Review on Effect of Catalysts in Preparation Methods of Chalcone
Abstract: This review covers effect of some catalysts in preparation methods of chalcone compounds. These compounds are responsible for the coloration of flowers due to the presence of the cascade. The molecules of the compound become highly photo-acetic and thus are ideal chromophores. Recently, a number of studies have been conducted describing the process of separating chalcones from different parts of plants such as roots (roots), buds, leaves (leaves), flowers, seeds …

Review on Effected Factors of Type of Products
Abstract: This survey covers effect of some factors in type of products in any reaction. A catalyst speeds up a chemical reaction, without being consumed by the reaction. Catalysts that used in any reaction, as it affects the nature of the product, its quantity, purity, color, degree of stability, the physical and chemical properties, the resulting isomers, the essential and secondary resulted of each reaction, and even the reaction conditions. It …
