| titleOfInvention | Method of producing heat stabilisers for chlorine-containing polymers |
| abstract | FIELD: chemistry. n SUBSTANCE: invention relates to an improved method of making heat stabilisers for chlorine-containing hydrocarbons, specifically to a method of obtaining stearates of bivalent metals used in polymer compositions based on chlorine-containing polymers such as polyvinyl chloride, vinylchloride copolymers, chlorinated polyvinylchloride etc. The method of producing heat stabilisers of chlorine-containing hydrocarbons involves reacting stearic acid and oxides or hydroxides of calcium, zinc, barium, magnesium or lead in form of separate of mixed salts of stearic acid in a solid phase with intense stirring. The process is carried out in the presence of sodium hydroxide or potassium hydroxide in amount of 0.05-0.15% of the mass of stearic acid and propylene carbonate or dimethylformamide, or hexamethapol or sulfolane or dimethylsulfoxide in amount of 0.005-0.05% of the mass of stearic acid at 40-95°C in a double-screw reactor. Catalysts of the process - sodium hydroxide or potassium hydroxide and propylene carbonate, or dimethylformamide, hexamethapol, sulfolane or dimethylsulfoxide facilitate considerable increase in activity of the surface of the substrate and, as a result, increase in the rate of the process and obtaining products in form of a homogeneous highly dispersed powder and prevention of secondary oligomerisation of the end product. n EFFECT: use of the invention enables design of a continuous highly efficient method of producing heat stabilisers of chlorine-containing polymers with high heat stabilising capacity due to formation of products in form a homogeneous highly dispersed powder. n 2 cl, 4 tbl, 15 ex |
