Моделювання процесів гідратації та структурування етанолу в умовах обробки ДІВЕ
Abstract
Due to the development of technologies the production of various substances and improvement of existing water-alcohol mixtures are widely used in various industries. In conventional devices energy is uniformly distributed throughout the size and that is why the main part of it falls on the technologically useless circulation of interacting components. The application of processes and devices, based on the principle of discrete input of energy, is devoid of these deficiencies and allows to enhance significantly the technological parameters of the process, for example, to reduce the energy intensity of output compared to conventional devices. This article describes the mechanism of mixing of water and alcohol in obtaining water- alcohol mixtures under processing conditions of discrete input of energy. The article represents the results of modeling of hydration processes and structuring of ethanol by the methods of computational chemistry (molecular dynamics). The modeling showed that the hydrogen bond in water-alcohol mixtures is formed: - If the distance to the hydrogen donor is less than 3,2 Å; - The angle of the covalent bond of donor and acceptor is less than 1200. It was found that the water-alcohol mixture in processing yields to the influence of high-frequency hydrodynamic vibrations, angular velocities and large transverse strains, which allow obtaining mixtures with a high degree of hydrationПроведено моделирование процессов гидратации и структурирования этанола.
