FIELD: technological processes.
SUBSTANCE: present invention relates to a method of production of standard liquid SLR-3 for testing rubber and industrial rubber articles by adsorption refining of a distillate product extracted from oil of a naphthenic base characterized by that the distillate product used is a distillate with the temperature boiling limits of 360-440 °C, which been mixed with a solvent with the boiling limits of 80-120 °C is subjected to adsorption cleaning in a stationary layer of a pore aluminosilicate adsorbent with the specific pore volume not less than 0.75-0.85 cm3/g at the weight ratio of adsorbent:distillate of 1.0:1.5-2.3, the volume ratio of solvent:distillate of 1.0-8.0:1.0.
EFFECT: technical result of this invention is providing stable technology of producing ecologically clean domestic standard liquid SLR-3 to obtain the required quality parameters.
