    Abstract: 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.

    Abstract: The invention relates to the production of epoxidized methyl oleate from palm methyl oleate using in-situ epoxidation for preparation of plasticizers. Epoxidized palm-based methyl oleate (referred to as "EPMO") can be prepared by epoxidizing palm-based methyl oleate with an acid and peroxide. Epoxidation can be performed under controlled reaction conditions to provide EPMO having an iodine value in the range of 2 – 6 g I 2 /100 g. EPMO can be employed in plasticizer compositions, either alone or in combination with other plasticizers to substitute petroleum-based dioctyl phthalate (DOP) and the said EPMO is phthalate-free; which means that undesirable leakage of medical plastics has been mitigated.

    Abstract translation: 本发明涉及使用原位环氧化制备增塑剂而由棕榈酸甲酯制备环氧化油酸甲酯。 环氧化的基于棕榈的油酸甲酯(称为“EPMO”)可以通过用酸和过氧化物环氧化棕榈基油酸甲酯来制备。 环氧化可以在受控的反应条件下进行,以提供具有2-6g I 2 / 100g范围内的碘值的EPMO。 EPMO可用于增塑剂组合物中,单独使用或与其它增塑剂组合使用以代替石油基邻苯二甲酸二辛酯(DOP),且所述EPMO不含邻苯二甲酸酯; 这意味着医疗塑料的不合需要的泄漏已经被减轻。
