“…Unsaturated fatty acids from plant oils and esters thereof (biodiesel) can be modified by the epoxidation of their double bond(s) to an oxirane ring. [337] The catalyst coating was applied to the microreactor by filling the glass capillary with a solution of TiO 2 (10 wt%) in ethanol. [336] The biphasic liquid-liquid epoxidation of fatty acid methyl esters (FAME biodiesel) has been performed in microreactors.…”

Biomass as a renewable and abundantly available carbon source is a promising alternative to fossil resources for the production of chemicals and fuels. The development of biobased chemistry, along with catalyst design, has received much research attention over recent years. However, dedicated reactor concepts for the conversion of biomass and its derivatives are a relatively new research field. Continuous flow microreactors are a promising tool for process intensification, especially for reactions in multiphase systems. In this work, the potential of microreactors for the catalytic conversion of biomass derivatives to value-added chemicals and fuels is critically reviewed. Emphases are laid on the biphasic synthesis of furans from sugars, oxidation and hydrogenation of biomass derivatives. Microreactor processing has been shown capable of improving the efficiency of many biobased reactions, due to the transport intensification and a fine control over the process. Microreactors are expected to contribute in accelerating the technological development of biomass conversion and have a promising potential for industrial application in this area.

“…However, the stability of TiO 2 coated capillary needs to be further developed since the catalyst is peeled off aer 3 h of time on stream (TOS). 163 Chavan and coworkers 62 produced epoxidized sunower oil (ESNO) with 91.1% conversion to oxirane oxygen by the combined use of ultrasonic bath and mechanical agitation as the equipment intensication. It was concluded that the product can be applied as a safe a The results are calculated by the titrimetric method as described in the analytical part.…”

“…Another titania using a study performed epoxidation of methyl oleate in a TiO 2 coated-wall capillary microreactor with H 2 O 2 , EDTA and formic acid, and no solvent, and achieved with a continuous operation 23 times higher reaction rate of epoxide production than with a batch reactor. However, the catalyst layer was slowly peeled off, reducing the performance [126].…”

The Lord of the Chemical Rings: Catalytic Synthesis of Important Industrial Epoxide Compounds

The epoxidized group, also known as the oxirane group, can be considered as one of the most crucial rings in chemistry. Due to the high ring strain and the polarization of the C–O bond in this three-membered ring, several reactions can be carried out. One can see such a functional group as a crucial intermediate in fuels, polymers, materials, fine chemistry, etc. Literature covering the topic of epoxidation, including the catalytic aspect, is vast. No review articles have been written on the catalytic synthesis of short size, intermediate and macro-molecules to the best of our knowledge. To fill this gap, this manuscript reviews the main catalytic findings for the production of ethylene and propylene oxides, epichlorohydrin and epoxidized vegetable oil. We have selected these three epoxidized molecules because they are the most studied and produced. The following catalytic systems will be considered: homogeneous, heterogeneous and enzymatic catalysis.
