Résumé

Procédé de production d'esters cycliques dimériques au départ d'un brut d'estérification obtenu soit par mélange d'un acide lactique et/ou glycolique avec un de ses esters soit par extraction à un moment bien déterminé de l'étape d'estérification. Ce procédé comprend une dimérisation douce et sélective de l'ester, suivie d'une cyclisation douce et sélective de l'ester dimérisé et enfin la purification du brut obtenu.
