FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing silica gel, which includes mixing, gelling, drying, washing and drying, which is carried out using an automated method and is carried out successively in a sealed container, wherein drying is carried out at temperature of 60-70 °C for 6-7 hours, followed by washing with aerated water to achieve content of salts in water <8 mg/l and drying with a stream of heated air with smooth increase in temperature, carried out in two steps, first to temperature of 80-120 °C for 5-6 hours and second to temperature 120-200 °C for 8-10 hours.
EFFECT: obtaining silica gels of a given fraction and moisture level.
