Ukusetyenziswa
Enye yezinto eziphambili zokusetyenziswa kwe-acetic acid kukuveliswa kwe-acetic anhydride, i-acetate esters, kunye ne-cellulose acetate. Ezi ziphuma zisetyenziswa ngokubanzi kwishishini leengubo kwaye zinceda ekuphuhliseni umgangatho ophezulu, oqinileyo. I-acetic anhydride iyisithako esibalulekileyo kwimveliso yezinto ezigcina imithi, ngelixa i-cellulose acetate isetyenziselwa ukwenza iipeyinti, iiprimers kunye nevanishi. Ngokwamkela iimveliso ezisekelwe kwi-acetate, amashishini anokuphucula ukusebenza, ixesha elide kunye nokubhenela ngokubanzi kwezicelo zabo zokugquma.
Ngapha koko, i-acetic acid isetyenziswa ngokubanzi kwimveliso yee-acetates. I-Acetate inoluhlu olubanzi lwezicelo ezibandakanya ukusetyenziswa njenge-solvent ekwenzeni iikhemikhali ezahlukeneyo, ngokukodwa kumashishini amachiza kunye neekhemikhali ezintle. Ukongeza, inokusetyenziswa njengento ekrwada kwimveliso yokuncamathelisa, iingubo kunye neeplastiki. Iimveliso ze-acetate ziyaziwa ngokucoceka kwazo okuphezulu, ukuzinza kunye nokuguquguquka, okwenza kube lukhetho oluhle kakhulu kwiimfuno ezahlukeneyo zamashishini.
Ukongeza kwezi zicelo, i-acetic acid iyisithako esibalulekileyo kwii-reagents zohlalutyo, i-organic synthesis, kunye ne-synthesis ye-pigments kunye namayeza. Iipropathi zayo zivumela ukuba kube lula ukuphendulwa kweekhemikhali ezahlukeneyo kunye neenkqubo zokwenziwa. Inceda ukuvelisa imibala esetyenziswa kwiipeyinti, ii-inki kunye nedayi, ibanika imibala edlamkileyo nehlala ixesha elide. Ngaphaya koko, i-acetic acid isetyenziswa ekudityanisweni kweziyobisi kwaye idlala indima ebalulekileyo kuphuhliso lwamachiza aphucula umgangatho wobomi babantu kwihlabathi liphela.
Ukuqukumbela, i-acetic acid iyikhompawundi exabisekileyo yezinto eziphilayo enendawo kumashishini amaninzi. Izicelo zayo zivela kwimveliso ye-acetic anhydride, i-acetates kunye ne-cellulose acetates kwimboni yepeyinti ukuya kwi-reagents yohlalutyo, i-organic synthesis kunye ne-synthesis ye-pigments kunye namayeza. Ngeempawu zayo ezahlukeneyo kunye nemisebenzi, i-acetic acid ibonakalisa ukuba sisithako esibalulekileyo kumashishini ajonge ukuphucula iimveliso kunye neenkqubo zawo. Nangona kunjalo, kubalulekile ukuphatha i-acetic ngononophelo kuba i-corrosion kwaye inokucaphukisa.
