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 ]
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
Structure of 2,3,4,5,6,8-hexachlorodecane, an example of a short-chained chlorinated paraffin (61% Cl by weight) Structure of 2,5,6,7,8,11,15-heptachloroheptadecane, an example of a medium-chain chlorinated paraffin (52% Cl by weight) Chlorinated paraffins (CPs) are complex mixtures of polychlorinated n-alkanes (paraffin wax).
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.
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.
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 ...
Wax emulsions based on beeswax, carnauba wax and paraffin wax are used in creams and ointments. The emergence of soybean waxes with varying properties and melt points has led to the use of vegetable wax emulsions in applications such as paper coatings, paint and ink additives, and even wet sizing for pulp and paper applications.
A pouch created using waxed cotton. Waxed cotton is cotton impregnated with a paraffin or natural beeswax based wax, woven into or applied to the cloth. [1] [2] Popular from the 1920s to the mid-1950s, the product, which developed from the sailing industry in England and Scotland, became commonly used for waterproofing.
