amakuru

(R) -Gusobanura, CAS nimero ni 10326-41-7. Ifite kandi aliase zimwe na zimwe, nka (R) -2-hydroxypropionic aside, D-2-hydroxypropionic aside, nibindi. Imiterere ya molekile yayo irangwa no kuba aside ya lactique ari molekile ntoya ya chiral muri kamere. Atome ya karubone kuri α umwanya witsinda rya carboxyl muri molekile ni atome idasanzwe ya karubone ifite ibishushanyo bibiri, L (+) na D (-), na aside D-lactique hano ni iburyo. (R) -Lactate ifite imiti isanzwe ya acide monocarboxylic. Igisubizo cyamazi yacyo ni acide nkeya. Iyo kwibumbira hamwe bigeze hejuru ya 50%, bizakora igice cya anhydride ya lactique, gikore hamwe nibintu bimwe na bimwe byinzoga kugirango bibe alkyd resin, kandi birashobora gukorerwa esterifike hagati yimiterere yubushyuhe kugirango habeho aside ya lactyl lactyl (C₆H₁₀O₅). Irashobora gushiramo hydrolyz muri D-lactique nyuma yo kuyungurura no gushyushya. Byongeye kandi, mugikorwa cya dehydrating agent zinc oxyde, molekile ebyiri za (R) -Lactate ikuraho molekile ebyiri zamazi hanyuma ikiyitirira polymerize kugirango ikore cyclic dimer D-lactide (C₆H₈O₄, DLA), ishobora gukora polymerized (R) -Gukora nyuma yo kubura umwuma uhagije. Kubera ko aside irike yibanda cyane, niko irushaho gukomera kwifata, aside ya lactique ikunze kuvangwa na acide lactique na lactide.

(R)-Kora igaragara nkibara ritagira ibara ryumuhondo risobanutse neza amazi yubushyuhe bwicyumba hamwe nigitutu. Impumuro nziza kandi ni hygroscopique. Igisubizo cyamazi yacyo kizerekana aside irike. Ifite imbaraga nziza kandi irashobora kuvangwa namazi, Ethanol cyangwa ether uko bishakiye, ariko ntishobora gushonga muri chloroform. Ukurikije ibipimo bifatika, ubucucike bwayo (20/20 ℃) buri hagati ya 1,20 ~ 1.22g / ml, aho gushonga ni 52.8 ° C, aho itekera ni 227,6 ° C, umuvuduko wumwuka wacyo ni 3.8Pa kuri 25 ℃, aho urumuri rwayo ni 109.9 ± 16.3 ° C, igipimo cyacyo cyo kwangirika ni nka 1.451, naho uburemere bwa molekile ni hafi ya 90.0.

(R) -GusobanuraURUBANZA10326-41-7 ikwiriye kubikwa ahantu hakonje kandi humye, kandi igomba kubikwa kure yumucyo. Ntibikwiye kubikwa hanze. Muri icyo gihe, igomba kubikwa kure y’ibintu bikomeye bya alkaline na okiside ikomeye kugira ngo ihamye kandi itume ibikwa neza kandi ikoreshwa.

Gukoresha cyane aside D-lactique

Urwego rwubuvuzi

(R) -Gusobanura URUBANZA10326-41-7 ifite akamaro gakomeye ko gusaba murwego rwubuvuzi. Nibikoresho byingenzi cyangwa intera yo guhuza imiti myinshi. Nka chiral center, (R) -Gukora URUBANZA10326-41-7 hamwe nubuziranenge bwa optique (hejuru ya 97%) niyo ibanziriza ibintu byinshi bya chiral kandi bigira uruhare rukomeye mubikorwa bya farumasi. Kurugero, irashobora gukoreshwa mugukora calcium antagonist imiti igabanya ubukana, igira ingaruka nziza mukugenzura hypertension. Mugukora kuri sisitemu yumutima nimiyoboro y'amaraso, ifasha kugabanya umuvuduko wamaraso kandi igatanga inkunga ikomeye yo kuvura abarwayi ba hypertension.

Inganda zikora imiti

(R) -GusobanuraURUBANZA10326-41-7 igira uruhare runini mu nganda zikora imiti. Amashanyarazi ya acide yakozwe na (R) -Gukora nezaURUBANZA10326-41-7 nkibikoresho fatizo bikoreshwa cyane mugikorwa cyo gukora ibicuruzwa byinshi byimiti nkimpumuro nziza, ibishishwa bya resinike, ibifatika hamwe na wino yo gucapa.

Ibikoresho bitesha agaciro

Acide D-lactiqueni ibikoresho byingenzi kuri acide bioplastique polylactique (PLA), ifite akamaro kanini mugutezimbere ibikoresho byangirika. Acide Polylactique, nkubwoko bushya bwibinyabuzima bishingiye ku binyabuzima kandi bishobora kuvugururwa, bikozwe mu bikoresho fatizo bya krahisi byakuwe mu mutungo w’ibihingwa ushobora kuvugururwa (nk'ibigori, imyumbati, n'ibindi), ibyo bikaba bihuye n'igitekerezo kiriho cyo kurengera ibidukikije n'iterambere rirambye.

Unilong ni utanga imiti kabuhariwe mu gukora (R) -Lactate URUBANZA10326-41-7. Birakomeye cyane kugenzura ubuziranenge. Hamwe nikoranabuhanga rigezweho ryumusaruro hamwe nitsinda ryabahanga R&D, (R) -IbikorwaURUBANZA10326-41-7 yakozwe irashobora kuzuza ibisabwa mumirima myinshi itandukanye kugirango ibicuruzwa bisukure kandi bihamye. Niba ubikeneye, nyamunekatwandikire.
