Potential one-pot synthesis of spherical magnesium silicate powder by mechanical milling

چکیده

Synthetic magnesium silicate finds applications in adsorbents, catalysis, pharmaceuticals, foods, cosmetics, and oil industry. This study introduces a method for potential one-pot preparation of narrowly sized, spherical powders. After initial synthesis by precipitation from sulphate sodium metasilicate solutions, the precursor was ball-milled with two immiscible liquids, forming particle-loaded emulsion. Hexane formed continuous phase; droplet phase either acetonitrile, methanol, or water-methanol mixtures. Suspended particles were refined, their fragments became trapped droplets, where they eventually compacted into composite spheres. Prepared powders characterized using scanning electron microscopy, nitrogen sorption, low angle laser light scattering. The synthesized exhibited narrow size distributions modes 3.3 to 92 ?m. showed an enhanced flowability had specific surface areas comparable higher than precipitated

Synthesis of CuFeS2 Nanoparticles by One-pot Facile Method

Monodisperse copper-iron-sulfide (CuFeS2) nanoparticles as the infrared light absorbing material (chalcopyrite, 0.65 eV), were synthesized based on facile, one step heating up method, by dissolving of CuCl, FeCl3 and SC(NH2)2 as precursors in oleylamine (OLA) alone or in combination with oleic acid (OA) and 1-octadecene (ODE) as solvent. The phase, size, morphology, and size distribution were c...

One-pot Synthesis of Polysubstituted Indolizine Derivatives

An efficient approach to the synthesis of 1,2,3-trisubstituted indolizines is described via one-pot reactions of pyridine and dialkyl acetylendicarboxylate in the presence of ethyl 2-chloroacetoacetate in MeOH at room temperature. The corresponding 1, 2, 3-trisubstituted indolizines may be useful building blocks for the construction of complex indolizine derivatives.

A Modified-One Pot Synthesis of Diaminoglyoxime

The one pot reaction of glyoxal and hydroxylamine hydrochloride in aqueous sodium hydroxide was found to be a safe and inexpensive method for the preparation of diaminoglyoxime. By increasing stoichiometric ratio of the hydroxylamine hydrochloride and decreasing the solvent volume, the product yield increased considerably (~ 70%).
