FIELD: technological processes.
SUBSTANCE: present invention relates to a method of production of standard liquid SLR-1 for testing rubber and industrial rubber articles using finely cleaned residual distillate extracted from paraffin oil raw material characterized by that the said residual distillate in a mixture with a solvent 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:residual distillate of 1.3-1.5:1, the volume ratio of solvent:residual distillate of 4-6:1.
EFFECT: technical result of this invention is providing stable technology of producing ecologically clean domestic standard liquid SLR-1 to obtain the required quality parameters.
