Ionothermal synthesis of aluminophosphate molecular sieves
Effects of ionic liquid structures on the aluminophosphate molecular sieve products in ionothermal synthesis process were investigated. The results showed that the possible structure-directing effect of ionic liquid might exist during ionothermal synthesis. Microwave heating was introduced into the ionothermal synthesis, which led to a fast and safe process for preparation of molecular sieves. ...
متن کامل5-sulfosalicylic acid as an efficient organocatalyst for environmentally benign synthesis of 2-substituted benzimidazoles
A water soluble, Bronsted acid, 5-sulfosalicylic acid as an efficient organocatalyst was used for the synthesis of physiologically active 2-substituted benzimidazole derivatives from o-phenylenediamine and aromatic aldehydes in ethanol at reflux condition. Cost-effectiveness, use of non-hazardous solvents, metal free and commercially available catalyst, single-step, environmentally fri...
متن کاملAn Efficient and Environmentally Benign Chemical Synthesis of Testolactone
Testolactone was obtained commercially by microbial transformation of either testosterone or progesterone and also synthetically, albeit in low yield. The only chemical synthesis of 1 so far described in the literature starting from dehydroepiandrosterone (2) is shown in Scheme 1. The strategy followed in this synthetic approach consisted in the initial formation of the lactone ring by a Baeyer...
متن کاملEnvironmentally benign synthesis of virus-templated, monodisperse, iron-platinum nanoparticles.
The use of an engineered variant of a plant virus, Cowpea mosaic virus (CPMV), as a template for directed mineralization provides an environmentally benign route to monodisperse iron-platinum nanoparticles of approximately 30 nm diameter.
متن کاملEffect of water on the ionothermal synthesis of molecular sieves.
AlPO4-11 and AlPO4-5 molecular sieves are ionothermally prepared without addition of water by using anhydrous starting materials, such as NH4H2PO4, pseudoboehmite (AlOOH), and NH4F. The synthesis appears to be an autocatalytic process. Water has a remarkable effect on the synthesis process. Addition of reagent quantities of water (H2O/Al = 1, molar ratio) can enhance the crystallization kinetic...
