Paraffin candle. 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 ...

A major component of beeswax is myricyl palmitate which is an ester of triacontanol and palmitic acid. Its melting point is 62–65 °C (144–149 °F). Spermaceti occurs in large amounts in the head oil of the sperm whale. One of its main constituents is cetyl palmitate, another ester of a fatty acid and a fatty alcohol.

On distillation in a current of superheated steam, ozokerite yields a candle-making material resembling the paraffin obtained from petroleum and shale-oil but of higher melting-point, and therefore of greater value if the candles made from it are to be used in hot climates.
C 3 H 5 (O 2 C(CH 2) 16 CH 3) 3 + 3 NaOH → C 3 H 5 (OH) 3 + 3 NaO 2 C(CH 2) 16 CH 3. This process is the main industrial method for producing glycerol (C 3 H 5 (OH) 3). Some soap-makers leave the glycerol in the soap. Others precipitate the soap by salting it out with sodium chloride.
Hentriacontane, also called untriacontane, is a solid, long-chain alkane hydrocarbon with the structural formula CH 3 (CH 2) 29 CH 3.It is the main component of paraffin wax.. It is found in a variety of plants, including peas (Pisum sativum), Acacia senegal, Gymnema sylvestre and others, and also comprises about 8–9% of beeswax.
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). Depending on chain ...
