    The attempted synthesis of 1, 9-nonamethylenediamine using thiophene as a raw material was investigated. Namely, bis(5-nitro-2-thienyl) methane and his (5-chloro-2-thienyl)methane having 9 carbon atoms were synthesized from thiophene through his (2-thienyl)methane and it was tried to obtain a straight chained compound having 9 methylenic carbon atoms by various methods of reductive desulfurization of these two compounds but these tests were unsuccessful. Under similar reductive conditions, reductive desulf urization of his (2-thienyl) methane did not occur, but it of his (5-acetyl-2-thienyl) methane was very easy and gave a straight chain compound of 1, 9-diacetyl nonane.

    Reaction of 2, 4-dichloro-6-isocyanato-s-triazine with amines, such as methylamine, dimethylamine, ethylamine, diethylamine, isopropylamine, n-butylamine, piperidine, morpholine, aniline and diphenylamine gave N-(2, 4-dichloro-s-triazinyl)-N1-alkyl (or phenyl) ureas, and the same reaction with alcohols, such as methanol, ethanol, n-propanol, n-butanol and benzyl alcohol gave derivatives of carbamic acid. Then the conditions for their syntheses and the properties of their products are given.

    Vapor phase catalytic reaction of benzaldehyde and ammonia was investigated . It was found that activated carbon, vanadium oxide and molybdenum oxide, as well as silica gel and activated alumina gel, showed the activity for formation of benzonitrile. From the experimental results of using alkali-treated alumina catalyst, the activity of catalyst for formation of benzonitrile did not depend on the acidic point for alkali poisoning but on another kind of active site . Solid acids or those having the behaviors of the solid acid showed a general tendency of forming toluene and benzene as the by-products . These facts were considered to have relation with the acidic point for alkali poisoning . It was confirmed that the formation of toluene was due to the disproportionation reaction of the benzyl alcohol which was formed by disproportionation reaction of benzaldehyde in the presence of solid acid and water (formed in formation of benzonitrile) . It was considered that benzene was formed from decarbonylation of benzaldehyde .

    A method of preparation of alumina catalyst suitable for the synthesis of acetonitrile from acetylene and ammonia in fluidized bed and the activity of the catalyst was investigated. A quartz reaction tube of the diameter 1.5 inch was used and the grain size of the catalyst was 100-200 mesh. Under a definite fluidized synthetic condition, nearly equal catalytic activity was obtained in spite of the differences in the method of preparation of alumina, and when the catalyst prepared by addition of 3-4 wt% of Na2CO3 according to Murakami, Shiba etc, was used, the side reaction such as formation of pyridine base and hydrogen cyanide and another decomposition reaction was prevented, the selectivity for acetonitrile being increased. The activity of two kinds of alumina catalyst prepared by addition of alkali before or after calcining of aluminum hydroxide became nearly equal after repetition of reaction. This can explaine well that the effective site of activity for synthesis of acetonitrile is on the outer surfaceof the catalyst. The regeneration of catalyst prepared by addition of optimum amount of sodium carbonate is made easily by treatment with air at the same temperature range as at the synthesis.

    The preceeding report dealt with the investigation on the conditions for preparation of alumina catalyst to be used for synthesis of acetonitrile in fluidized bed, while this report deals with the investigations on the effect of water vapor, the change of activity of catalyst with the life time and the effect of grain size of catalyst treated with optimum amount of alkali. A quartz reaction tube of the diameter 1.5 inch and the grain size about 100-200 mesh of catalyst were used. There was an optimum partial pressure of water vapor for this reaction and the formation of ammonium carbamate was accelerated by the presence of excess of water vapor. Using alumina catalyst for a long time of reaction gave a sudden decrease of activity of the catalyst after a certain time. It is considered this is due to the poisoning of main reaction activity by the side reaction product formed at different acidic point other than the activity point for synthesis of nitrite. As the fluidization of powder in the fluidized bed becomes more easy by the presence of particles of small size, the presence of such small particles has much effect on the result of reaction.
