For synthesis of terephthalic acid from Phthalic anhydride by the Henkel process in industrial scale, studies have been made on its reaction vessel and recovering of potassium. The result was able to clarify on its reaction mechanism. The reaction vessel for a continuous reaction as a thin film on a steel belt was simple in operation and good result was obtained. For recovering of potassium, a direct one or two step exchange of Phthalic acid and potassium terephalate, sulfurous acid gas method and carbon dioxide method were tested. The resut indicated that sulfurous acid gas-calcium hydroxide method and neutralization-sulbimation separation method of using two moles Phthalic anhydride, concentration of monopotassium phthalate, and heating of the solid phase above 300°c for separation of dipotassium phthalate and Phthalic anhydride for their separation by sublimation gave good result. Studies on the reaction products indicated that the end product of reaction around 360°c was terephthalic acid, a small amount of Phthalic anhydride and large amount of benzoic acid. Further continuance of the reaction indicated the formation of benzoic acid dianion as an intermediate product from the fact that there was little or no formation of benzoic acid and from the consideration of melting point of potassium benzoate, potassium phthalate and potassium terephthalate. Metal (Cd, Pb, and Zn) carbonates as effective catalyst showed far lower decomposition temperature for conversion into oxide and liberation of carbon dioxide than other metal carbonates. Therefore, those which showed catalytic activity were considered to have an ability of holding decarboxylated carbon dioxide without losing it out of the system.

Vapor phase condensation by dehydration of paraldehyde and formaldehyde (molar ratio 1: 3) through Li3CO3-silica gel catalyst for formation of acrolein has been investigated with reaction temperature range of 300-450°c and space velocity (SV) (of formaldehyde) at 3-24 mM/hr./g, catalyst. The result indicated that the maximum yield (to the feed passed) of 52-53% was obtainable with SV=6 mM/hr./g, catalyst and reaction temperature at 350°c. The side reaction product showed a considerable decrease with an increase of SV, there was practically no formation in 2.5 hrs, after the reaction at 12 mM/hr./g, catalyst (reaction temperature range at 360-400°c), and the yield under this condition was 44.6%.

Syntheses of Bistriazinylaminostilbene derivatives and examination of their properties in the first report indicated that there were several kinds of compound having value for industrial application. A few of the compounds among these products were tested fo estimation of ultraviolet absorption spectra, dyeing experiments, and fundamental conditions for their syntheses. Several kinds of product having value for practical use were tested for dyeing property of cotton and fastness. The product having value for practical application on Nylon was used for comparison with a commercial fluorescent dye (a coumarin derivative) for Nylon on dyeing ability and fastness.

The applications of ethyleneimine derivatives to dyestuffs were investigated, and useful reactive dyestuffs were synthesized. Introducing aziridinyl groups into dyestuff molecules makes generally the dyestuff insoluble in water. In dyeing, textile fabrics are padded in the dyestuff suspension and then heat-treated. The fastness of the dyestuff is appreciably improved and the color is not changed. Copper phthalocyanine dye was chlorosulfonated and then reacted with ethyleneimine to give di- and tetra-substituted compounds. The tetra-aziridinyl compound is insoluble in water.The di-aziridinyl compound, however, was made soluble in water by changing the remaining two sulf ochloride groups into sodium sulf ovate groups. The dyestuff thus modified has partially the properties of acid dye, and can uniformly dye not only cotton but wool, nylon and polyacry lonitrile fabrics in the usual method of dyeing. The color of the dye was very bright blue and the fastness was the highest.

Addition of a small amount of peroxybenzoic acid to methyl methacrylate and acrylonitrile initiated their polymerization, in the absence of oxygen and the reaction was proceeded up to the formation of product having high degree of polymerization. This polymerization was inhibited well by the presence of a small amount of radical polymerization inhibitor. This fact suggested that peroxybenzoic acid is effective for initiating of radical polymerization and its further confirmation was made by copolymerization of styrene and methyl methacrylate, and acrylonitrile and methyl methacrylate, respectively, and their reactivity ratio was estimated. The fomer gave larger error in the estimated value as the progress of copolymerization was slow, but the latter gave an accurate value. Each of them showed the rate of radical polymerization as reported in the past literatures. This fact was clarified that peroxybenzoic acid in acrylonitrile and methyl methacrylate is effective in initiating the polymerization by radical reaction.
