Epoxidized vegetable oils are the most surprise importance because of their sustainable,rnrenewable and environment friendly nature and they are substituted the petrochemical resourceâ€™s.rnThe main objective of this study was investigating the production of epoxidized oil fromrnPodocarpus falcatus seed through epoxidation reaction via sulphuric acid as homogeneousrnreaction with perfomic acid. The physicochemical characteristics of seed, oil and epoxidized oilrnof Podocarpus falcatus were investigated using standard analytical methods. The proximaterncompositions of the seeds were as follows: moisture (6.02%), ash (2.25%), crude fat (65.73%),rnseed density (1.04 g/mrn), volatile matter (86.46), and fixed carbon content (5.3%). In addition tornthis, physicochemical characteristics of Podocarpus falcatus oil were moisture content (2.2 %),rnviscosity (30.5 m.Pa. s) acid value (3.11 mg KOH/g, free fatty acid (1.54 mg KOH/g). rnsaponification value (181.93 mg KOH/g) specific gravity (0.922). iodine value (107.18 g I2/ g 100rnoil %). and refractive index (1.468). The experiments were carried out by Design-Expert 7.0.0rnthree-level-three-factor Box -Behnken Design and it was applied for experimental design andrnstatistical analysis of results. A total of 15 experiments were conducted at conditions of reactionrntemperature 50, 60 and 70rn3rnC, molar ratio of hydrogen per oxide to oil 1.1, 1.4 and 1.7 and 3, 4.5rnand 6 hours of reaction time. From the analysis of experimental results, the individual andrninteraction effects were studied and the optimal epoxidation reaction process conditions, whichrnwill maximize the percentage of conversion and selectivity were found to be 63rnornÂ°C reactionrntemperature, 1.4:1 molar ratio of hydrogen per oxide to oil and 4 hours of time reaction, whichrngave 70.9% and 90.07 percentage of conversion and selectivity respectively. The product ofrnepoxidized podocarpus falcatus oil were characterized by identifying the structure, functionalrngroup and composition of podocarpus falcatus seed oil, in comparison to epoxidized podocarpusrnfalcatus oil, using Fourier Transform Infrared Spectroscopy and proton Nuclear magneticrnresonance spectroscopy.
