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), [ 2 ] and its boiling point is above 370 °C (698 °F). [ 2 ]
In the mid-1850s, James Young succeeded in distilling paraffin wax from coal and oil shales at Bathgate in West Lothian, and developed a commercially viable method of production. [34] The paraffin wax was processed by distilling residue left after crude petroleum was refined. Paraffin could be used to make inexpensive candles of high quality.
Liquid Paraffin in a glass bottle. Paraffin oxidation is a historical industrial process for the production of synthetic fatty acids. [1] The fatty acids are further processed to consumer products such as soaps and fats as well as to lubricating greases for technical applications.
Paraffin waxes are mixtures of saturated n- and iso- alkanes, naphthenes, and alkyl- and naphthene-substituted aromatic compounds. A typical alkane paraffin wax chemical composition comprises hydrocarbons with the general formula C n H 2n+2, such as hentriacontane, C 31 H 64. The degree of branching has an important influence on the properties.
In the mid-1850s, James Young succeeded in distilling paraffin wax from coal and oil shales at Bathgate in West Lothian and developed a commercially viable method of production. [27] Paraffin could be used to make inexpensive candles of high quality. It was a bluish-white wax, which burned cleanly and left no unpleasant odor, unlike tallow candles
Chlorinated paraffins (CPs) are complex mixtures of polychlorinated n-alkanes (paraffin wax). The chlorination degree of CPs can vary between 30 and 70 wt% . CPs are subdivided according to their carbon chain length into short-chain CPs (SCCPs, C 10–13 ), medium-chain CPs (MCCPs, C 14–17 ) and long-chain CPs (LCCPs, C >17 ).
With dry, cracked skin running rampant in the cold-weather months, investing in one of the best paraffin wax baths is an effective way to correct dryness in the hands, feet and elbows and create ...
Wax deposition or paraffin deposition refers to the accumulation of paraffin wax on the surface of a substance, typically a liquid or gas. This can occur in a variety of contexts, including the production and transport of oil and natural gas, the refining of petroleum products, and the storage and transport of chemicals.
