izindaba

(R)-Lactate, inombolo ye-CAS ithi 10326-41-7. Futhi inezinye iziteketiso ezivamile, ezifana (R) -2-hydroxypropionic acid, D-2-hydroxypropionic acid, njll. Ifomula ye-molecular ye-D-lactic acid i-C₃H₆O₃, futhi isisindo se-molecular cishe singama-90.08. Ukwakheka kwayo kwamangqamuzana kubonakala yiqiniso lokuthi i-lactic acid iyi-molecule ye-chiral encane kunazo zonke emvelweni. I-athomu ye-carbon endaweni engu-α yeqembu le-carboxyl ku-molecule iyi-athomu ye-asymmetric carbon enokucushwa okubili, u-L (+) no-D (-), kanti i-D-lactic acid lapha isesandleni sokudla. (R) -I-Lactate inezakhi zamakhemikhali ezijwayelekile ze-monocarboxylic acid. Isixazululo saso esinamanzi sine-asidi ebuthakathaka. Lapho ukugxilisa ingqondo kufinyelela ngaphezu kuka-50%, izokwakha ingxenye ye-lactic anhydride, isabelane nezinye izinto zotshwala ukuze yakhe i-alkyd resin, futhi ingangena esterification ye-intermolecular ngaphansi kwezimo zokushisa ukuze yakhe i-lactyl lactic acid (C₆H₁₀O₅). Ingenziwa i-hydrolyzed ibe yi-D-lactic acid ngemva kokuhlanjululwa nokushisa. Ngaphezu kwalokho, ngaphansi kwesenzo se-zinc oxide ye-agent eqeda amanzi emzimbeni, ama-molecule amabili e-(R) -Lactate asusa ama-molecule amabili amanzi futhi azenzele i-polymerize ukuze enze i-cyclic dimer D-lactide (C₆H₈O₄, DLA), engakha i-polymerized (R) -Lactate ngemva kokuphelelwa amandla okwanele. Njengoba i-lactic acid igxila kakhulu, kuqina ukuthambekela kwayo kokuzikhukhumeza, i-lactic acid ngokuvamile iyingxube ye-lactic acid ne-lactide.

(R)-Lactate ibonakala njengoketshezi lwe-viscous olungenambala ukuya kokuphuzi olucacile ekamelweni lokushisa nokucindezela. Inuka kancane futhi i-hygroscopic. Isixazululo saso esinamanzi sizobonisa ukusabela kwe-acidic. Inoncibilika kahle futhi ingaxutshwa namanzi, i-ethanol noma i-ether ngokuthanda kwayo, kodwa ayincibiliki ku-chloroform. Ngokuya ngemingcele yomzimba, ukuminyana kwayo (20/20℃) kuphakathi kuka-1.20 ~ 1.22g/ml, indawo yokuncibilika kwayo ingu-52.8°C, indawo yokubilisa ingu-227.6°C, umfutho wayo womhwamuko ngu-3.8Pa ku-25℃, iphoyinti layo le-Flash point liyi-16.3C ± 169. 1.451, futhi isisindo sayo samangqamuzana silinganiselwa ku-90.08, futhi ukunyibilika kwayo emanzini kungu-H₂O: 0.1 g/mL.

(R)-LactateI-CAS10326-41-7 ifanele ukugcinwa endaweni epholile neyomile, futhi kufanele igcinwe kude nokukhanya. Ayifanele isitoreji sangaphandle. Ngesikhathi esifanayo, idinga ukugcinwa kude nezinto eziqinile ze-alkaline kanye nama-oxidants aqinile ukuze kuqinisekiswe ukuzinza kwayo futhi kuyenze igcinwe kangcono futhi isetshenziswe.

Ukusetshenziswa okubalulekile kwe-D-lactic acid

Inkambu yezokwelapha

(R)-Lactate I-CAS10326-41-7 inenani elibalulekile lesicelo emkhakheni wezokwelapha. Iwukhiye wezinto ezingavuthiwe noma ezimaphakathi zokwenziwa kwezidakamizwa eziningi. Njengesikhungo se-chiral, (R) -Lactate I-CASI-10326-41-7 ene-optical purity ephezulu (ngaphezu kwama-97%) iyisandulela sezinto eziningi ze-chiral futhi idlala indima ebalulekile embonini yezemithi. Isibonelo, ingasetshenziswa ukukhiqiza izidakamizwa ze-calcium antagonist antihypertensive, ezinomphumela omuhle ekulawuleni umfutho wegazi ophezulu. Ngokusebenza ohlelweni lwenhliziyo, kusiza ukulawula amazinga omfutho wegazi futhi inikeza ukwesekwa okuqinile kokwelashwa kweziguli ezinomfutho wegazi ophakeme.

Imboni yamakhemikhali

(R)-LactateI-CASI-10326-41-7 idlala indima ebaluleke kakhulu embonini yamakhemikhali. I-Lactic acid esters ekhiqizwa nge-(R)-LactateI-CASI-10326-41-7 njengempahla eluhlaza isetshenziswa kabanzi ekukhiqizeni imikhiqizo eminingi yamakhemikhali njengeziqholo, okokwenziwa kwe-resin coating, okunamathelayo noyinki wokuphrinta.

Izinto eziwohlokayo

I-D-lactic acidiyimpahla ebalulekile ye-bioplastic polylactic acid (PLA), enokubaluleka okufinyelele kude ekuthuthukisweni kwezinto ezibolayo. I-Polylactic acid, njengohlobo olusha lwe-bio-based and renewable biodegradable material, yenziwa ngezinto ezingavuthiwe zesitashi ezikhishwe ezinsizeni zezitshalo ezivuselelekayo (njengommbila, umdumbula, njll.), okuhambisana nomqondo wamanje wokuvikelwa kwemvelo kanye nentuthuko esimeme.

I-unilong ungumhlinzeki wamakhemikhali osebenza ngokukhethekile ekukhiqizeni i-(R)-Lactate I-CAS10326-41-7. Iqinile ekulawuleni ikhwalithi. Ngobuchwepheshe obuphambili bokukhiqiza kanye nethimba le-R&D eliqeqeshiwe, i-(R)-LactateI-CASI-10326-41-7 ekhiqizwayo ingahlangabezana nezidingo zezinkambu eziningi ezihlukene zokuhlanzeka nokuqina komkhiqizo. Ngicela, uma uyidingaXhumana nathi.
