Naphtha

Mixtures labelled naphtha have been produced from natural gas condensates, petroleum distillates, and the distillation of coal tar and peat. In different industries and regions naphtha may also be crude oil or refined products such as kerosene. Mineral spirits, also historically known as "naphtha", is not the same chemical.
