METHOD OF INTEGRAL MANIFOLDS IN QUALITATIVE STUDIES OF REACTIVE RECTIFICATION

First integrals are obtained for the dynamic systems of nonreactive re ctification and rectification with a chemical reaction of the general type. The integrals are independent of the specific mathematical model s describing these processes. The use of integral manifolds in the qua litative studies of these processes made it possible to reduce the dim ension of the dynamic systems. The use of integral invariants is exemp lified in the qualitative study of a batch reactive rectification desc ribed by two dynamic systems. Extractive rectification is studied in t erms of integral manifolds.
