History of paraffin wax

Paraffin wax was first produced commercially in 1867

less than 10 years after the first petroleum well was drilled. Paraffin waxcolorless or white, somewhat transparent, wax consisting of a mixture of solid straight-chain hydrocarbons ranging in melting point from 58° to 68° C. Paraffin wax is derived from petroleum by de waxing light lubricating oil stocks. It is used in candles, wax paper, polishes, cosmetics, and electrical insulators. It assists in extracting perfumes from flowers, forms a base for medical ointments, and supplies a waterproof coating for wood. In wood and paper matches, it helps to ignite the matchstick by supplying an easily vaporized hydrocarbon fuel.

Paraffin wax precipitates readily from petroleum on chilling. Technical progress has served only to make the separations and filtration more efficient and economical. Purification methods consist of chemical treatment, de colorization by adsorbents, and fractionation of the separated waxes into grades by distillation, recrystallization, or both. Crude oils differ widely in wax content.

Snow-white and harder than petroleum paraffin wax

the synthetic product has a unique character and high purity that make it a suitable replacement for certain vegetable waxes and as a modifier for petroleum waxes and for some plastics, such as polyethylene. Synthetic paraffin waxes may be oxidized to yield yellow, hard waxes of high molecular weight., such as borax, sodium hydroxide, triet4hanolamine, and morphine. These wax dispersions serve as heavy-duty floor wax, as waterproofing for textiles and paper, as tanning agents for leather, as metal-drawing lubricants, as rust preventives, and for masonry and concrete treatment.
