(R) -Lactate, CAS nhamba ndeye 10326-41-7. Iyo inewo mamwe mazita akajairika, akadai (R) -2-hydroxypropionic acid, D-2-hydroxypropionic acid, etc. The molecular formula yeD-lactic acid ndeye C₃H₆O₃, uye molecular weight inenge 90.08. Chimiro chayo chemolecular chinoratidzwa nenyaya yekuti lactic acid ndiyo diki chiral molecule mune zvakasikwa. Kabhoni atomu panzvimbo α yeboka recarboxyl mumorekuru iasymmetric kabhoni atomu ine magadzirirwo maviri, L (+) uye D (-), uye iyo D-lactic acid pano iri kurudyi-ruoko. (R) -Lactate ine maitiro emakemikari emonocarboxylic acids. Mushonga wayo une aqueous hauna kusimba acidic. Kana iyo yekusungwa inosvika kupfuura makumi mashanu muzana, inozoita chikamu lactic anhydride, inobata pamwe nezvimwe zvinwiwa zvedoro kuti igadzire alkyd resin, uye inogona kupinda mukati meiyo esterification pasi pekupisa mamiriro ekugadzira lactyl lactic acid (C₆H₁₀O₅). Inogona kuve hydrolyzed muD-lactic asidhi mushure mekunyorovesa uye kupisa. Mukuwedzera, pasi pekuita kweiyo dehydrating agent zinc oxide, mamorekuru maviri e (R) -Lactate anobvisa mamorekuru maviri emvura uye self-polymerize kuti aite cyclic dimer D-lactide (C₆H₈O₄, DLA), iyo inogona kugadzira polymerized (R) -Lactate mushure mekushaya mvura yakakwana. Sezvo iyo yakanyanya kuomesesa iyo lactic asidhi, iyo yakasimba maitiro ayo ekuzvi-esterification, lactic acid inowanzove musanganiswa welactic acid uye lactide.
(R)-Lactate inoita senge isina ruvara kusvika kune yero zvishoma yakajeka viscous fluid pakamuri tembiricha uye kumanikidza. Inonhuwa kuvava zvishoma uye ine hygroscopic. Mhinduro yayo ine aqueous icharatidza acidic reaction. Iine solubility yakanaka uye inogona kusanganiswa nemvura, ethanol kana ether pakuda, asi haigoneki muchloroform. Panyaya yezvimiro zvemuviri, density yayo (20/20 ℃) iri pakati pe1.20 ~ 1.22g/ml, kunyunguduka kwayo i52.8°C, kuvira kwayo i227.6°C, mhute yayo i3.8Pa pa25℃, inopenya i1693°C ± 169.9 1.451, uye huremu hwayo hunoita 90.08, uye kunyungudika kwayo mumvura iH₂O: 0.1 g/mL.
(R) -LactateCAS10326-41-7 inokodzera kuchengetwa munzvimbo inotonhorera uye yakaoma, uye inofanira kuchengetedzwa kure nechiedza. Haikodzeri kuchengetedza kunze. Panguva imwecheteyo, inoda kuchengetwa kubva kune yakasimba alkaline zvinhu uye yakasimba oxidants kuti ive nechokwadi chekugadzikana kwayo uye kuita kuti ichengetedzwe zviri nani uye kushandiswa.
Kushandiswa kwakakosha kweD-lactic acid
Munda wezvokurapa
(R) -Lactate CAS10326-41-7 ine kukosha kwekushandisa kwakakosha munharaunda yekurapa. Icho chinhu chakakosha mbishi kana yepakati pakuumbwa kwemishonga yakawanda. Sechiral centre, (R) -Lactate CAS10326-41-7 ine yakakwira optical kuchena (kupfuura 97%) ndiyo inotungamira yeakawanda chiral zvinhu uye inoita basa rinokosha muindasitiri yemishonga. Semuenzaniso, inogona kushandiswa kugadzira calcium antagonist antihypertensive mishonga, ine simba rakanaka pakudzora hypertension. Nekuita pahurongwa hwemoyo, inobatsira kudzora huwandu hweropa uye inopa rutsigiro rwakasimba rwekurapa kwevarwere vane hypertension.
Indasitiri yemakemikari
(R) -LactateCAS10326-41-7 inobata basa rakakosha muindasitiri yemakemikari. Lactic acid esters inogadzirwa ne (R) -LactateCAS10326-41-7 seyakagadziriswa inoshandiswa zvakanyanya mukugadzirwa kwezvinhu zvakawanda zvemakemikari senge zvinonhuhwirira, zvekugadzira resin coatings, zvinonamira uye ingi dzekudhinda.
Degradable materials
D-lactic acidchinhu chakakosha mbishi yebioplastic polylactic acid (PLA), ine kukosha kukuru mukugadzirwa kwezvinhu zvinoparara. Polylactic acid, semhando itsva yebio-based uye inovandudzwa biodegradable material, inogadzirwa kubva kune starch yakasvibirira yakatorwa kubva kune zvinogadziriswazve zviwanikwa zvemiti (sechibage, cassava, nezvimwewo), iyo inoenderana nemafungiro ezvino ekuchengetedzwa kwezvakatipoteredza uye kusimudzira kwakasimba.
Unilong mutengesi wemakemikari anoshanda mukugadzira (R) -Lactate CAS10326-41-7. Inonyanya kuoma mukutonga kwehutano. Nehunyanzvi hwekugadzira tekinoroji uye nenyanzvi R&D timu, iyo (R) -LactateCAS10326-41-7 inogadzirwa inogona kusangana nezvinodiwa zveminda yakawanda yakasiyana yekuchena kwechigadzirwa uye kugadzikana. Kana muchiida ndapotataura nesu.
