Paraffin is a broad term that encompasses a group of waxy, solid hydrocarbons derived primarily from petroleum or shale oil. These hydrocarbons are alkanes, saturated hydrocarbons consisting of carbon and hydrogen atoms arranged in a straight or branched chain. The general formula for these is CnH2n+2, where “n” represents carbon atoms bonded with each other in the molecule.
Composition of Paraffin
Paraffin is a complex mixture of hydrocarbons, primarily consisting of straight-chain alkanes with carbon chain lengths ranging from 20 to 40 carbon atoms. The composition of paraffin wax can vary depending on the source of the crude oil and the refining process used.
The main constituents of paraffin wax are saturated hydrocarbons, specifically alkanes. These hydrocarbons have the general formula CnH2n+2. The most abundant hydrocarbons in paraffin wax typically have carbon chain lengths between 22 and 32.
In addition to alkanes, paraffin wax may contain small amounts of other hydrocarbons, such as alkenes and alkynes, as well as aromatic compounds and nitrogen, sulphur, or oxygen-containing compounds. These impurities affect its properties, like its melting point, colour, and odour.
The exact composition of paraffin wax may vary depending on its intended application. For example, paraffin wax used in candle-making may have a slightly different composition than in cosmetic products or industrial applications. Refining processes can be used to remove impurities and optimise the properties of the wax for specific applications.
History of Paraffin
The history of paraffin can be traced back to the early 19th century. Here is an overview of the history of paraffin:
Discovery of Paraffin
In the early 1800s, chemists and scientists began exploring the properties of petroleum, a naturally occurring substance found in underground oil fields. During this time, researchers discovered a waxy substance that separated from petroleum when distilled. This substance was named “paraffin” by German chemist Karl Reichenbach in 1830, derived from the Latin word “parum affinis,” meaning “lacking affinity” due to its low reactivity with other substances.
Industrial Production
In the mid-1800s, the industrial production of paraffin wax began. Scottish chemist James Young played a significant role in developing the process for extracting paraffin wax from crude oil. He established a company called Young’s Paraffin Light and Mineral Oil Company, which became one of the world’s largest producers of paraffin wax.
Candle-Making Revolution
Candles were primarily made from tallow (animal fat) or beeswax, which were expensive and had limitations. Paraffin wax provided an inexpensive and readily available alternative, and it could be quickly melted, moulded, and solidified, resulting in a more affordable and consistent light source.
Expansion of Applications
In the late 19th century, paraffin wax found use in various industries. It was utilised as a waterproofing agent for textiles and as a component in manufacturing matches, sealing wax, and lubricants. Paraffin wax coatings were also applied to paper and cardboard to improve their resistance to moisture and grease.
Development of the Petroleum Industry
The widespread use of paraffin wax played a significant role in developing the petroleum industry. As the demand for paraffin wax grew, it provided a market for petroleum by-products, encouraging further exploration and crude oil extraction.
Advancements in Production Techniques
Over time, advancements in refining and purification processes improved the quality and purity of paraffin wax. New techniques, such as solvent dewaxing and hydrotreating, were developed to remove impurities and optimise the properties of the wax for specific applications.
Alternatives and Environmental Concerns
Alternative waxes such as soy wax and beeswax have become famous due to environmental and sustainability concerns. These waxes are considered more natural and renewable compared to petroleum-based paraffin wax. The demand for eco-friendly and biodegradable alternatives has led to the exploration of new wax options.
Despite the emergence of alternatives, paraffin wax remains largely used due to its favourable properties, versatility, and cost-effectiveness. Its history marks a significant milestone in the utilisation of petroleum by-products and the development of various industries.
