METHOD FOR PRODUCTION OF STANDARD LIQUID SLR-2 FOR TESTING RUBBER AND INDUSTRIAL RUBBER ARTICLES Russian patent published in 2016 - IPC C10G25/00 

FIELD: technological processes.

SUBSTANCE: present invention relates to a method of production of standard liquid SLR-2 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 boiling limits of 450-520 °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 an aluminosilicate adsorbent with the specific pore volume not less than 0.75-0.85 cm³/g at the weight ratio of adsorbent:distillate of 1.7-3.2:1, the volume ratio of solvent:distillate of 4-10:1.

EFFECT: technical result of this invention is providing stable technology of producing ecologically clean standard liquid SLR-2 to obtain the required quality parameters.
