Investigation of the influence of thiocarbamide in the process of carbamide deparaffinization

The influence of thiocarbamide in the process of carbamide dewaxing was inv estigated. The dependence of separated paraffins on the quantity of thiocar bamide was examined experimentally. It was determined that the separation o f paraffins becomes equal to zero when moles of carbamide and thiocarbamide in water-isopropyl alcohol solution are equal. The low-temperature qualiti es (the temperature of dimness and freezing) of dewaxed fuels were also exa mined. By using infrared spectroscopy methods, the compound of received par affins was investigated.
