(r)-lactate me te cas 10326-41-7
Ko te waikawa D-lactic he matū. Ko te tātai rāpoi ko C3H6O3. Ko te waikawa D-lactic 90% he waikawa lactic whatu (chiral) teitei i hangaia e te hangarau FERMENTATION koiora ma te whakamahi i nga warowaiha rite ki te huka hei rauemi mata. Ko te hua kua oti o te waikawa D-lactic he wai kawa kore tae, he kowhai marama marama ranei me te reka paku kawa; he hygroscopic, a ka whakaatu te wairewa wai i te tauhohenga waikawa. Ka taea te whakauru noa ki te wai, ki te waihano, ki te etera ranei, karekau e rewa ki te chloroform.

Ka whakamahia te nuinga ki te tukatuka me te hanga i nga rauemi waikawa polylactic me te whakahiato o nga raau taero chiral me nga takawaenga pesticide.
Pūhui kirira
Ko nga hākawa waikawa lactic e whakamahi ana i te waikawa D-lactic hei rauemi mata e whakamahia nuitia ana i roto i te hanga hinu kakara, paninga kapia waihanga, whakapiri me te waituhi taa, me te horoi hoki i nga paipa hinu me nga umanga hiko. I roto ia ratou, ka taea te whakakotahi i te D-methyl lactate ki te wai me nga momo whakarewa polar, ka taea te whakakore i te nitrocellulose, te acetate cellulose, te cellulose acetobutyrate, me etahi atu me nga momo polymers synthetic polar, a he tohu whakarewa. He whakarewa pai me te ira koropuke teitei na ona painga o te teitei o te pāmahana me te tere whakaetonga puhoi. Ka taea te whakamahi hei waahanga o te whakarewa whakauru hei whakapai ake i te mahi me te whakarewatanga. I tua atu, ka taea hoki te whakamahi hei rauemi mata mo nga rongoa, pesticides me nga kaitapa mo te whakahiato o etahi atu puhui chiral. , Takawaenga.
rauemi whakaheke
Ko te waikawa lactic te rauemi mata mo te waikawa polylactic bioplastic (PLA). Ko nga ahuatanga tinana o nga rawa PLA e whakawhirinaki ana ki te hanganga me te ihirangi o D me L inemate. Ko te racemate D, te waikawa L-polylactic (PDLLA) i whakahiatohia mai i te racemic D, he hanganga amorphous te waikawa L-lactic, a he ngoikore ona taonga miihini, he poto te wa whakaheke, ka puta te whakaheke i roto i te tinana, me te tere o te whakaheke 50%. % neke atu ranei, he iti te tono. Ko nga wahanga mekameka o te waikawa L-polylactic (PLLA) me te waikawa D-polylactic (PDLA) he mea whakarite i nga wa katoa, a, ko to ratou tioata, te kaha miihini me te waahi whakarewa he teitei ake i era o te PDLLA.
