Reactant vs solvent
Often, reactivity and reaction mechanisms are pictured as the behavior of isolated molecules in which the solvent is treated as a passive support. However, the nature of the solvent can actually influence reaction rates and order of a chemical reaction. Performing a reaction without solvent can affect reaction-rate for reactions with bimolecular mechanisms, for example, by maximizing the concentration of the reagents. Ball milling is one of s… WebA polyurethane coating is a versatile product with many advantages upon other coating systems. A major disadvantage of classical, solvent based polyurethane coatings, are the volatile organic compounds (VOCs) present in the wet state. New regulations force formulators to keep the VOC content below 350 g/l. Recent developments dealt with this ...
