(r) -lactate ndi CAS 10326-41-7
(R) -Lactate CAS 10326-41-7 ndi mankhwala. Fomula ya molekyulu ndi C3H6O3. (R) -Lactate 90% ndi high optical (chiral) lactic acid yopangidwa ndi biological fermentation technology pogwiritsa ntchito ma carbohydrate ofanana ndi shuga monga zopangira. Chomalizidwa cha D-lactic acid ndi madzi opanda mtundu kapena opepuka achikasu owoneka bwino okhala ndi kukoma kowawa pang'ono; 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 zida za polylactic acid ndi kaphatikizidwe ka mankhwala a chiral ndi mankhwala ophera tizilombo.
Mankhwala a Chiral
Lactic acid esters pogwiritsa ntchito (R) -Lactate monga zopangira zimagwiritsidwa 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). Zomwe zimapangidwa ndi zinthu 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 ili ndi mawonekedwe aamorphous, ndipo makina ake 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.
