phase change, or PTC, some sort of that the transfer of reagent from one phase into another phase where reaction takes place, etc. makes it easy. phase change template special extremely heterogeneous. Reagents, Ionic, usually in an aqueous solution of soluble have, but in the absence of phase change in a phase of organic insoluble. This such as a detergent for the solubility of salts, to the organic phase act.

enjoying phase shift, etc. reactions are faster, etc. products, accessories less and transformations we have the higher also the need for solvents, expensive, or dangerous, that's all in a phase solve the other does not come. Use phase change in green chemistry much is used, because instead of using organic solvents from the water we use.

contrary to many, many more! phase change, the only special reaction water, or the water getaway, but in most reactions, liquid/gas and solid/liquid can also be used.
