FIELD: chemistry.
SUBSTANCE: invention can be used in chemical industry. A precipitated silicic acid with dibutyl phthalate number in anhydrous state, i.e., DBP number, in the range of 210 to 270 g/100 g; the value d50 after one minute of ultrasonic exposure in the range of 220 to 400 mcm; amount of particles with size smaller than 200 mcm after one minute of ultrasonic exposure less than 35 vol.%, is used to produce absorbates.
EFFECT: obtained absorbates have good flowing properties and processability.
