Rau kev thov ntawmDL-Lactide
DL-Lactideyog siv los tsim 2-hydroxy-propionic acid 1-(1-phenyl-ethoxycarbonyl)-ethyl ester. Nws ua raws li ib qho tseem ceeb raw khoom thiab ib tug nruab nrab siv nyob rau hauv organic synthesis, kws, agrochemicals thiab dyes. Nws muaj kev koom tes hauv enzymatic alcoholysis los tsim cov alkyl (R)-lactates thiab alkyl (S, S)-lactyllactates.
DL-Lactidefeem ntau yog siv los ua cov txheej txheem tiv thaiv hauv lub qhov txhab, lossis ua cov thauj tog rau nkoj, screws lossis mesh hauv kev phais, vim nws degrades nyob rau hauv li ntawm rau lub hlis mus rau innocuous lactic acid.
