Perchlorates are powerful oxidizing substances. These compounds explode when mixed with combustible, organic, or other easily oxidizable compounds and subjected to heat or friction. Perchlorates explode violently at ambient temperatures when mixed with mineral acids, finely divided metals, phosphorus, trimethylphosphite, ammonia, or ethylenediamine. Explosions may occur when perchlorates are mixed with sulfur, or hydride of calcium, strontium, or barium and are subjected to impact or ground in a mortar. Perchlorates react with fluorine to form fluorine perchlorate, an unstable gas that explodes spontaneously. Heating perchlorates to about 200°C (392°F) with charcoal or hydrocarbons can produce violent explosions. Metal perchlorates from complexes with many organic solvents, which include benzene, toluene, xylenes, aniline, diozane, pyridine, and acetonitrile. These complexes are unstable and explode when dry. Many metal perchlorates explode spontaneously when recrystaUized from ethanol. Saturated solution of lead perchlorate in mathanol is shock sensitive. 

The interaction process between aqueous solutions of potassium stearate with calcium chloride, in tubular turbulent devices, provides a stoichiometric reaction leading to a reduction of the reaction mixture residence time in the device, which prevents particle deposition on the technological equipment walls, and consequently increases the run between repairs reduces the specific amount of metal per structure due to the small size of the reactor reduces the process power capacity due to the removal of the mechanical mixing devices from the flow sheet and produces a finely divided suspension of the adhesion reducing powder.
