Chemical properties 
White to light red crystalline powder. Melting point 69.5 degrees C, boiling point 272.5 degrees C. Soluble in ethanol, ether, benzene, chloroform and petroleum ether, 1 serving is soluble in about 200 parts of water.
Production method
It is obtained by the reaction of radon and iron trichloride. 70g waterless molybrow was mixed with 13g waterless iron trichloride and heated in a pipe at 300c for a reaction of about 35h. After cooling, the reactant solidifies to red-black crystallization, opens the seal pipe, and washes out the red-black solution of the solids with a small amount of hot water. Remove oily impures with ether extraction. After neutralising sodium bicarbonate, steam heating removes excess radon. The mixture is then turned into a strong alkaline and steamed out of 2,2'-co-cocoons. After the vaporization acidization evaporates and concentrates, then adds sodium hydroxide, extracts with ether, removes the coarse ether. Crude products with B to recrystallize, activated carbon decolorization is pure. In addition, the product can also be produced by the reaction of α-methylquine with potassium permanganate
