Paraffin is unaffected by most common chemical reagents but burns readily. [8] Its heat of combustion is 42 MJ/kg. [9] The hydrocarbon C 31 H 64 is a typical component of paraffin wax. Paraffin wax is an excellent electrical insulator, with a resistivity of between 10 13 and 10 17 ohm-metre. [10]
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 ).
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.
Petroleum jelly, petrolatum (/ ˌ p ɛ t r ə ˈ l eɪ t ə m /), white petrolatum, soft paraffin, or multi-hydrocarbon, CAS number 8009-03-8, is a semi-solid mixture of hydrocarbons (with carbon numbers mainly higher than 25), [1] originally promoted as a topical ointment for its healing properties. [2] Vaseline has been an American brand of ...
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.
Kerosene, or paraffin, is a combustible hydrocarbon liquid which is derived from petroleum. It is widely used as a fuel in aviation as well as households. Its name derives from κηρός (kērós) meaning "wax", and was registered as a trademark by Nova Scotia geologist and inventor Abraham Gesner in 1854 before evolving into a generic trademark.
