Isingeniso

I-Lactic acid ethyl ester iyinhlanganisela yezinto eziphilayo.

 

I-Ethyl lactate iwuketshezi olungenambala olunokunambitheka kwesithelo esidakayo ezingeni lokushisa legumbi. Incibilika kuzincibilikisi zemvelo ezifana notshwala, ama-ether, nama-aldehydes, futhi ingasabela emanzini ukuze yakhe i-lactic acid.

 

I-Ethyl lactate inokusetshenziswa okuhlukahlukene. Embonini yezinongo, ivame ukusetshenziswa njengesithako ekulungiseleleni ukunambitheka kwezithelo. Okwesibili, ku-organic synthesis, i-ethyl lactate ingasetshenziswa njenge-solvent, catalyst, kanye ne-intermediate.

 

Kunezindlela ezimbili eziyinhloko zokulungiselela i-ethyl lactate. Enye iwukusabela i-lactic acid ne-ethanol bese ibhekana ne-esterification reaction ukuze ikhiqize i-ethyl lactate. Okunye ukusabela i-lactic acid ne-acetic anhydride ukuze kutholwe i-ethyl lactate. Zombili lezi zindlela zidinga ukuba khona kwe-catalyst efana ne-sulfuric acid noma i-sulfate anhydride.

 

I-Ethyl lactate iyinhlanganisela enobuthi obuphansi, kodwa kusenezinyathelo zokuphepha okufanele zicatshangelwe. Ukuchayeka ku-ethyl lactate kungase kubangele ukucasuka kwamehlo nesikhumba, futhi izinto zokuzivikela ezifanele kufanele zigqokwe lapho uzisebenzisa. Gwema ukuchayeka emalangabi avulekile namazinga okushisa aphezulu ukuze uvimbele ukusha noma ukuqhuma. Uma usebenzisa noma ugcina i-ethyl lactate, ukunakekelwa kufanele kuthathwe ukuze kugcinwe kude nezinto ezivuthayo kanye nama-oxidizing agents. Uma i-ethyl lactate idliwe noma ihogeliwe, funa usizo lwezokwelapha ngokushesha.
