Nucleophilic addition reactions (AN) to carbonyl compounds
Nucleophilic addition to alkynes is initiated by the action of a negatively charged species, the nucleophile. In general, the catalyst for such reactions is bases. General scheme of the first stage of the nucleophilic addition reaction: Typical reactions

Thermodynamics of Gibbs adsorption Rules for writing colloidal micelles
Kuznetsova E.S. and Buryak A.K. carried out a comparison of the thermodynamic characteristics of the adsorption of amino acids and their associates. The work investigated the influence of the structure of amino acids, their dimers and associates with eluent components on their adsorption on the surface
Phase equilibrium is characterized
Description of phase equilibrium is one of the most important tasks when calculating separation processes. Knowledge of equilibrium conditions allows not only to fundamentally resolve the issue of the possibility of separating a multicomponent mixture by methods of rectification, absorption, etc.
