Abstract: front page image
(DE)Die vorliegende Erfindung betrifft drei Varianten zur Herstellung einer Mischung aus von Milchsäure abgeleiteten cyclischen Diestern und insbesondere eines Racemates von Dilactid. Dabei kann wahlweise von den entsprechenden α-Hydroxycarbonsäuren, den entsprechenden cyclischen Diestern oder Oligomeren der entsprechenden α-Hydroxycarbonsäuren ausgegangen werden.
(EN)The present invention relates to three variants for preparing a mixture of cyclic diesters derived from lactic acid and especially a racemate of dilactide. This can proceed, as desired, from the corresponding a-hydroxycarboxylic acids, the corresponding cyclic diesters or oligomers of the corresponding a-hydroxycarboxylic acids.
(FR)L'invention concerne trois variantes de préparation d'un mélange de diesters cycliques dérivés d'acide lactique et, en particulier, un racémate de dilactide. Ceci permet d'obtenir, de façon sélective, les acides α-hydrocycarboniques, les diesters cycliques correspondants ou les oligomères des acides α-hydrocarboniques correspondants.
