Annotation

The article recommends optimal parameters for the process of obtaining liquid paraffin based on hexane, which is a secondary product of the chemical industry. Comparing the composition of domestic and "foreign analog" aprotic solvents, it is found that the efficiency is higher in solutions with a relatively large amount of the main component, the concentration output is 3.2% higher in the "foreign analog" solvent with the same consumption of two apolar collectors, the content of KCl in the float product due to the influence of local liquid paraffin the amount was found to be 0.9% more.
