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.
