The main source of coal tar is the carbonization of coal, a process in which coal is heated in the absence of air to produce coke, gases, and various by-products, including coal tar. This viscous, black liquid is rich in organic compounds and is primarily obtained from the by-products of coke production in steel manufacturing. Coal tar can also be derived from the destructive distillation of other organic materials, but its primary industrial source remains coal.
Coal tar is a complex mixture of organic compounds derived from the distillation of coal. It contains various hydrocarbons, phenolic compounds, and heterocyclic compounds. The specific composition of coal tar can vary depending on the source and method of production.

The main and obvious difference is one is coal based and the other comes from a pine tree. Studies have shown that coal tar is a Group 1 carcinogen, meaning it causes cancer at levels higher than 5%, so pine tar is a good alternative. It also smells great!
The two main types of creosote are made from wood-tar and coal-tar. Creosote is distilled from these different types of tar and used for varying purposes such as astringent, laxative, and anti-septic.
The flash point of coal tar enamel is typically around 500°F (260°C). This represents the temperature at which the enamel can ignite and produce a flame when exposed to a source of ignition.
