• Does heterogeneous catalyst improve epoxidation of sunflower oil?
  • Owing to the increasing demands for eco-friendly epoxides derived from vegetable oils, much effort has been made regarding the epoxidation of sunflower oil in recent years. The aim of this study was to optimize the process parameters for the epoxidation of sunflower oil using a heterogeneous catalyst.
  • How to optimize the process parameters for epoxidation of sunflower oil?
  • The aim of this study was to optimize the process parameters for the epoxidation of sunflower oil using a heterogeneous catalyst. The optimal process parameters determined were agitation speed of 300 rpm, type oxygen carrier of formic acid, hydrogen peroxide to oleic acid molar ratio of 1.5, and catalyst loading 0.2%.
  • What is enzymatic epoxidation of sunflower oil?
  • With the purpose of using easily removable free fatty acid and to get the final product with a low acid value (AV), the enzymatic epoxidation of sunflower oil was conducted in the presence of Novozym 435 and short-chained butyric acid as an active oxygen carrier.
  • Can sunflower oil produce Epoxidized vegetable oil as palm oil?
  • However, there is not enough reported research conducted to produce epoxides from linoleic acid. This shows the potential of sunflower oil to produce epoxidized vegetable oil as palm oil. Sunflower oil is non-volatile oil produced from pressed seed sunflower. Sunflower oil is one of the five important vegetable oils produced worldwide .
  • What is epoxidation of vegetable oil?
  • Epoxidation is the chemical reaction that converts the carbon¨Ccarbon double bond into oxiranes (epoxides) using a variety of oxidizing agents. Various methods have been developed for the epoxidation of vegetable oils as follows: ? Homogeneous catalytic system by peroxyacids. ? Heterogeneous catalytic system by acidic ion exchange resins (AIERs).
  • How to convert sunflower oil derived linoleic acid to oxirane?
  • The optimal relative conversion to oxirane yield of sunflower oil derived linoleic acid was 63.9%, achieved through a 1:1 formic acid and hydrogen peroxide to linoleic acid molar ratio reaction with 0.2% zeolite as a catalyst and stirring speed of 300 rpm.
