N-Substituted succinamic acid beta-sitosteryl ester derivatives were prepared and evaluated. Compounds 1 and 2 were prepared in 76-92% yields by the reaction of beta-sitosterol and succinic anhydride, followed by the activation of the resulting acid compound 1 by thionyl chloride or methyl chloroformate, and finally by amination with appropriate amines. Compound 2a (DANA87) was also easily obta...

UNLABELLED The ferulic acid (4-hydroxy-3-methoxy-cinnamic acid) is a phenolic compound with important antioxidant effects and which nowadays is being extensively studied for his potential indications in inflammatory and neurodegenerative diseases, hypertension, atherosclerosis, etc. AIM The synthesis of new ferulic acid compounds with potential antioxidant activity. MATERIAL AND METHODS The...

Non-rechargeable batteries with a life of 20 years and more are required today for many smart metering and AMR applications in the US. Tadiran's non-rechargeable lithium thionyl chloride batteries offer a proven life of 25 years. Kohler's new touchless commercial faucet was designed to run even 30 years on a hybrid lithium battery. Similar requirements exist for wireless sensor networks. They c...

An alternative and effective route to prepare conducting polyaniline-grafted reduced graphene oxide (PANi-g-rGO) composite with highly enhanced properties is reported. In order to prepare PANi-g-rGO, amine-protected 4-aminophenol was initially grafted to graphite oxide (GO) via acyl chemistry where a concomitant partial reduction of GO occurred due to the refluxing and exposure of GO to thionyl...

One of the major hurdles in utilization metallic lithium anodes is understanding Li+ transfer kinetics through solid electrolyte interface (SEI) addition to Li oxidation. Electrochemical impedance spectroscopy (EIS) combined with temperature variation provides deeper comprehension and reveals kinetic parameters individual processes separately. In this study, we report temperature-dependent EIS ...

The degradation patterns of bacterial poly-3-hydroxybutyrate (PHB) in chloroform solution under the action thionyl chloride presence zinc were studied. When 2.5.mol and 100 mmol introduced into 25 PHB, a decrease molecular weight polymer was observed. During reaction, relatively rapid noted first hour experiment; thus, values weight-average decreased from 840 kDa to 483, 167, 58.6, 16.7 after 1...

substituted schiff bases (hydrazones) 5a-j have been prepared from the starting material 2-chloro pyridine-3-carboxylic acid 1 by a sequence of reactions like reaction with 2-amino-6-nitro benzothiazole (ullamann condensation), thionyl chloride, hydrazine hydrate and different aromatic aldehydes. on cyclocondensation of 5a-j with thioglycolic acid in dry 1,4-dioxane furnished desired compounds ...
