Another group of chlorinated hydrocarbons comprises those made from paraffin wax. Major applications are in extreme pressure lubricants and as extenders and plasticizers in surface coatings and in vinyl plastics. The chlorinated waxes were also widely applied in flameproofing cotton fabrics, which led to large consumption by the military. It is believed that current military requirements for flame-resistant fabrics will be met by vinyl sheeting of vinyl-coated textile products, so that the World War II demand for the halogenated waxes will not be repeated.

HALOGENATED WAXES (1336-36-3) see PCBs or polychlorinated biphenyls. HALOWAX 1014 (1335-87-1) C,oH,CI Combustible solid (flash point unknown). Violent reaction with strong oxidizers, strong acids, powdered aluminum, potassium, sodium. On small fires, use dry chemical powder (such as Purple-K-Powder), alcohol-resistant foam, water spray, or COj extinguishers. Thermal decomposition releases toxic hydrogen chloride and phosgene gases. 

Polychloiinated naphthalenes (PCNs) are halogenated aiomatic hydiocaibons that are no longer produced. They can be synthesized by the chlorination of naphthalene. The commercial products were graded and sold according to their chlorine content (wt %), and used as waxes and impregnants (for...

Firedamp-proof Detonators. Firedamp-proof detonators have net received tht attention that firedamp-proof expls have, possibly because the expln of the, detonator is lost in the immediately succeeding expln of the main charge. Treatment of the detonator charge in caps follows similar lines to treatment of Dynamites in the addition of cooling additives, such as salts or wax (Ref 1), BuOAc (butyl acetate) (Ref 2), or poly car boxy lie acids, oxygenated poly carboxylic acids, halogen substituted poly carboxylic and oxygenated polycarboxylic acids, and the neutral and acid salts of these (Ref 4)... 

Both types of wax are readily oxidized (24) and halogenated (116). The latter is an important commercial outlet, the products of which are used as extreme pressure additives for oil (112,113) and as intermediates in Friedel-Crafts condensations (119). Air oxidation leads to carboxylic acids, for which considerable use has been found both here and abroad. Sulfonates can be made by reaction of waxes with chlorosulfonic acid (37,104) or with sulfur dioxide and chlorine (46,99).

Fat- and oil-soluble dyes are also soluble in waxes, resins, lacquers, hydrocarbons, halogenated hydrocarbons, ethers, and alcohols, but not in water. It is not possible to differentiate clearly between them and the alcohol- and ester-soluble dyes. With the exception of blue anthraquinone derivatives, fat- and oil-soluble dyes are azo dyes, generally based on simple components. According to their degree of solubility they usually contain hydroxyl and/or amino groups, but not sulfonic acid and carboxylic acid groups. Examples of fat- and oil-soluble azo dyes are C.I.

CHLOREZ is compatible with most commonly used resins, rubbers, plasticizers, waxes, and drying oils. Because of their very high active halogen content and low cost, CHLOREZ products are finding wide usage as flame retardant additives in coatings, inks, plastics, foams, adhesives, paper and fabrics. 

Polymer films can also be deposited on solid particles by vapor phase reaction or from a melt. The best example of vapor phase reaction is the deposition of Union Carbide s Parylene , a derivative of p-xylylene. In this process, di-p-xylylene, or more commonly a halogenated derivative of it, is vaporized in a vac and therm-mally dissociated into the very reactive monomer, a diradical. The monomer is allowed to condense on the surface of the particles to be coated, where it instantaneously polymerizes to form a high molecular weight, polymeric film (Ref 10). Less reactive, vaporizable or meltable polymers can be applied by hot spraying onto agitated particulates or by deposition in a fluidized bed or in liq suspension (Ref 2). Wax is a common example of wall material applied in all three ways...
