“…The purpose of this paper is mainly to show how vegetable oils could be modified by simple epoxidation reaction to further serve as renewable material feedstock. While fatty acid profiles of commodities such as sunflower, soy bean and canola oils are major lipid of interest in the world (Starostina et al, 2020), local commodity in Malaysia such as palm oil was also given consideration in this study.…”

Nowadays, major pollutions present in the environment are produced by non-degradable substances. Eventually, the use of non-degradable products will increase carbon footprint in the atmosphere. In this study, modifications of five vegetable oils into biobased epoxides are reported. The oils used in this study were commercial palm oil, rice bran oil, canola oil, soybean oil and sunflower oil. The vegetable oils were refluxed using formic acid and hydrogen peroxide at temperature ranges of 45 to 50˚C and 60 to 65˚C for seven hours in order to change the chemical structure of carboncarbon double bonds into oxirane rings. The mixture was then processed by liquid-liquid extraction to separate epoxide oil from liquid that was present during the reflux process. The obtained oils were then analyzed using ATR-FTIR and the presence of oxirane rings were observed at the wavelength ν=1080.79 cm -1 and 836.10 cm -1 for epoxidized palm oil, ν =1107.14 cm -1 and 841.11 cm -1 for epoxidized rice bran oil, ν =1050.13 cm -1 and 850.35 cm -1 for epoxidized canola oil, ν =1083.99 cm -1 and 825.03 cm -1 for epoxidized soybean oil and ν =1095.57 cm -1 and 820.16 cm -1 for epoxidized sunflower oil, respectively. Additionally, an absorption band at ν=1462 cm -1 was observed in all oil samples, indicating the presence of C-C oxirane. In future, these epoxidized oils can serve as a great potential as new starting materials for the synthesis of lipid biopolymers.

The analysis of research literature indicates that certain innovations are required in managing vegetable carbon-containing waste. A method of obtaining a new sorption material from vegetable waste of soya Glycine max (leaves, stalks, pod shucks), carbonized at the temperature from 200 to 400 °С in the anaerobic environment in an airtight steel container for 1 hour, is suggested. The criteria for evaluating the quality of a thermally activated sorption material were presented with the following parameters: bulk density; mass yield and volume yield of the sorption material; combustion loss degree. The elemental analysis has demonstrated that with the increase in the treatment temperature the increase of the carbon content from 58 % (Т = 200 °С) to 65.6 % (Т = 400 °С) is registered; and the oxygen content is reduced from 37 to 24 %. The heat-treated samples were researched by means of a scanning electron microscope. The porosity type of all the obtained sorption materials is a macroporous body with a pore radius of over 100–200 nm. The general view of the carbon-containing materials has the following morphological characteristics: bulges on the outer surface, and the channel structure of macropores, typical of carbonized materials. The amount of functional groups was determined by the Boehm method. With increase in the treatment temperature, the amount of carboxyl groups on the surface of carbon-containing materials is increased, while the amount of lactone groups is decreased, which is due to the burning-off of organic matter. The sorption capacity for methylene blue dye (from 35.0 to 81.85 mg/g) was determined during heat treatment in the mentioned temperature range.
