FIELD: physico-chemical methods. SUBSTANCE: microemulsion consists of (i) aqueous phase and dispersed micelles composed of water and polymer based on alkylacrylamide substituted by at least 1 mol % of quaternized tertiary aminomethyl groups and possessing standard viscosity at least 3.3 cpoise (25 C) as measured on addition of 10.8 parts of 10.87% sodium chloride aqueous solution to 10.0 parts of 0.2% aqueous polymer solution followed by agitation for 5 min, measurement being conducted on a Brookfield viscosimeter with UV adapter operated at 60 rpm, (ii) hydrocarbon phase in amount corresponding to its weight ratio to aqueous phase 1:(0.5-3), and (iii) a surfactant or surfactant mixture having hydrophilic-lipophilic balance approximately 8 to 12. Such microemulsions can be used for dehydrating dispersions with low content of suspended solids. EFFECT: increased dispersion dehydration efficiency. 10 cl, 2 tbl, 13 ex
