanani entengo e-ethyl actetate ashintshile ngenxa yezinguquko ezindlekweni ezibonakalayo eziluhlaza kanye namandla emakethe. Izitayela zentengo zithonywa yizinto ezifana namandla okukhiqiza, izinguquko zokulawula, nokushintsha okuthandwa ngumthengi. Njengokusimama kuba yinto egxile emkhakheni wamakhemikhali, imakethe ihamba kancane kancane ibheke ezinhlafunweni ezenzelwe i-bio, ezingathinta intengo nokufunwa kwe-acetates yendabuko.
Sekukonke, i-methyl acetate kanye nemakethe ye-ethyl acetate kulindeleke ukuthi ikhule, iqhutshwa ngokuguquguquka kwayo kanye nesidingo esikhulayo se-solvents esezingeni eliphakeme kuyo yonke imboni ehlukahlukene. Njengoba ukuthambekela kwemakethe kuvela, ababambiqhaza kumele bahlale bephapheme ukuze bazivumelanise nezinguquko kumanani entengo nakwabathengi ukuze baqinisekise ukuthi bagcina inzuzo yokuncintisana kule ndawo enamandla.
