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 ]
a waxy fraction of petroleum commonly used to make candles (UK: paraffin wax) paralytic extremely drunk (slang) relating to or affected by paralysis park: a tract of ground kept in its natural state, about or adjacent to a residence, as for the preservation of game, for walking, riding, or the like (esp. Scotland) a pasture or field
Natural wax was largely replaced for the making of waxed paper (or paraffine paper) after Herman Frasch developed ways of purifying paraffin and coating paper with it in 1876. [2] Waxed paper is commonly used in cooking for its non-stick properties, and wrapping food for storage, such as cookies, as it keeps water out or in.
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.
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 modern English-speaking world, the term crayon is commonly associated with the standard wax crayon, such as those widely available for use by children. Such crayons are usually approximately 3.5 inches (89 mm) in length and made mostly of paraffin wax. Paraffin wax is heated and cooled to achieve the correct temperature at which a usable ...
Paraffin wax, a white or colorless soft solid (also in liquid form) that is used as a lubricant and for other applications; Liquid paraffin (drug), a very highly refined mineral oil used in cosmetics and for medical purposes; Alkane, a saturated hydrocarbon; Kerosene, a fuel that is also known as paraffin
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.
