Synthesisof Zirconium Containing Mesoporous Material for the Efficient Catalytic Esterification of Benzyl Alcohol and Acetic Acid
This research focuses on the synthesis of metalcontainin gmesoporous silica for catalytic esterification of benzyl alcohol with acetic acid. In this study Zr-containing MCM-41 with different molar ratios of Si/Zr were synthesized successfully. It is observed that the structural ordering of Zr- MCM-41varies with the Si/Zr ratio, and highly ordered mesoporous molecular sieves could be obtained for a Si/Zr molar ratio larger than 5. Calcination may significantly improve the structural regularity. In esterification reaction of benzyl alcohol with acetic acid, the benzyl alcohol conversion over all the Zr-MCM-41catalysts linearly increases with increasing the reaction temperature and selectivity to benzyl acetate was 100 %. The molar ratios of reactants also were investigated for final product yield; the molar ratio of acetic acid to benzyl alcohol can be 2:1 for high yield.
Synthesis and Applications of Isocyanate Free Polyurethane Materials
The manufacture of conventional polyurethanes include the use of isocyanates, which in turn require using toxic and hazardous phosgene. The safety devices are necessary to prepare these monomers. Therefore, the huge investment is inevitable for this process. Also, these monomers cannot be considered as environmentally friendly chemicals. The increasing global awareness for protection of environment from chemical pollutants has created a necessary demand for environmentally benign products. The reaction of cyclic carbonates (polycarbonates) with amines results in formation of hydroxyurethanes that can be taken into account as a unique reaction. This specific reaction has been investigated over last few years. Most chemists have been strongly attracted by this technique that is due to its potential application to prepare the green, non-toxic, non-sensitive towards moisture isocyanate free polyurethanes. This review is focused on the variety of catalysts used to prepare isocyanate free polyurethanes from five membered cyclic polycarbonates. Also, the reaction mechanism and kinetics for their synthesis have been discussed. In this review, the six-membered cyclic carbonates depicted the higher reactivity rather than five-membered cyclic carbonates for production of non-isocyanate polyurethanes. The various functions of isocyanate free polyurethanes in different fields such as coatings, construction and bio-composites have been summarized.
Calculation of Proton range in Some Organic Compounds Energies (1000-100000)keV
Theoretical study have been done to calculated the Range for protons in ten organic compounds which is: [ polypropylene(C3H6) ,Polycarbonate (C16H14O3), Mylar (C10H8O4), Polyvinylalcohol (C2H4O), Polyoxymethylene (CH2O), by using SRIM2013 program written by Mathlab language. the range calculated to protons for energy (1000-100000) keV , by using fitting equations and the semi empirical equation (Devise two equation), and we calculated the rate error and correlation coefficient betweenRange(SRIM) and Range(semi-emp) as seen in tables by using Excel program. The results are agreed with the SRIM 2013 program, so our results showed to be good.
