catalysts Unique.

Homogeneous catalysts Unique, Divided Self After reaction.

What is a homogeneous catalyst? When we use the acid esterification catalysis for the solution of this course will mix perfectly with the reactant and product compounds. tSecara general, homogeneous catalysts are compounds that have the same phase as the reactants of chemical reactions take place.

Actually a lot of use of homogeneous catalysts in industry, ranging from the conventional, cheap sort of acid or base catalyst to organometalik compounds are expensive. Selectivity of reaction and reaction conditions are mild primary consideration homogeneous catalyst selection.

The main problem is often encountered in industrial and chemical synthesis using a homogeneous catalyst is the difficulty of doing the separation of catalyst from the product. The method used is the plural distillation or modify it kepolaran and material and energy-consuming large enough.

The dream of scientists and industrialists catalyst is a homogeneous catalyst that meets the economic requirements and easily separated after the reaction so that it can be used again. In August 2003, scientists from Brookhaven National Laboratory, R. Morris and Vladimir Dioumaev show such a homogeneous catalyst that can be settled after the reaction is complete hidrosililasi ketone compounds took place. Cation complex tungsten compounds that have weak bonds to the anion coordination is a problem-solving in these reactions.

The process is simple logic that is, before the reaction, the catalyst and the reactants dissolve completely perfect because it has the same kepolaran. However, as the process went, it was the product has a different kepolaran and the result is the separation of catalyst from the product itself. Another thing to note is the formation of two phases of the product and the catalyst material to form a kind of oil.

Indeed this technology can not generalized because of the reaction is the reaction of ketones hidrosililasi specific and does not use any solvent on the reaction. But this is really new and exciting discovery because it opens the opportunity to do further research, particularly the field of homogeneous catalysts.
