iindaba

(R)-Lactate, inombolo ye-CAS yi-10326-41-7. Kwakhona kunezinye ii-aliases eziqhelekileyo, ezifana (R) -2-hydroxypropionic acid, i-D-2-hydroxypropionic acid, njl. I-molecular formula ye-D-lactic acid yi-C₃H₆O₃, kwaye ubunzima be-molecular malunga ne-90.08. Ubume bayo be-molecular bubonakaliswa yinyaniso yokuba i-lactic acid yi-molecule encinci ye-chiral kwindalo. I-athomu yekhabhoni kwindawo ye-α yeqela le-carboxyl kwimolekyuli yi-athomu ye-carbon asymmetric eneendlela ezimbini, i-L (+) kunye ne-D (-), kunye ne-D-lactic acid apha ilungile. (R) -I-Lactate ineempawu zeekhemikhali eziqhelekileyo ze-monocarboxylic acids. Isinyibiliko sayo esinamanzi sinobuthathaka obuneasidi. Xa ugxininiso lufikelela ngaphezu kwe-50%, luya kwenza i-lactic anhydride, iphendule kunye nezinye izinto zotywala ukuze zenze i-alkyd resin, kwaye inokungena kwi-intermolecular esterification phantsi kweemeko zokufudumeza ukwenza i-lactyl lactic acid (C₆H₁₀O₅). Inokuthi ifakwe i-hydrolyzed kwi-D-lactic acid emva kokuhlanjululwa kunye nokufudumeza. Ukongezelela, phantsi kwesenzo se-agent ye-dehydrating zinc oxide, iimolekyuli ezimbini ze (R) -Lactate zisusa iimolekyuli ezimbini zamanzi kunye ne-self-polymerize ukuze zenze i-cyclic dimer D-lactide (C₆H₈O₄, DLA), enokwenza i-polymerized (R) -Lactate emva kokuchithwa okwaneleyo. Ekubeni i-asidi ye-lactic igxininise ngakumbi, inamandla ngakumbi ukuthambekela kwayo kwi-self-esterification, i-lactic acid idla ngokuba ngumxube we-lactic acid kunye ne-lactide.

(R)-Lactate ibonakala njengolwelo olungenambala ukuya kumthubi kancinane olucacileyo kubushushu begumbi kunye noxinzelelo. Inuka muncu kancinci kwaye i-hygroscopic. Isisombululo sayo samanzi siya kubonisa ukusabela kwe-acidic. Inonyibiliko oluhle kwaye inokuxutywa namanzi, i-ethanol okanye i-ether ngokuthanda, kodwa ayinyibiliki kwi-chloroform. Ngokubhekiselele kwiparameters ezibonakalayo, ubuninzi bayo (20/20℃) buphakathi kwe-1.20 ~ 1.22g/ml, indawo yayo yokunyibilika yi-52.8 ° C, indawo yokubilisa yi-227.6 ° C, uxinzelelo lomphunga yi-3.8Pa kwi-25 ℃, i-flash point yi-16.3 C esebenzayo malunga ne-16.3 ° C, i-16. 1.451, kwaye ubunzima bayo be-molecular malunga ne-90.08, kwaye ukunyibilika kwayo emanzini ngu-H₂O: 0.1 g / mL.

(R)-LactateCAS10326-41-7 ifanele ukugcinwa kwindawo epholileyo neyomileyo, kwaye kufuneka igcinwe kude nokukhanya. Ayifanelekanga ukugcinwa kwangaphandle. Kwangaxeshanye, kufuneka igcinwe kude nezinto ezomeleleyo zealkaline kunye neoxidants ezomeleleyo ukuqinisekisa ukuzinza kwayo kunye nokwenza ukuba igcinwe ngcono kwaye isetyenziswe.

Ukusetyenziswa okubalulekileyo kwe-D-lactic acid

Intsimi yezonyango

(R)-Lactate CAS10326-41-7 inexabiso elibalulekileyo lesicelo kwintsimi yezonyango. Yimathiriyeli ekrwada engundoqo okanye ephakathi kwi-synthesis yamachiza amaninzi. Njengeziko lokutshiza, (R) -Lactate CASI-10326-41-7 kunye nococeko oluphezulu lwe-optical (ngaphezulu kwe-97%) yi-precursor yezinto ezininzi ze-chiral kwaye idlala indima ebaluleke kakhulu kwishishini lamachiza. Ngokomzekelo, ingasetyenziselwa ukuvelisa iziyobisi ze-calcium antagonist antihypertensive, ezinempembelelo entle ekulawuleni uxinzelelo lwegazi. Ngokusebenza kwinkqubo ye-cardiovascular system, inceda ukulawula amanqanaba oxinzelelo lwegazi kunye nokubonelela ngenkxaso eqinile kunyango lwezigulane eziphezulu.

Ishishini lemichiza

(R)-LactateCASI-10326-41-7 idlala indima ebaluleke kakhulu kwishishini lemichiza. I-Lactic acid esters eveliswa nge-(R)-LactateCASI-10326-41-7 njengezinto eziluhlaza zisetyenziswa ngokubanzi kwinkqubo yokuvelisa iimveliso ezininzi zeekhemikhali ezifana neziqhumiso, iingubo zokwenziwa kwe-resin, i-adhesives kunye neenki zokushicilela.

Izinto ezinokonakala

D-lactic acidyimathiriyeli ekrwada ebalulekileyo ye-bioplastic polylactic acid (PLA), enokubaluleka okude kakhulu ekuphuhliseni izinto ezinokonakala. I-Polylactic acid, njengohlobo olutsha lwezinto eziphilayo ezisekelwe kwi-bio-based kunye ne-renewable biodegradable material, zenziwe kwi-starch ekrwada ekhutshwe kwimithombo yezityalo ezihlaziyiweyo (ezifana nombona, i-cassava, njl.), ehambelana nombono wangoku wokukhuselwa kwendalo kunye nophuhliso oluzinzileyo.
