The Synthesis of Methacrylic Esters by Carboxylation Reaction of Methylacetylene. I. Methyl Methacrylate; Reaction Conditions and Products

Synthesis of MgO Nanoparticales and Identificationof Their Destructive Reaction Products by 2-Chloroethyl Ethyl Sulfide

Nanocrystalline magnesium oxides were prepared by sol–gel method and were characterized by X-ray diffraction, N2-BET, SEM and infrared spectroscopy techniques. The results confirmed the formation of Nano- MgO materials with crystallite size in range of 5-20 nm and surface areas of 336-556m2/g. The product has been tested as destructive adsorbent for the decontamination of (2-chloroethyl) et...

the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...

Association Behavior of Poly (methyl methacrylate-b-methacrylic acid-b-methyl methacrylate) in Aqueous Medium

—ABA type tri-block amphiphilic polyelectrolyte consisting of poly(methyl methacrylate-block-methacrylic acid-block-methyl methacrylate) (P(MMA-b-MAA-b-MMA)) was synthesized by atom transfer radical polymerization technique (ATRP) and the self-assembly behavior of the polymers in aqueous solution was studied over the course of neutralization. Combination of potentiometric and conductometric tit...
