Mawu Oyamba

Lactic acid ethyl ester ndi organic pawiri.

 

Ethyl lactate ndi madzi opanda mtundu okhala ndi zakumwa zoledzeretsa zomwe zimatentha kutentha. Amasungunuka mu zosungunulira za organic monga ma alcohols, ethers, ndi aldehydes, ndipo amatha kuchitapo kanthu ndi madzi kupanga lactic acid.

 

Ethyl lactate ili ndi ntchito zosiyanasiyana. M'makampani opangira zonunkhira, nthawi zambiri amagwiritsidwa ntchito ngati chophatikizira pokonza zokometsera za zipatso. Kachiwiri, mu kaphatikizidwe ka organic, ethyl lactate itha kugwiritsidwa ntchito ngati zosungunulira, zosungunulira, komanso zapakatikati.

 

Pali njira ziwiri zazikulu zopangira ethyl lactate. Chimodzi ndikuchita lactic acid ndi ethanol ndikukumana ndi esterification reaction kuti apange ethyl lactate. Wina ndikuchita lactic acid ndi acetic anhydride kuti apeze ethyl lactate. Njira zonsezi zimafuna kukhalapo kwa chothandizira monga sulfuric acid kapena sulfate anhydride.

 

Ethyl lactate ndi mankhwala otsika kawopsedwe, koma pali njira zina zodzitetezera zomwe ziyenera kuganiziridwa. Kuwonetsedwa kwa ethyl lactate kumatha kuyambitsa kuyabwa kwamaso ndi khungu, ndipo zida zoyenera zodzitetezera ziyenera kuvala mukamagwiritsa ntchito. Pewani kuyatsidwa ndi malawi otseguka komanso kutentha kwambiri kuti mupewe kuyaka kapena kuphulika. Mukamagwiritsa ntchito kapena kusunga ethyl lactate, chisamaliro chiyenera kutengedwa kuti chitetezeke ku zinthu zoyaka moto ndi oxidizing agents. Ngati ethyl lactate yalowetsedwa kapena kulowetsedwa, pitani kuchipatala mwamsanga.
