Multiple Unsaturated Poly(urethane-Ester) Containing Epoxy Residues
ISBN: 9783659436437 / Angielski / Miękka / 2014 / 216 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych (Bez gwarancji dostawy przed świętami) Merging of all the four unsaturation, epoxy, ester and urethane segments into one polymer chain has not received attention academically and technically. Certain properties of thermoplastics may also be improved via blending or addition to an unsaturated resin is another possibility. In order to improve certain properties of such reported polymers their blending with commercial vinyl esters (epoxy resin) such as vinyl ester epoxy resin may afford a commercially important material for wide industrial applications. Hence the present report comprises synthesis of poly (urethane-ester) having...

Preparation of Chitosan Nanoparticals Coated K- Fertilizers
ISBN: 9783659402494 / Angielski / Miękka / 2013 / 112 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych (Bez gwarancji dostawy przed świętami) In this study, chitosans was deacetylated with 45% sodium hydroxide under air atmosphere at 80 C for up to 3 hour, to obtain deacetylated chitosan DDA measure by potentiometer titration method. Deacylated chitosan polymerizing methacrylic acid (DDCSPMAA) nanoparticle is an interesting material for use in controlled release for K fertilizers. In this work chitosan nanoparticles were obtained by polymerizing methacrylic acid for the incorporation of potassium chloride for potassium(K) fertilizers. The interaction and stability of chitosan nanoparticle suspensions containing K was evaluated by...

Studies on Chalcones and Pyrazolines of Medicinal Interest
ISBN: 9783639713596 / Angielski / Miękka / 2014 / 112 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych (Bez gwarancji dostawy przed świętami) The synthesis of chalcone system -C=C-C=O is relatively easy to prepare, usually highly reactive and are starting point of preparation of various bioactive compounds. This, -unsaturated ketones (chalcones) can be synthesized by Claisen-Schmidt condensation of different aromatic aldehydes with ketone and their cyclization with hydrazine hydrate in basic condition. Numerous pyrazoline derivatives have been found to possess considerable biological activities, which stimulated the research activity in this field. Amongst all the nitrogen containing five member heterocycles, it have proved to be...

Kinetic and Thermodynamic study of Adsorption of Ionic Dyes
ISBN: 9783659743177 / Angielski / Miękka / 2015 / 260 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych (Bez gwarancji dostawy przed świętami) Kinetic and thermodynamic study of removal of ionic dyes on low cost adsorbents and their derivatives. Four ionic dyes belonging to different classes were selected. The locally available low cost materials like raw agricultural wastes, carbonized agricultural wastes, surfactant modified agricultural wastes, surfactant modified agricultural waste carbon, low cost clays and low cost nanoadsorbents were evaluated for the adsorption of dyes from simulated dye effluent containing dyes. The effect of experimental conditions like effect of concentration, pH, temperature and reaction time were...
