Naphtha is understood as diesel fuel or crude oil in Italy, Czech Republic, Slovakia, Serbia, Bosnia, Croatia, Slovenia and Bulgaria.Ligroin (also naphtha, petroleum spirit, petroleum distillate, gasoline-ligroin fraction), mixture of paraffin, naphthene and aromatic hydrocarbons (from C5 to C12) produced by distillation of crude or gas condensates (yield of 15-18% from feedstock weight), has the closest meaning in Russia.Distillation range — 120-240 °С; density — 0.785-0.795 g/сm3. Transparent yellowish fluid.Synonyms are Shellite (Australia), white gas (North America), white spirit or Coleman fuel.Major portion of ligroin produced during crude distillation is subjected to reforming for conversion into gasoline. However, a considerable portion thereof is used as feedstock to produce other chemical substances.It is heavier than gasoline and lighter than kerosene. Comparing to kerosene, ligroin differs by insignificant condensation in oil and higher evaporability upon slight heating. Storage conditions and handling rules are similar to gasoline.It was mainly produced as motor fuel for tractors. Ligroin contains no starting fractions. In consequence thereof it is difficult to start engine with the same; prior engine heating is required with use of starting fuel, such as gasoline.It has lost its importance in connection with tractor fleet conversion to diesel engines and is mainly used in instrument-making as filler of fluid instruments. Also used as fuel in spark-ignition and diesel engines, component of commercial gasoline, lighting kerosene and jet fuels; and solvent in paint-and-varnish industry.We have managed to find only «ligroin solvent TU 0272-001-59315437-2006 in quantity of 400 tons at price of RUR 15.5 k/ton» in the Russian market.
