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 CP-470 (paraffin chlorinated liquid) is a transparent oily liquid from yellow to slightly brown in color without mechanical impurities. Light opalescence is permissible. KhP-470 A / B is highly soluble in mineral and lubricating oils, chloroorganic solvents, ethers, ketones, etc., is limitedly soluble in alcohols, combined with rubbers, polyester and various alkyd resins.

HP-470 is used in the following industries and technologies:

  •  Used in the production of rubber, plastisols and PVC pastes, as a plasticizer of emulsion resin;
  •  as a liquid filler to reduce the cost of the product.
  •  secondary plasticizers of PVC compositions, polyvinyl chloride, in the production of cable plastic compounds.
  •  in the production of roofing materials (for the production of soft tiles);
  •  production of nitrocellulose varnishes for wood processing. In the production of the following inks: ED enamel, acrylic paints, alkyd paints, road paints, auto enamels, silicate enamels.

Properties

Chloroparaffin CP-470 - difficult to fire, fire and explosion-proof, low-toxic, non-volatile substance, does not have harmful effects on the human body. Refers to the III toxicological hazard class. But, when working with Chloroparaffin HP-470, protect the skin and mucous membranes of the eyes with the help of personal protective equipment. During processing at a temperature above 200 ° C, hydrogen chloride can be released. Chloraparaffin is poured into cans or barrels, transported in covered vehicles by road and rail in accordance with the rules of transport operating on this mode of transport. Keep chloroparaffin HP-470 in closed containers in unheated rooms. fireproof and explosion-proof, low-toxic, non-volatile substance, does not have harmful effects on the human body. Guaranteed shelf life: brand A - 12 months, grade B - 3 months.

The density is 1.235 g / cm3. Freezing point, 0 ° C degrees. It is well soluble in mineral and lubricating oils, chloroorganic solvents, ethers, ketones, etc., is limitedly soluble in alcohols, combined with rubbers, polyester and various alkyd resins.
During the processing of chloroparaffin CP-470, at a temperature of more than 200 ° С, hydrogen chloride can be released.

 

Application

  • Chloroparaffin HP-470 is used in the following industries and technologies:
  • in the production of plastisols and PVC pastes, as a plasticizer of emulsion resin;
  • as a liquid filler to reduce the cost of the product;
  • as a secondary plasticizer in various light polymer compositions (cable, shoe and other plastics, linoleum, films, etc.);
  • in the production of roofing materials (for the production of soft tiles);
  • in the production of nitrocellulose varnishes for woodworking;
  • in the production of paints: ED enamel, acrylic paints, alkyd paints, road paints, auto enamels, silicate enamels;

It is easily combined with the main 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, fitting) products.

 

Safety requirements

Chloraparaffin HP-470 is a low-toxic, hard-burning, third-hazard substance. Working with it, you need to use rubber gloves and goggles to protect the skin and mucous membranes of the eyes. Store chloroparaffin ХП-470 in a dry, cool room, in tightly closed containers or barrels of steel, without the possibility of moisture, heat and direct sunlight.
