Title
(EN) PROCESS FOR THE RECOVERY OF POLYHYDROXYALKANOIC ACID
(FR) PROCEDE DE RECUPERATION D'UN ACIDE HYDROXYALCANOIQUE
Abstract
(EN)
A hydroxyalkanoic acid (PHA) is recovered from matter derived from living organisms by dissolving the PHA in a solvent which is a lower ketone, dialkyl ether or a lower alcohol or a monocarboxylic acid ester thereof, separating the solution from such matter and recovering PHA from the solution.
(FR)
L'invention concerne un procédé de récupération d'un acide hydroxyalcanoïque (PHA) à partir de matière obtenue d'organismes vivants, par dissolution du PHA dans un solvant pouvant être un cétone de faible poids moléculaire, un éther de dialcoyle, un alcool de faible poids moléculaire ou bien encore un ester d'acide monocarboxylique de celui-ci. La solution obtenue est séparée de la matière susmentionnée et le PHA est extrait de cette solution.
