Selelekela

Lactic acid ethyl ester ke motsoako oa manyolo.

 

Ethyl lactate ke mokelikeli o se nang 'mala o nang le tatso ea litholoana tse tahang mochesong oa kamore. E qhibiliha ka har'a metsoako ea tlhaho e kang alcohols, ethers le aldehydes, 'me e khona ho itšoara ka metsi ho etsa lactic acid.

 

Ethyl lactate e na le lisebelisoa tse fapaneng. Ka indasteri ea linoko, hangata e sebelisoa e le motsoako oa ho lokisa tatso ea litholoana. Taba ea bobeli, ho organic synthesis, ethyl lactate e ka sebelisoa e le solvent, catalyst, and intermediate.

 

Ho na le mekhoa e 'meli ea mantlha ea ho lokisa ethyl lactate. E 'ngoe ke ho arabela lactic acid ka ethanol le ho etsa esterification reaction ho hlahisa ethyl lactate. E 'ngoe ke ho arabela lactic acid le acetic anhydride ho fumana ethyl lactate. Mekhoa ena ka bobeli e hloka ho ba teng ha catalyst e kang sulfuric acid kapa sulfate anhydride.

 

Ethyl lactate ke motsoako oa chefo e tlase, empa ho ntse ho e-na le mehato ea tšireletso e lokelang ho nkoa. Ho pepesetsoa ethyl lactate ho ka baka ho teneha ha mahlo le letlalo, 'me ho lokela ho apesoa lisebelisoa tse nepahetseng tsa ts'ireletso ha u e sebelisa. Qoba ho pepesehela malakabe a bulehileng le mocheso o phahameng ho thibela ho tuka kapa ho phatloha. Ha u sebelisa kapa u boloka ethyl lactate, tlhokomelo e lokela ho nkoa ho e boloka hole le lintho tse tukang le li-oxidizing agents. Haeba ethyl lactate e kenngoa kapa e hema, batla thuso ea bongaka hang-hang.
