Title (EN) PROCESS OF PRODUCING PALM-BASED POLYOL ESTERS
(FR) PROCÉDÉ DE PRODUCTION D'ESTERS DE POLYOL À BASE D'HUILE DE PALME
Abstract:
(EN) The present invention relates to a process of producing palm-based polyol esters (POE) through a solventless and autocatalytic reaction. The process comprising steps of esterifying (104) palm-based fatty acid and pentaerythritol under controlled condition followed by purifying (108) esterification reaction mixture using short path distillation method to remove unreacted acid. In particular, esterification reaction is conducted under vacuum pressure of at least 40 000 Pa (400 mbar), at a temperature in the range of at least 140 to 200 °C for a period between 2 to 6 hours. The purification of esterification mixture by using short path distillation is conducted attemperature ranging from at least 200 to 225 °C and reduced pressure of at least 5 Pa (0.05 mbar) to remove unreacted acid.
(FR) La présente invention concerne un procédé de production d'esters de polyol (POE) à base d'huile de palme par une réaction sans solvant et autocatalytique. Le procédé comprend des étapes d'estérification (104) d'acide gras à base d'huile de palme et de pentaérythritol dans des conditions contrôlées suivies d'une purification (108) du mélange réactionnel d'estérification à l'aide d'un procédé de distillation à court trajet pour éliminer l'acide n'ayant pas réagi. En particulier, la réaction d'estérification est effectuée sous une pression sous vide d'au moins 40 000 Pa (400 mbar), à une température dans la plage d'au moins 140 à 200 °C pendant une durée comprise entre 2 et 6 heures. La purification du mélange d'estérification à l'aide d'une distillation à court trajet est effectuée à une température dans une plage d'au moins 200 à 225 °C et à une pression réduite d'au moins 5 Pa (0,05 mbar) pour éliminer l'acide n'ayant pas réagi.
