The difference between solid paraffin and liquid paraffin

Fushun paraffin, also known as crystallized WAX, is a lamELLAe paste obtained by distillation of crude oil through solvent purification, solvent dewaxing or freeze crystallization of wax, pressure dewaxing to obtain wax paste, and then solvent deoiling and refining. Needle-like crystals are mixtures of hydrocarbons with a carbon number of about 18 to 30. The main components are straight-chain alkanes. Liquid paraffin is a colorless, odorless mixture obtained from fractionation of crude oil. The main component is C16-C20 normal paraffin. .

Different structure: solid paraffin wax is a mineral wax, the main composition is C18-C30 linear paraffin, also contains heterocalkanes, cycloalkanes and a small amount of aromatic hydrocarbons. Liquid paraffin is a petroleum product composed of saturated components of petroleum hydrocarbons and cycloalkanes.

Different uses: Solid paraffin can be used to make rubber products, wax paper, crayons, food and pharmaceutical ingredients; Liquid paraffin is used as a lubricant plasticizer in the plastics industry, as a fiber oil agent in the textile industry, and as a lubricant in tool machines. Preservatives. It is also used as an additive in the cosmetics and food industries.

Different appearance: liquid paraffin is colorless, transparent, tasteless, non-fluorescent liquid oil; Solid paraffin is a tasteless, tasteless white solid (yellow when containing impurities).

Liquid paraffin (a mixture of liquid hydrocarbons) : USED mainly to adjust the consistency of ointments, but also in the oil phase of emulsion substrates. (Liquid stones used in oily or water-in-oil emulsions are used to disperse drugs. That is, when the drug powder is dispersed directly into an oily or water-in-oil matrix, it does not mix well. It is ground into liquid paraffin to disperse evenly and then mixed with an oil-based matrix.

Solid paraffin wax is a mineral wax, which is a solid hydrocarbon obtained by cold pressing or solvent dewaxing a light lubricating oil fraction by sweating or solvent deoiling. The main composition is C18-C30 straight chain alkanes, which also contains isochain alkanes, cycloalkanes and a small number of aromatic hydrocarbons. It can be used to make rubber products, wax paper crayons food and pharmaceutical ingredients.
