METHOD OF PRODUCING SOLS AND SUSPENSIONS Russian patent published in 2020 - IPC B01J13/00 B82Y40/00 B01D45/00 

FIELD: chemistry.

SUBSTANCE: invention relates to chemical industry and pharmaceutics and can be used in making means of accelerated delivering solid substance, paint and lubricant materials, as well as in cleaning air from suspended particles. First, an aerosol of solid particles and an aerosol of particles formed by the fluid. As a result of contact of obtained aerosols in cell 1, an aerosol of particles of sol or suspension is obtained, in which solid particles are suspended in particles of fluid medium. Aerosol particles of the sol or suspension are then deposited to obtain macroscopic amounts of sol or suspension under the action of inertia by means of cyclone filter 4. Deposition can also be carried out under the action of gravitational or electric field, acoustic action or freezing. Aerosol of particles of sol or suspension can be recycled into cell 1 and used as an aerosol of particles formed by fluid medium. Obtained sol or suspension can be used as a fluid medium. Fluid may additionally be fed into cell 1 from reservoir 6. Fluid contains water, ethanol or a mixture thereof. Solid particles are carbon nanotubes, silver or iron nanoparticles encapsulated in a carbon shell. Fluid medium or particulate aerosol can additionally contain a surfactant, for example TRITON X-100, TWEEN 20, sodium deoxycholate, sodium dodecyl sulphate (SDS), ribonucleic or deoxyribonucleic acid or mixtures thereof. Obtained suspension can be additionally separated by flow gel chromatography.

EFFECT: reduced time of preparation of stable sols or suspensions with minimum degree of defectiveness, as well as fragmentation and agglomeration of solid particles.
