Paraffin wax (or petroleum wax) is a soft colorless solid derived from petroleum, coal, or oil shale that consists of a mixture of hydrocarbon molecules containing between 20 and 40 carbon atoms. It is solid at room temperature and begins to melt above approximately 37 °C (99 °F), and its boiling point is above 370 °C … See more Paraffin wax is mostly found as a white, odorless, tasteless, waxy solid, with a typical melting point between about 46 and 68 °C (115 and 154 °F), and a density of around 900 kg/m . It is insoluble in water, but soluble in See more Paraffin wax was first created in 1830 by German chemist Karl von Reichenbach when he attempted to develop a method to efficiently separate and refine waxy substances naturally occurring in petroleum.

WebParaffins, also known as alkanes, are saturated compounds that have the general formula C n H 2n + 2, where n is the number of carbon atoms. The simplest alkane is methane (CH 4 ), which is also represented as C 1. Normal paraffins (n-paraffins or n-alkanes) are unbranched straight-chain molecules. What is paraffin used for?
