nkhani

(R) - Lactate, Nambala ya CAS ndi 10326-41-7. Imakhalanso ndi zina zodziwika bwino, monga (R) -2-hydroxypropionic acid, D-2-hydroxypropionic acid, etc. Maselo a D-lactic acid ndi C₃H₆O₃, ndipo kulemera kwa maselo ndi pafupifupi 90.08. Mapangidwe ake a mamolekyulu amadziwika kuti lactic acid ndiye molekyulu yaying'ono kwambiri m'chilengedwe. Atomu ya kaboni pamalo a α a gulu la carboxyl mu molekyulu ndi atomu ya carbon asymmetric yokhala ndi masinthidwe awiri, L (+) ndi D (-), ndipo D-lactic acid pano ndi dzanja lamanja. (R) -Lactate imakhala ndi mankhwala enaake a monocarboxylic acid. Njira yake yamadzimadzi imakhala yofooka acidic. Pamene ndende ifika kupitirira 50%, imapanga pang'ono lactic anhydride, imachita ndi zinthu zina za mowa kuti ipange alkyd resin, ndipo imatha kuchitidwa ndi intermolecular esterification pansi pa kutentha kuti ipange lactyl lactic acid (C₆H₁₀O₅). Itha kupangidwa ndi hydrolyzed kukhala D-lactic acid pambuyo pa dilution ndi kutentha. Komanso, pansi pa zochita za dehydrating agent zinc oxide, mamolekyu awiri a (R) -Lactate amachotsa mamolekyu awiri a madzi ndi kudzipangira polima kuti apange cyclic dimer D-lactide (C₆H₈O₄, DLA), yomwe imatha kupanga polymerized (R) -Lactate pambuyo pa kuchepa kwa madzi okwanira. Popeza kuchuluka kwa lactic acid kumapangitsa kuti chizoloŵezi chake chodzidzimutsa chikhale cholimba, lactic acid nthawi zambiri imakhala yosakaniza lactic acid ndi lactide.

(R)- Lactate amawoneka ngati madzi a viscous opanda mtundu mpaka achikasu pang'ono pa kutentha ndi kupanikizika. Kumanunkhiza wowawa pang'ono ndipo ndi hygroscopic. Njira yake yamadzimadzi imawonetsa acidic reaction. Ili ndi kusungunuka kwabwino ndipo imatha kusakanizidwa ndi madzi, ethanol kapena ether mwakufuna kwake, koma imakhala yosasungunuka mu chloroform. Kumbali ya magawo a thupi, kachulukidwe ake (20/20 ℃) ​​ndi pakati pa 1.20 ~ 1.22g/ml, malo ake osungunuka ndi 52.8 ° C, kuwira kwake ndi 227.6 ° C, mphamvu yake ya nthunzi ndi 3.8Pa pa 25 ℃, mfundo yake yowunikira ndi 1639. 1.451, ndipo kulemera kwake kwa maselo ndi pafupifupi 90.08, ndipo kusungunuka kwake m'madzi ndi H₂O: 0.1 g/mL.

(R) - LactateCAS10326-41-7 ndi yoyenera kusungidwa pamalo ozizira ndi owuma, ndipo iyenera kusungidwa kutali ndi kuwala. Sikoyenera kusungirako kunja. Panthawi imodzimodziyo, iyenera kusungidwa kutali ndi zinthu zamphamvu zamchere ndi zowonjezera zowonjezera zowonjezera kuti zitsimikizire kukhazikika kwake ndikupangitsa kuti zisungidwe bwino ndikugwiritsidwa ntchito.

Kugwiritsa ntchito kwambiri D-lactic acid

Malo azachipatala

(R) - Lactate CAS10326-41-7 ali ndi phindu lofunikira pazachipatala. Ndi zofunika zopangira kapena wapakatikati kwa synthesis ambiri mankhwala. Monga chiral center, (R) -Lactate CAS10326-41-7 yokhala ndi kuyera kwakukulu (kuposa 97%) ndiye kalambulabwalo wa zinthu zambiri za chiral ndipo imagwira ntchito yofunika kwambiri pamakampani opanga mankhwala. Mwachitsanzo, angagwiritsidwe ntchito kupanga calcium antagonist antihypertensive mankhwala, amene ali ndi zotsatira zabwino kulamulira matenda oopsa. Pogwiritsa ntchito dongosolo la mtima, zimathandiza kuchepetsa kuthamanga kwa magazi ndikupereka chithandizo champhamvu cha chithandizo cha odwala matenda oopsa.

Makampani opanga mankhwala

(R) - LactateCAS10326-41-7 imagwira ntchito yofunika kwambiri pamakampani opanga mankhwala. Lactic acid esters opangidwa ndi (R) -LactateCAS10326-41-7 monga zopangira zimagwiritsidwa ntchito kwambiri popanga zinthu zambiri zama mankhwala monga zonunkhira, zokutira zopangira utomoni, zomatira ndi inki zosindikizira.

Zida zowonongeka

D-lactic asidindi chinthu chofunikira kwambiri cha bioplastic polylactic acid (PLA), chomwe chili ndi tanthauzo lalikulu pakupanga zinthu zowonongeka. Asidi wa Polylactic, monga mtundu watsopano wa zinthu zomwe zimatha kuwonongeka ndi zachilengedwe, zimapangidwa kuchokera ku zopangira zowuma zomwe zimatengedwa kuchokera kuzinthu zongowonjezwdwa za zomera (monga chimanga, chinangwa, ndi zina zotero), zomwe zikugwirizana ndi lingaliro lamakono la kuteteza chilengedwe ndi chitukuko chokhazikika.

Unilong ndi ogulitsa mankhwala okhazikika pakupanga (R) -Lactate CAS10326-41-7. Ndi okhwima mu ulamuliro khalidwe. Ndiukadaulo wapamwamba wopanga komanso gulu la akatswiri a R&D, (R) -LactateCAS10326-41-7 yopangidwa imatha kukwaniritsa zofunikira zamagulu osiyanasiyana azinthu zoyera komanso zokhazikika. Ngati mukuifuna, chondeLumikizanani nafe.
