Chlorinated paraffins. General information

Chloro paraffins - not soluble in water; liquid chloroparaffins are highly soluble in mineral and lubricating oils, chlorine solvents, ethers, ketones, etc., are limitedly soluble in alcohols, combined with rubbers, polyester and various alkyd resins; solid chloroparaffin are boundedly soluble in acetone and benzene. At temperatures above 150 ° C or when boiling with alcohol solutions of alkali chloroparaffins dehydrochlorinated to form higher chloro-olefins. In the presence of water, they hydrolyze.

Liquid chloroparaffins are prepared by periodic chlorination of molten paraffin at 90-120 ° C; after cooling to 60-70 ° C and blowing of dissolved C12 and HC1, a stabilizer, usually based on epoxy compounds, is added. The solid is obtained by chlorinating a 20% mixture of paraffin with CC14 at 70-75 ° C in the presence of a porophore initiator; after distillation of part CC14 in a 50% chloroparaffin solution, a stabilizer is added and the product is isolated by precipitation from water, or in a film evaporator.

Liquid chloroparaffins are used as plasticizers in polymer compositions of PVC, etc.), for the production of lubricants, for impregnating fabrics, paper, polymer films for the purpose of imparting fireproof and hydrophobic properties, for the production of chemically resistant, waterproof and flame retardant paints, etc. (Fire retardants) are used to increase the fire resistance of plastics, polystyrene, polyethylene, polyacrylates, etc.) and rubbers.

Chloroparaffins are difficult to burn, they are non-explosive and non-toxic.



It is readily soluble in chloroform and carbon tetrachloride, it is limitedly soluble in acetone, benzene. With an individual approach to the consumer, it is possible to change the characteristics with an increase in the melting point.



Chloraparaffin is used as an additive to polymeric materials (polystyrene, polyethylene, synthetic rubbers, plastics, etc.) and rubber compounds to reduce their combustibility (as a flame retardant) and enhance self-extinguishing properties, as well as in the manufacture of chemical-waterproof and fireproof paints based on perchlorovinyl resin, chlorinated rubber and other polymers. As a plasticizer for PVC.


Safety requirements

Low-toxic, difficult-to-fire, fire-explosion-proof substance that does not require special precautions. Eye contact may cause irritation. Skin contact does not cause irritation. Does not cause respiratory tract irritation under normal conditions
Refers to the 4th class of danger.
