Peroxide, stable

Dycho White THD (Blue). [Dycho] Peroxide stable brightener for cellulo-sics. 

BETRAPRONE (57-57-8) Combustible liquid (flash point 165°F/74°C). Able to polymerize in elevated temperatures and decomposes at room temperature, forming unstable peroxides stable below 41°F/5°C. Violent reaction with strong oxidizers, strong acids, alkalis, aniline, chlorosulfonic acid, 1,2-ethanediamine, ethanolamine, ethyleneimine, pyridine, sodium hydroxide. Incompatible with 2-aminoethyl alcohol, ammonium hydroxide. Hydrolyzes in fresh water, forming hydracrylic acid in salt water reacts with the chloride, forming 3-chloropropionic acid. 

New kinetic regularities at polymerization of vinyl monomers in homophase and heterophase conditions in the presence of additives of transition metal salts, azonitriles, peroxides, stable nitroxyl radicals and radical anions (and their complexes), aromatic amines and their derivatives, emulsifiers and solvents of various nature were revealed. The mechanisms of the studied processes have been estabhshed in the whole and as elementary stages, their basic kinetic characteristics have been determined. Equations to describe the behavior of the studied chemical systems in polymerization reactions proceeding in various physicochemical conditions have been derived. Scientific principles of regulating polymer synthesis processes have been elaborated, which allows optimization of some industrial technologies and solving most important problems of environment protection. 

New kinetic regularities have been revealed at polymerization of viityl monomers in homophasic and heterophasic conditions in the presence of additives of transition metal salts, azo nitriles, peroxides, stable nitroxyl radicals and anion radicals (and their complexes), aromatic amines and their derivatives, emulsifiers and solvents of varions nature.
