xov xwm

(R)-LactateCAS Nr .: 10326-41-7. Nws kuj muaj qee cov npe npe, xws li (R)-2-hydroxypropionic acid, D-2-hydroxypropionic acid, thiab lwm yam. Cov mis molecular ntawm D-lactic acid yog C₃H₆O₃, thiab qhov hnyav molecular yog txog 90.08. Nws cov qauv molecular yog tus cwj pwm los ntawm qhov tseeb tias lactic acid yog qhov tsawg tshaj plaws chiral molecule hauv xwm. Cov pa roj carbon atom ntawm α txoj hauj lwm ntawm pawg carboxyl nyob rau hauv lub molecule yog asymmetric carbon atom nrog ob configurations, L (+) thiab D (-), thiab D-lactic acid ntawm no yog sab xis. (R)-Lactate muaj cov tshuaj lom neeg ntawm monocarboxylic acids. Nws cov tshuaj aqueous yog weakly acidic. Thaum cov concentration nce mus txog ntau tshaj 50%, nws yuav ua ib feem ntawm lactic anhydride, hnov ​​​​mob nrog qee yam cawv los ua alkyd resin, thiab tuaj yeem ua rau muaj kev cuam tshuam ntawm cov esterification nyob rau hauv cov cua kub kom tsim lactyl lactic acid (C₆H₁₀O₅). Nws tuaj yeem hydrolyzed rau hauv D-lactic acid tom qab dilution thiab cua sov. Tsis tas li ntawd, nyob rau hauv qhov kev txiav txim ntawm lub dehydrating tus neeg sawv cev zinc oxide, ob lub molecules ntawm (R)-Lactate tshem tawm ob lub molecules ntawm dej thiab nws tus kheej-polymerize los ua ib tug cyclic dimer D-lactide (C₆H₈O₄, DLA), uas tuaj yeem tsim polymerized (R)-Lactate tom qab lub cev qhuav dej txaus. Txij li thaum lub concentration ntawm lactic acid ntau dua, qhov muaj zog nws nyiam nws tus kheej-esterification, lactic acid feem ntau yog sib xyaw ntawm lactic acid thiab lactic.

(R)-Lactate tshwm raws li cov xim tsis muaj xim rau me ntsis daj ntshiab viscous kua ntawm chav tsev kub thiab siab. Nws tsw qab me ntsis qaub thiab yog hygroscopic. Nws cov tshuaj aqueous yuav qhia cov tshuaj tiv thaiv acidic. Nws muaj cov solubility zoo thiab tuaj yeem tov nrog dej, ethanol lossis ether ntawm qhov siab, tab sis nws yog insoluble hauv chloroform. Nyob rau hauv cov nqe lus ntawm lub cev tsis, nws qhov ceev (20/20 ℃) ​​yog nyob nruab nrab ntawm 1.20 ~ 1.22g / ml, nws melting point yog 52.8 ° C, nws boiling point yog 227.6 ° C, nws vapor siab yog 3.8Pa ntawm 25 ℃, nws qhov taw tes taw tes yog 109.9 ± 16.1 ° C, nws reactive thiab 16.1 ° C. molecular hnyav yog hais txog 90.08, thiab nws solubility hauv dej yog H₂O: 0.1 g / mL.

(R)-LactateCAS10326-41-7 yog tsim rau cia nyob rau hauv ib qho chaw txias thiab qhuav, thiab yuav tsum tau ceev kom deb ntawm lub teeb. Nws tsis haum rau kev cia sab nraum zoov. Nyob rau tib lub sijhawm, nws yuav tsum tau khaws cia kom deb ntawm cov khoom muaj zog alkaline thiab muaj zog oxidants kom nws ruaj khov thiab ua kom nws zoo dua khaws cia thiab siv.

Kev siv tseem ceeb ntawm D-lactic acid

Kev kho mob teb

(R)-Lactate CAS10326-41-7 muaj qhov tseem ceeb ntawm daim ntawv thov kev kho mob. Nws yog ib qho tseem ceeb raw khoom los yog nruab nrab rau synthesis ntawm ntau yam tshuaj. Raws li lub chaw chiral, (R)-Lactate CAS10326-41-7 nrog lub siab kho qhov muag purity (ntau dua 97%) yog tus thawj coj ntawm ntau cov tshuaj chiral thiab ua lub luag haujlwm tseem ceeb hauv kev lag luam kws tshuaj. Piv txwv li, nws tuaj yeem siv los tsim cov tshuaj calcium antagonist antihypertensive, uas muaj txiaj ntsig zoo rau kev tswj ntshav siab. Los ntawm kev ua haujlwm ntawm cov hlab plawv, nws pab tswj cov ntshav siab thiab muab kev txhawb zog rau kev kho cov neeg mob ntshav siab.

Kev lag luam tshuaj

(R)-LactateCAS10326-41-7 plays lub luag haujlwm tseem ceeb hauv kev lag luam tshuaj. Lactic acid esters tsim nrog (R)-LactateCAS10326-41-7 raws li cov khoom siv raw tau siv dav hauv cov txheej txheem tsim khoom ntawm ntau cov khoom siv tshuaj xws li tshuaj tsw qab, hluavtaws cob txheej, nplaum thiab luam ntawv inks.

Cov ntaub ntawv degradable

D-lactic acidyog ib qho tseem ceeb raw khoom rau bioplastic polylactic acid (PLA), uas muaj qhov tseem ceeb heev rau kev tsim cov khoom degradable. Polylactic acid, raws li ib yam tshiab ntawm bio-based thiab txuas ntxiv biodegradable cov ntaub ntawv, yog tsim los ntawm cov hmoov txhuv nplej siab raw cov ntaub ntawv muab rho tawm los ntawm cov nroj tsuag txuas ntxiv (xws li pob kws, cassava, thiab lwm yam), uas yog raws li lub tswv yim tam sim no ntawm kev tiv thaiv ib puag ncig thiab kev txhim kho kom ruaj khov.

Unilong yog ib lub chaw muag tshuaj tshwj xeeb hauv kev tsim khoom ntawm (R)-Lactate CAS10326-41-7. Nws yog qhov nruj heev hauv kev tswj kom zoo. Nrog cov cuab yeej tsim khoom siab heev thiab pab pawg R & D kev tshaj lij, (R)-LactateCAS10326-41-7 ua tau raws li qhov yuav tsum tau muaj ntawm ntau yam sib txawv rau cov khoom purity thiab stability.
