Compared to the previous Lewis acid catalyzed synthesis of olefins, our setup allows the use of benign and abundant transition metal triflate catalysts as well as various alcohols, esters and ethers as substrates.

Naphtha from low temperature Fischer−Tropsch (LTFT) synthesis is rich in n-paraffins, but it also contains alcohols and olefins. The highest ether yield (54%) was obtained at 300 °C, 1 MPa, and WHSV of 1 h−1 (unoptimized conditions). Calculations are provided to show that plug flow behavior was ensured under operating conditions resulting in a liquid phase. The influence of flow rate on linear α-olefin, aldehyde, and other side-product formation is provided (Table S5). Automated Serendipity with Self-Optimizing Continuous-Flow Reactors.

Write chemical reaction for the preparation of phenol from chlorobenzene. The main side-products were aldehydes and olefin dimers. Why is Ka2 << Ka1 for H2SO4 in water? Write the mechanism of acid-catalysed dehydration of ethanol to yield ethene. For reproduction of material from all other RSC journals. and supercritical CO Improvement of furanic diether selectivity by adjusting Brønsted and Lewis acidity. Information. These alcohols and olefins can be converted into linear fuel ethers and olefin dimers to improve the overall yield and quality of distillate from LTFT refining.
