“…However, depending on whether pure oxygen or air is used for oxidation, differences may exist in their technological details. 150,476,477 The produced EO is utilized as a decent disinfectant, sterilizing agent, and fumigant. Its ROP can proceed anionically or cationically but both of them generally give lower molecular weight products.…”

The demand for petroleum dependent chemicals and materials has been increasing despite the dwindling of their fossil resources. As the dead-end of petroleum based industry has started to appear, today's modern society has to implement alternative energy and valuable chemical resources immediately. Owing to the importance of lignocellulosic biomass for being the most abundant and bio-renewable biomass on earth, this critical review provides insights into the potential of lignocellulosic biomass as an alternative platform to fossil resources. In this context, over 200 value-added compounds, which can be derived from lignocellulosic biomass by using various treatment methods, are presented with their references. Lignocellulosic biomass based polymers and their commercial importance are also reported mainly in the frame of these compounds. The review article aims to draw the map of lignocellulosic biomass derived chemicals and their synthetic polymers, and to reveal the scope of this map in today's modern chemical and polymer industry.

“… 3 , 4 In ethylene epoxidation under industrial reaction conditions (200–250 °C, 15–20 bar), the initially metallic silver particles partially oxidize, forming a unique silver and oxygen containing surface for the catalytic reaction. 5 , 6 A profound influence of the chemical composition, size, and shape of nanoparticles on the catalytic performance has been demonstrated for many reactions including epoxidation reactions. 7 − 9 Furthermore, the impact of the catalytic reaction itself on the structure of the catalyst particles, resulting in dynamic behavior, has been emphasized.…”

Reversible Restructuring of Silver Particles during Ethylene Epoxidation

et al. 2018

The restructuring of a silver catalyst during ethylene epoxidation under industrially relevant conditions was investigated without and with vinyl chloride (VC) promotion. During non-VC-promoted ethylene epoxidation, the silver particles grow and voids are formed at the surface and in the bulk. Electron tomography highlighted the presence of voids below the Ag surface. A mechanism is proposed involving reconstruction of the silver lattice and defect sites induced by oxygen adsorption on the external surface and grain boundaries, which finally create pores. Promotion of the catalytic reaction by VC suppresses to a significant extent void formation. The use of VC also redisperses silver particles, initially grown during ethylene epoxidation without VC. This process is rapid as the average size decreased from 172 to 136 nm within 2 h. These insights emphasize the dynamic nature of the silver particles during the ongoing ethylene epoxidation reaction and indicate that particle size and morphology strongly depend on reaction conditions.
