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.

 

Description

Chloroparaffin HP-52 is made from paraffin, contained in crude oil. There are liquid chloroparaffins (with a mass fraction of chlorine of 50%) and solid paraffins (the mass fraction of chlorine is 70-72%). The properties of this material determine its significant popularity and application in the chemical industry.

• Due to the property of dissolving in most known organic solvents, paraffin is well combined with various film-forming agents. Due to this, it is often used as resins and plasticizers.
• Chlorinated paraffin ХП-470 has found its application in the pharmaceutical industry due to its physical properties.
• It is also used to increase the fire resistance of building materials, fabrics and paper, which significantly reduces their gross value.
• Chlorinated paraffin is also an excellent additive necessary to improve the lubrication of oils. Used in lubricating-cooling oils designed for metal cutting operations.
• It is necessary for the production of plastisols and PVC pastes, nitrocellulose varnishes intended for wood processing. Used in the creation of paint and varnish materials and building sealants.
• Often used as a plasticizer of emulsion resins. Also acts as a secondary plasticizer in PVC compositions.

 

Application

As a secondary plasticizer in polymer compositions (cable, shoe, etc. plastic, films, plastisols, linoleum, etc.), a component in the fat compositions in the leather industry.
It is well combined with the basic plasticizers based on phthalic acid (DBP and DOP) and is easily introduced into the composition of PVC compositions used for the production of soft (cable, hose, boots, films, linoleum, etc.) and "hard" (pipe, fittings) of products.

 

Safety requirements

Difficultfire, fire and explosion-proof substance, low toxicity. Does not have harmful effects on the human body. Refers to the 4th class of danger. When working with chloroparaffin ХП-470 protect the skin and mucous membranes of the eyes with the help of individual protective equipment. At a temperature below 0 ° C, the product freezes, and therefore it needs to be heated before the filling.
