(R)-Lactate, helu CAS 10326-41-7. Loaʻa iā ia kekahi mau inoa inoa maʻamau, e like me (R) -2-hydroxypropionic acid, D-2-hydroxypropionic acid, etc. ʻO ka molecular formula o D-lactic acid he C₃H₆O₃, a ʻo ke kaumaha molekala ma kahi o 90.08. Hōʻike ʻia kona ʻano molekala e ka ʻoiaʻiʻo ʻo ka lactic acid ka liʻiliʻi liʻiliʻi liʻiliʻi o ke ʻano. ʻO ka ʻātoma kalapona ma ke kūlana α o ka pūʻulu carboxyl i loko o ka mole he ʻātoma kalapona asymmetric me ʻelua mau hoʻonohonoho, L (+) a me D (-), a ʻo ka D-lactic acid ma ʻaneʻi ma ka lima ʻākau. (R)-Lactate nā waiwai kemika maʻamau o nā waikawa monocarboxylic. ʻAkaʻawaʻawaʻa kona ʻano wai. Ke piʻi aku ka manaʻo ma mua o 50%, e hana ʻia ka lactic anhydride, e hana me kekahi mau mea waiʻona e hana i ka resin alkyd, a hiki ke hana i ka esterification intermolecular ma lalo o nā kūlana hoʻomehana e hana i ka lactyl lactic acid (C₆H₁₀O₅). Hiki ke hydrolyzed i ka D-lactic acid ma hope o ka dilution a me ka hoʻomehana. Eia kekahi, ma lalo o ka hana a ka zinc oxide dehydrating agent, ʻelua mau mole o (R) -Lactate e hoʻoneʻe i ʻelua mole o ka wai a me ka polymerize ponoʻī e hana i kahi dimer cyclic D-lactide (C₆H₈O₄, DLA), hiki ke hana i ka polymerized (R) -Lactate ma hope o ka lawa ʻana o ka wai. No ka mea ʻoi aku ka nui o ka waika lactic, ʻoi aku ka ikaika o kona makemake i ka esterification ponoʻī, ʻo ka lactic acid ka mea maʻamau ka hui ʻana o ka lactic acid a me ka lactide.

(R)-Lactate ʻike ʻia ma ke ʻano he wai ʻeleʻele ʻole a melemele liʻiliʻi liʻiliʻi ma ka lumi wela a me ke kaomi. He ʻala ʻawaʻawa a he hygroscopic. E hōʻike ana kāna hoʻoheheʻe wai i kahi hopena ʻakika. Hiki ke hoʻoheheʻe maikaʻi ʻia a hiki ke hoʻohui ʻia me ka wai, ethanol a i ʻole etera ma ka makemake, akā ʻaʻole hiki ke hoʻoheheʻe ʻia i ka chloroform. Ma nā ʻōlelo o nā ʻāpana kino, ʻo kona mānoanoa (20/20 ℃) ma waena o 1.20 ~ 1.22g / ml, ʻo kona helu hoʻoheheʻe he 52.8 ° C, ʻo 227.6 ° C kona wahi hoʻolapalapa, 3.8Pa kona kaomi mahu ma 25 ℃, ʻo kona helu uila he 109.9 ± 16.3 ° C, ʻo ia ka refractive index. ma kahi o 90.08, a he H₂O kona solubility i ka wai: 0.1 g/mL.

(R)-LactateCAS10326-41-7 kūpono no ka mālama ʻana ma kahi maloʻo a maloʻo, a pono e mālama ʻia mai ka mālamalama. ʻAʻole kūpono ia no ka mālama ʻana i waho. I ka manawa like, pono e mālama ʻia mai nā mea alkaline ikaika a me nā oxidants ikaika e hōʻoia i kona kūpaʻa a hiki ke mālama maikaʻi ʻia a hoʻohana ʻia.

Hoʻohana nui i ka D-lactic acid

Kahua lapaʻau

(R)-Lactate CAS10326-41-7 loaʻa i ka waiwai hoʻohana koʻikoʻi ma ke kahua lapaʻau. He kumu waiwai nui a waena paha ia no ka hoʻohui ʻana i nā lāʻau lapaʻau he nui. Ma keʻano he kikowaena chiral, (R)-Lactate CASʻO 10326-41-7 me ka hoʻomaʻemaʻe optical kiʻekiʻe (ʻoi aku ma mua o 97%) ka mea mua o nā mea chiral he nui a he hana koʻikoʻi i ka ʻoihana lāʻau. No ka laʻana, hiki ke hoʻohana ʻia e hana i nā lāʻau antihypertensive calcium antagonist, kahi hopena maikaʻi i ka hoʻomalu ʻana i ka hypertension. Ma ka hana ʻana i ka ʻōnaehana cardiovascular, kōkua ia i ka hoʻoponopono ʻana i nā pae koko a hāʻawi i ke kākoʻo ikaika no ka mālama ʻana i nā maʻi hypertensive.

ʻOihana kemika

(R)-LactateCASHe kuleana koʻikoʻi ka 10326-41-7 i ka ʻoihana kemika. ʻO nā esters ʻakika lactic i hana ʻia me (R)-LactateCAS10326-41-7 e like me ka mea maka i hoʻohana nui ʻia i ke kaʻina hana o nā huahana kemika he nui e like me nā mea ʻala, nā synthetic resin coatings, adhesives a me nā inika paʻi.

Nā mea hiki ke hoʻopau ʻia

D-lactic acidhe mea koʻikoʻi no ka bioplastic polylactic acid (PLA), he mea koʻikoʻi koʻikoʻi no ka hoʻomohala ʻana i nā mea hiki ke hoʻopau ʻia. ʻO ka polylactic acid, ma ke ʻano he ʻano hou o ka bio-based a me ka mea hiki ke hoʻololi hou ʻia, ua hana ʻia mai ka starch maka waiwai i unuhi ʻia mai nā kumuwaiwai mea kanu hou (e like me ke kulina, cassava, a me nā mea ʻē aʻe), e like me ka manaʻo o kēia manawa no ka mālama ʻana i ke kaiapuni a me ka hoʻomohala hoʻomau.

Unilong he mea hoʻolako kemika kūikawā i ka hana ʻana o (R)-Lactate CAS10326-41-7. He koʻikoʻi ma ka hoʻomalu maikaʻi. Me ka ʻenehana hana kiʻekiʻe a me kahi hui R&D ʻoihana, ka (R)-LactateCAS10326-41-7 hiki ke hoʻokō i nā koi o nā māla like ʻole no ka maʻemaʻe a me ka paʻa o ka huahana. Inā makemake ʻoe, e ʻoluʻolukāhea iā mā˚ou.
