Kinetic model for extraction of extractive substances from vegetable raw materials

Abstract

The exponential equation of diffusive kinetics for extraction of substances from vegetable raw materials with the correction parameter has been proposed. Algorithms for calculation have been considered and the comparative assessment of molecular diffusion coefficients for process of birch bark extraction by the traditional method and taking into account interpar-tial interactions in system, has been performed. With participation of components of vegetable raw materials, diffusive kinetic model adjusted for non-ideal interphase processes has been obtained.
