Acide D-lactique ni imiti. Inzira ya molekile ni C3H6O3. Acide D-lactique 90% ni aside irike ya optique (chiral) yakozwe na tekinoroji ya fermentation ya biologiya ikoresheje karubone ya hydrata isa nisukari nkibikoresho fatizo. Igicuruzwa cyarangiye cya D-lactique ni ibara ritagira ibara cyangwa ryijimye ry'umuhondo risukuye rifite uburyohe busharira; ni hygroscopique, kandi igisubizo cyamazi cyerekana aside irike. Irashobora kuvangwa kubuntu namazi, Ethanol cyangwa ether, kandi ntigishobora gukomera muri chloroform.

Ikoreshwa cyane cyane mugutunganya no gukora ibikoresho bya aside polylactique hamwe no guhuza imiti ya chiral hamwe nabahuza imiti yica udukoko.
Imvange ya Chiral
Acide ya Lactique ikoresha aside D-lactique nkibikoresho fatizo bikoreshwa cyane mugukora parufe, ibishishwa bya resinike, ibifata hamwe na wino yo gucapa, ndetse no mugusukura imiyoboro ya peteroli ninganda za elegitoroniki. Muri byo, L-lactate ya D-methyl irashobora kuvangwa neza hamwe namazi hamwe nudukoko twinshi twa polar, irashobora gushonga byimazeyo nitrocellulose, selile acetate, selile acetobutyrate, nibindi hamwe na polimeri zitandukanye za polarike, kandi bifite aho bishonga. Numuti mwiza cyane utetse cyane kubera ibyiza byubushyuhe bwo hejuru hamwe nigipimo cyuka buhoro. Irashobora gukoreshwa nkibigize imvange ivanze kugirango itezimbere imikorere na solubilisation. Byongeye kandi, irashobora kandi gukoreshwa nkibikoresho fatizo byimiti, imiti yica udukoko nimbanzirizamushinga yo guhuza ibindi bintu bya chiral. Hagati.
ibikoresho byangirika
Acide Lactique ni ibikoresho fatizo bya aside bioplastique polylactique (PLA). Imiterere yumubiri wibikoresho bya PLA biterwa nibigize nibirimo D na L. Irushanwa rya D, L-polylactique (PDLLA) ikomatanyirijwe mu bwoko bwa D, aside L-lactique ifite imiterere ya amorphous, kandi imiterere yayo ya mashini irakennye, igihe cyo kwangirika ni gito, kandi kugabanuka kugaragara mu mubiri, hamwe no kugabanuka kwa 50%. % cyangwa byinshi, gusaba ni bike. Ibice by'urunigi bya L-polylactique (PLLA) na D-polylactique aside (PDLA) bitunganijwe buri gihe, kandi kristu, imbaraga za mashini hamwe no gushonga biri hejuru cyane ugereranije na PDLLA.
