Abstract: Provided are a granular inorganic filler which is highly effective in improving the physical properties of resins and excellent in working efficiency, working atmosphere, productivity and economical efficiency, a process for producing the filler, and resin compositions excellent in mechanical properties, surface appearance, flame retardance and antiblock properties. The filler is produced by granulating a mixture comprising inorganic filler particles having a mean particle diameter of 0.01 to 20 &mgr;m and a binder in such a way as to give an apparent density of 0.1 to 3.0 g/ml and a breakage rate of 5 to 80 wt %. The resin compositions are prepared by adding the granular inorganic filler to resins.

Abstract: A process for producing a 3-chloro-5-trifluoromethylpyridine derivative comprises reacting a 5-trifluoromethylpyridine derivative having a hydrogen atom at 3-position with chlorine. The process is characterized by reacting said 5-trifluoromethylpyridine derivative with chlorine in a vapor phase in the presence of a catalyst selected from the group consisting of activated carbon and a chloride of a metal element selected from the group consisting of iron, antimony, copper and zinc.

Abstract: An aminobenzene is produced by reacting a chlorobenzene with ammonia in the presence of a copper type catalyst, namely by reacting ammonia with 3,5-diaminochlorobenzene to produce 1,3,5-triaminobenzene at a temperature of 150.degree. to 250.degree. C. at a molar ratio of ammonia of 2 to 10 to 3,5-diaminochlorobenzene in the presence of a copper compound catalyst.

Abstract: 1,3,5,-Trichlorobenzene is produced by chlorinating 1,3,5-trihalobenzene having 1 to 3 bromine atom and 2 to 0 chlorine atom. The gaseous 1,3,5-halobenzene having 1 to 3 bromine atom and 2 to 0 chlorine atom is brought into contact with chlorine gas at a molar ratio of 0.5 to 3.0 of the stoichiometric amount of chlorine required for said conversion, in a vapor phase at a temperature of 280.degree. to 500.degree.
