The Kinetics and Mechanisms of Substitution Reactions of Trans-[Co(en)2CNCl]+ in Binary Mixed Solvent
The kinetics and mechanisms of the substitution reactions of trans-[Co(en)2CNCl]+ with unidentate anions, , CN¯, I¯, , Br¯ and SCN¯ in 60% v/v DMF-H2O binary solvent at 40.0±0.2 °C were studied spectrophotometrically. An Id mechanism was assigned for the replacement of chlorine by , CN¯ and I¯, an Ia one for...

15 صفحه اولFormulation development and evaluation of diclofenac sodium injection using benzyl alcohol (co-solvent), mixed solvency concept
Introduction: Mixed solvency is a concept of solubilization of the material. For producing new formulation, especially in the form of injection it is essential to solubilize the active pharmaceutical ingredients (API) in the solvent and that must be stable throughout the shelf life. Aqueous solubility of raw materials is important for injection formulation, but in some cases if the drug is not ...
متن کاملKinetics of Benzyl Chloride Production in a Bench Reactor Under Pressure with Stirrer (TECHNICAL NOTE)
Benzyl chloride is economically one of the most important starting materials for a large number of industrial syntheses. Far too much money is now spent to buy and import this valuable product. The production of benzyl chloride has been recognized as one of our national projects and budgeted by the National Iranian Petrochemical Organization in order to economize on the country’s foreign exchan...
