Selelekela

Furoyl acetate, eo hape e tsejoang ka hore ke acetylsalicylate, ke motsoako oa lintho tse phelang. Se latelang ke selelekela sa thepa, ts'ebeliso, mekhoa ea ho lokisa le tlhaiso-leseling ea polokeho ea furfuryl acetate:

 

Boleng:

Furfuryl acetate ke mokelikeli o mosehla o mosehla o se nang 'mala o nang le monko o khethehileng. E qhibiliha ka mefuta e fapaneng ea li-solvents, tse kang joala le ethers, mocheso oa kamore.

 

Tšebeliso: E na le tatso ea litholoana tse nkhang hamonate 'me hangata e sebelisoa ho litlolo le linoko ho eketsa monko le tatso ea sehlahisoa. Furfur acetate le eona e ka sebelisoa lits'ebetsong tsa indasteri joalo ka liphahlo, polasetiki le rabara.

 

Mokhoa:

Furfur acetate ka kakaretso e lokisoa ka karabelo ea esterification, ts'ebetso e ikhethileng ke ho arabela acid e furfuric ka acetic anhydride, ho eketsa li-catalysts tsa esterification tse kang sulfuric acid kapa ammonium formate, le ho arabela ka mocheso le nako e itseng. Qetellong ea karabelo, litšila li tlosoa ke dehydration le distillation ho fumana furfuryl acetate e hloekileng.

 

Lintlha tsa Tšireletseho:

Furfuryl acetate e na le chefo e tlase, empa ho hema ka nako e telele ho ka ba le litlamorao tse mpe tsa bophelo bo botle. Furfur acetate ke mokelikeli o tukang 'me o lokela ho bolokoa hole le malakabe a bulehileng le mehloli ea mocheso o phahameng, ebe o bolokoa sebakeng se phodileng, se nang le moea o pholileng. Ela hloko mehato ea tšireletso nakong ea tšebeliso, joalo ka ho roala likhalase tse sireletsang, liatlana tse sireletsang le liaparo tse sireletsang. Haeba ho tšoloha kapa ho chefo, nka mehato e loketseng ea thuso ea pele hang-hang 'me u batle thuso ea bongaka ka nako.
