How it is made

By far the largest amount of saturated hydrocarbons is obtained from the natural sources natural gas and petroleum, either by isolation, e.g., fractional distillation, or by suitable conversion reactions. Additional sources include various products derived from coal processing or biomass conversion reactions, e.g., Fischer-Tropsch synthesis. Saturated hydrocarbons that are unavailable from natural sources or for laboratory purposes are produced by special synthesis or by conversion processes. (Saturated hydrocarbons)
