D-lactic acid ndi mankhwala. Fomula ya molekyulu ndi C3H6O3. D-lactic acid 90% ndi high optical (chiral) lactic acid opangidwa ndi ukadaulo wa biological fermentation pogwiritsa ntchito ma carbohydrate ofanana ndi shuga ngati zopangira. Chomaliza chaD-lactic asidindi madzi opanda mtundu kapena opepuka achikasu owoneka bwino okhala ndi kukoma pang'ono kowawasa; ndi hygroscopic, ndipo njira yamadzimadzi imawonetsa acidic reaction. Ikhoza kusakanikirana momasuka ndi madzi, ethanol kapena ether, ndipo imakhala yosasungunuka mu chloroform.

Amagwiritsidwa ntchito pokonza ndi kupanga zinthu za polylactic acid ndi kaphatikizidwe ka mankhwala a chiral ndi mankhwala ophera tizilombo.
Mankhwala a Chiral
Ma ester a lactic acid omwe amagwiritsa ntchito D-lactic acid monga zida zopangira amagwiritsidwa ntchito kwambiri popanga mafuta onunkhira, zokutira zopangira utomoni, zomatira ndi inki zosindikizira, komanso pakuyeretsa mapaipi amafuta ndi mafakitale amagetsi. Pakati pawo, D-methyl lactate ikhoza kusakanikirana mofanana ndi madzi ndi zosungunulira zosiyanasiyana za polar, zimatha kuthetsa nitrocellulose, cellulose acetate, cellulose acetobutyrate, etc. ndi ma polima osiyanasiyana a polar synthetic, ndipo ali ndi malo osungunuka. Ndiwosungunulira wabwino kwambiri wokhala ndi malo otentha kwambiri chifukwa cha zabwino zake za kutentha kwambiri komanso kutsika pang'onopang'ono kwa evaporation. Itha kugwiritsidwa ntchito ngati gawo la zosungunulira zosakanikirana kuti zithandizire kukhazikika komanso kukhazikika. Kuphatikiza apo, itha kugwiritsidwanso ntchito ngati zida zopangira mankhwala, mankhwala ophera tizilombo komanso zoyambira pakuphatikiza mankhwala ena a chiral. , Wapakatikati.
zinthu zowonongeka
Lactic acid ndiye zopangira za bioplastic polylactic acid (PLA). Maonekedwe azinthu za PLA zimadalira kapangidwe kake ndi zomwe zili mu D ndi L isomers. Racemate D, L-polylactic acid (PDLLA) yopangidwa kuchokera ku racemic D, L-lactic acid imakhala ndi mawonekedwe aamorphous, ndipo mawonekedwe ake amawongoleredwa ndi osauka, nthawi yowonongeka ndi yochepa, ndipo kuchepa kumapezeka m'thupi, ndi kuchepa kwa 50%. % kapena kupitilira apo, kugwiritsa ntchito kumakhala kochepa. Zigawo za L-polylactic acid (PLLA) ndi D-polylactic acid (PDLA) zimakonzedwa nthawi zonse, ndipo crystallinity yawo, mphamvu zamakina ndi malo osungunuka ndizokwera kwambiri kuposa za PDLLA.
