I-acetoneiyi-solvent evamile ye-organic, esetshenziswa kakhulu embonini yamakhemikhali, ekhemisi, epende, yokunyathelisa nakwezinye izimboni. Ine-solubility eqinile kanye nokuguquguquka okulula. I-acetone ikhona ngesimo sekristalu ehlanzekile, kodwa ezimweni eziningi ingxube yezinto, futhi izinhlobo ezintathu ze-acetone yilezi: i-acetone evamile, i-isopropyl acetate ne-butyl acetate.
i-acetone evamile iwuhlobo lwe-solvent enenhloso evamile enefomula ethi CH3COCH3. Ayinambala, nokubukeka kokuguquguquka okuphansi, uketshezi oluguquguqukayo. I-acetone evamile inohlu olubanzi lokuncibilika, olungancibilikisa izinhlobonhlobo zezinto eziphilayo nezingaphili. Ingenye yezinto zokusetshenziswa ezibaluleke kakhulu embonini ye-organic synthesis futhi iphinde ibe yindawo ebalulekile ekuhlanganiseni ezinye izinhlanganisela eziphilayo. Ngaphezu kwalokho, i-acetone evamile ibuye isetshenziswe kabanzi embonini yokunyathelisa, embonini yesikhumba, embonini yendwangu kanye nezinye izimboni.
I-isopropyl acetate iwuhlobo lwenhlanganisela ye-ester enefomula ethi CH3COOCH(CH3)2. Iwuketshezi lwe-viscous olungenambala futhi olusobala olunokuguquguquka okuphansi nokuncibilika okuhle. I-Isopropyl acetate inokuhambisana okuhle nama-resin amaningi nezingulube, futhi isetshenziswa kabanzi ekukhiqizeni amapende, izinto zokunamathisela, uyinki wokunyathelisa neminye imikhiqizo. Ngaphezu kwalokho, i-isopropyl acetate iphinde isetshenziswe njenge-solvent yefilimu ye-cellulose acetate kanye nokukhiqizwa kwe-cellulose triacetate fiber.
I-butyl acetate iwuhlobo lwenhlanganisela ye-ester enefomula ethi CH3COOCH2CH2CH3. Iwuketshezi olubonisa ngale olungenambala olunokuguquguquka okuphansi nokuncibilika okuhle. I-Butyl acetate inokuhambisana okuhle nama-resin amaningi nezingulube, futhi isetshenziswa kabanzi ekukhiqizeni amapende, izinto zokunamathisela, uyinki wokunyathelisa neminye imikhiqizo. Ngaphezu kwalokho, i-butyl acetate iphinde isetshenziswe njenge-solvent yefilimu ye-cellulose acetate kanye nokukhiqizwa kwe-cellulose triacetate fiber.
izinhlobo ezintathu ze-acetone zinezici zazo kanye nokusetshenziswa kwazo emikhakheni ehlukene. I-acetone evamile inebanga elibanzi lokuncibilika futhi isetshenziswa kabanzi ezimbonini ezahlukahlukene; I-Isopropyl acetate ne-butyl acetate inokuhambisana okuhle nama-resin nemibala futhi isetshenziswa kabanzi ekukhiqizeni amapende, izinto zokunamathisela, uyinki wokuphrinta neminye imikhiqizo. Ngaphezu kwalokho, ziphinde zisetshenziswe njengezinyibilikisi zefilimu ye-cellulose acetate kanye nokukhiqizwa kwe-fiber cellulose triacetate.
