The O-methylation of catechol is an effective method for the industrial production guaiacol used as important chemical. However, low conversion and poor catalyst stability are most critical issues that need to be addressed. Herein, with dimethyl carbonate was investigated over aluminophosphate (APO) catalysts, using a continuous-flow system produce guaiacol. APO catalysts were synthesized varyi...

We report on a room temperature (RT) sodium-sulfur (Na−S) battery based sodium anode, sulfurated poly(acrylonitrile) (SPAN) cathode and an electrolyte containing tetrakis(hexafluoroisopropyloxy) borate (Na[B(hfip)4]; hfip=hexafluoroisopropoxide) in mixture of ethylene carbonate (EC), dimethyl (DMC) fluoroethylene (FEC). The hfip anion as weakly coordinating (WCA) provides high anodic stability,...

A matrix of LiNi 0.5 Mn 0.3 Co 0.2 O 2 /graphite cells filled with 1.33 molal LiPF 6 in EC:EMC:DMC (ethylene carbonate: ethyl methyl dimethyl carbonate) (25:5:70 by volume) electrolyte and different weight percentages vinylene carbonate (VC) ethylene sulfate (DTD) additives underwent prolonged charge-discharge cycling at 20 °C 40 °C. The volume gas produced during formation cycle testing was me...
