Intshayelelo

I-Lactic acid ethyl ester yi-organic compound.

 

I-Ethyl lactate lulwelo olungenambala kunye nencasa yeziqhamo ezinxilisayo kubushushu begumbi. Iyanyibilika kwii-solvents eziphilayo ezifana ne-alcohol, i-ethers, kunye ne-aldehydes, kwaye inokusabela ngamanzi ukwenza i-lactic acid.

 

I-Ethyl lactate ineendlela ezahlukeneyo zokusetyenziswa. Kushishino lweziqholo, isoloko isetyenziswa njengesithako ekulungiseleleni incasa yeziqhamo. Okwesibini, kwi-organic synthesis, i-ethyl lactate ingasetyenziselwa njenge-solvent, i-catalyst, kunye ne-intermediate.

 

Kukho iindlela ezimbini eziphambili zokulungiselela i-ethyl lactate. Enye kukusabela i-lactic acid kunye ne-ethanol kwaye i-esterification reaction ivelise i-ethyl lactate. Enye kukusabela i-lactic acid kunye ne-acetic anhydride ukufumana i-ethyl lactate. Zombini ezi ndlela zifuna ubukho be-catalyst efana ne-sulfuric acid okanye i-sulfate anhydride.

 

I-Ethyl lactate yikhompawundi enetyhefu ephantsi, kodwa kusekho imiqathango yokhuseleko ekufuneka ithathelwe ingqalelo. Ukuvezwa kwi-ethyl lactate kunokubangela ukucaphuka kwamehlo kunye nolusu, kwaye izixhobo ezifanelekileyo zokukhusela kufuneka zinxitywe xa uyisebenzisa. Kuphephe ukuba sesichengeni samadangatye avulekileyo kunye namaqondo obushushu aphezulu ukuthintela ukutsha okanye ugqabhuko-dubulo. Xa usebenzisa okanye ugcina i-ethyl lactate, kufuneka kuthathelwe ingqalelo ukuyigcina kude nezinto ezinokutsha kunye ne-oxidizing agents. Ukuba i-ethyl lactate ityiwe okanye irhoxiwe, funa unyango ngokukhawuleza.
