Conclusions 1. Adsorption purification was carried out of the initial diesel distillate for the purpose of obtaining raw material for the manufacture of dearomatized liquid paraffins. 2. An optimal regime of carbamide deparaffinization of purified raw material was found under conditions of mechanical stirring; it was established that the optimal conditions of carrying out the process are: ratio of carbamide to raw material, 100%; consumption of solvent for diluting raw material,50%; amount of solvent necessary for washing the complex, 300% based on carbamide; contact time of carbamide with raw material, 30 min; temperature of complex formation, +20°C. 3. It was shown that at the found optimal regime of the process 16% liquid paraffin having an aromatic hydrocarbon content of 0.5% and a component of arctic diesel fuel having solidification point of −56°C can be obtained.
