The industrial name: chlorinated paraffin CPW 50/52

The appearance form: clear yellowish viscous liquid with a distinct sweet smell

Paraffin is a generic name for alkanes with the chemical formula C n H2 n + 2 . Paraffin wax refers to solid paraffin with n = 20-40. Paraffin is a petroleum material found in the market in either liquid or solid or jelly form, the type of jelly and solid used for the production of candle types and the liquid type for industrial use.

Paraffin oil was invented in the 19th century by a German scientist named Carl von Reichenbach. This was when he was trying to increase the efficiency and refining of the oil compounds in the petrochemical industry. It was used because paraffin was a much cleaner and more reliable fuel than conventional oils in the candle making industry. The discovery of paraffin gave a new boom to candle manufacturing, meat packaging, and the oil industry in the early 20th century.


Paraffin types

Paraffin wax is divided into three general categories of Edible, Industrial and Sanitary.

Industrial Paraffin: It has flashpoints of 120 - 140 - 160 - 180 and 200 and is used in textile and textile industries as well as lubricants for food machinery.

Health Paraffin: Most used in cosmetics, such as the production of hand and face creams, emollients, cosmetics, and wipes.

Edible paraffin: It is refined and free of toxic and harmful substances. It is divided into two categories of human food that are used for the production of human food and animal feed paraffin in dairy farms to relieve stomach and sheep bloating.

Chlorine paraffin 52% is a clear viscous liquid with a sweet smell. Chlorine paraffin is a valuable material that is classified in terms of chemical classification as plasticizers and considered as an industrial paraffin. It is not soluble in water, but soluble in other solvents. Chlorine paraffin (CPs) is a chlorinated chain hydrocarbon and are classified by carbon chain length and percentage of chlorine. The overall length of the carbon chain is generally from 10 C to 30 C and chlorination of approximately 35% Up to 70% by weight. The three most common commercially-available paraffin with carbonate numbers are short chains (C 10-13), medium chains (C 14-17) and long chains (C 18-30).


They are used in the polymer industry, especially in PVC, as Plasticize Softener, to delay Flame-retardant flammability for plastics and tires, as a depressant Point Pour in paints, as well as in paints. The additive for high-pressure engine oil is widely used and hundreds of thousands of tons of this substance are produced and consumed worldwide each year. In the country, paraffin chloride 52% has been widely used as a softener in the cabling, synthetic leather, flooring, etc., as a single use grade alone or alongside DOP.

The chemical and physical properties of chlorine paraffin depend on the following factors:

1 - The length of the hydrocarbon chain

2 - chlorine content of the product

3. Reaction conditions (especially reaction temperature)

Physical Properties

Chlorine paraffin is physically a homogeneous substance. This compound is colorless or colorless yellow, amber or honey yellow. The most important properties of chlorine paraffin is viscosity, density, thermal stability, solubility and refractive index. Most chlorine paraffin becomes darker with heat as a result of the release of HCl.

chemical properties

Chlorine paraffin is not a simple chemical compound, but rather a complex mixture of various molecules whose differences are along the hydrocarbon chains, the number and location of chlorine atoms attached to these chains. In products with low chlorine percentages, chlorinated paraffin molecules During the chlorination process of paraffin, type III carbon atoms react more rapidly than type II; and type II carbon atoms reacts faster than type I, but the stability of the working atoms in paraffin is the opposite of the rule and is reduced from the type I to the third. Chlorine paraffin decomposes by light or heat above 120 degrees Celsius, and the decomposition process is carried out by removing hydrogen chloride gas. This is called a dehydrolysis reaction.

The industrial paraffin manufacturing process

A - Acidic process: In this method “Slack wax”, the gross paraffin separation is done after re-melting and cooling by Centrifugation in acid-free solvent. Afterwards, the product gets dried and is purified with sulfuric acid. A final filtration is carried out to remove impurities by using soil, and after filtration the wax is obtained and it gets finally packed.


B - Sweating process: In this method “Slack wax”, after initial molding and oil sintering and acid purification by sulfuric acid, subsequently, the same treatment as per the acidic process (from the purification stage onwards) Continues.



It should be stored in steel warehouses with compressed air or in drums which are stored in cool warehouses. Guaranteed life is one year from the date of production.
