Homogeneous catalysis heterogeneous catalysis is the petrochemical alkylation process, where the liquid reactants are immiscible with a solution containing the catalyst. Heterogeneous catalysis offers the advantage that products are readily separated from the catalyst, and heterogeneous catalysts are often more stable and degrade much slower than homogeneous catalysts. However, heterogeneous catalysts are difficult to study, so their reaction mechanisms are often unknown. Enzymes possess properties of both homogeneous and heterogeneous catalysts. As such, they are usually regarded as a third, separate category of catalyst. Homogeneous catalysis In chemistry, homogeneous catalysis is catalysis in a solution by a soluble catalyst. Homogeneous catalysis refers
A Man Called Sloane A Man Called Sloane A Man Called Sloane is an American secret agent adventure television series that aired on NBC during the 1979-1980 television season. It was a Woodruff Production in association with QM Productions, and became the final series produced by Quinn Martin's company to debut ("Barnaby Jones" was the last remaining QM program to be cancelled, in 1980). It is also one of only three QM series not to have an announcer accompanying the opening titles (the only other one is "Quinn Martin's Tales Of The Unexpected"), one of the two not to display a copyright notice at
