ジャーナル フリーThe vapor phase catalytic reaction of 1, 1, 2, 2-tetrachloroethane (1) and chlorine for a direct synthesis of perchloroethylene (2) has been investigated. Also, expectable reactions of vapor phase catalytic dehydrochlorination reaction of (1) and pentachloroethane (3), and vapor phase catalytic chlorination of trichloroethylene (4) during the process of above reaction have been investigated. Discussion on the mechanism of this reaction as well as the consideration were made on the relation between the surface area of catalyst and the activity of catalyst.
Activated carbon showed strong catalytic activity for both of dehydrochlorination and chlorine additive reactions. The dehydrochlorinating activity of activated carbon showed considerable differences by the kinds of activated carbon. In the preparation of activated carbon from the same raw material, the higher the steam activation temperature the larger was the surface area within our experimental range; it was also accompanied with higher dehydrochlorinating activity and higher stability in activity. However, there was no great change in chlorine addition activity by the difference in kinds of activated carbon.
The catalytic reaction over activated carbon was proceeded in the direction of (1)→(4)→(3)→(2) in the same way as in the case of thermal chlorination The optimum temperature for formation of (2) was 400-425°C and there was no side reaction to give other than C2-compound.
Addition of 10% BaCl2 or KCl to the activated carbon gave no great change in catalytic activity but au addition of 10% CuCl2, FeCl3, ZnCl2, or HgCl2 caused lowering of dehydrochlorinating activity and accompanied with renewed strong substituted chlorinating activity.抄録全体を表示PDF形式でダウンロード (1392K) -

ジャーナル フリーThe data of partial rate factors for the homolytic arylations of mono-substituted benzenes at 20.0°C are summarised. It will be noted that for each arylation, the logarithm of the partial rate factors of the meta positions of the aromatic compounds C6H5X are nearly linearly related to the values of Hammett's substituent-constants of m-X. Least squares treatment leads to a value for the reaction-constant of -0.81 for the p-nitrophenylation, -0.27 for the p-chlorophenylation, +0.07 for the phenylation, +0.03 for the p-tolylation, and +0.09 for the p-methoxyphenylation. These values concord with the polar natures of the aryl radicals.抄録全体を表示PDF形式でダウンロード (843K) -

ジャーナル フリーReactions of ethleneimine with various aldehydes and acid chlorides were investigated. The reaction products retain the reactive aziridinyl groups in their molecules, and can react with cellulose.
Diaziridinyl phenyl methane obtained by the reaction of ethyleneimine with benzaldehyde and N-stearoyl ethyleneimine obtained by the reaction of ethyleneimine with stearoyl chloride were investigated to use as the finishing agents of viscose rayon fibers.
It was found that the physical properties of the fibers treated with these agents in solution are hardly affected by the treatments, but the dyeability is considerably improved. The fibers are dyeable almost alike wool.
It is considered that only the surface of the fibers are modified chemically in the treatment with the finishing agents.
Viscose rayon fibers which are mixed-spun with small amounts of diaziridinyl, phenyl methane were produced, but the physical properties of the rayon fibers were not found to be so good.
Compounds produced by the reactions of ethyleneimine with furfural, glyoxal and glutaryl dialdehyde were so unstable that they could not be used in the finishing of the cellulose fibers.抄録全体を表示PDF形式でダウンロード (664K) -

ジャーナル フリーReactions of ethyleneimine with adipyl chloride and cyanuric chloride were investigated. And the reaction products were examined to use as the finislling agents of textne fabrics.
The treating of cotton fibers with adipino bis-ethyleneimie was found to improve the dyeability of the fibers without changing other properties.
Tris-(1-aziridinyl)-s-triazine has the feature of imparting some water resistance to cotton and woolen fabrics. When cotton fabrics were beforehand with adsorbing pigment colors by being dipped in the suspension and treated with tris-(1-aziridinyl)-s-triazine, the fabrics were firmly dyed with the pigment colors.
Introduction of aziridinyl group to the cyanuryl group of the reactive dyestuffs of procion type did not change the dyeability to cellulose fibers but improved the dyeability to wool fibers.抄録全体を表示PDF形式でダウンロード (772K) -

ジャーナル フリーSyntheses and properties of bistriazinylaminostilbene derivatives have been investigated in order to select excellent fluorescent dyes for practical use. In the synthesic experiment, change of combinations of substitution groups on the triazine ring has been made and the derivatives thus obtained were tested on their solubility, acid-resistant, property of aqueous solution and increasing of whiteness of cotton and Nylon. The result indicated that the product having a strong property of increasing of whiteness was found to be limited on a compound of one molecular condensate of sodium 4, 4′-diaminostilbene-2, 2′-disulfonate having one of each of aromatic amine residual group as a substituent group on two triazine rings.
Among the derivatives of this type of compound prepared, there was a compound having value for practical use in increasing the whiteness of Nylon.抄録全体を表示PDF形式でダウンロード (1671K) -

ジャーナル フリーHydrolysis of α, α, α, ω-tetrachloroalkane by sulfuric acid was found to be suitably made with the concentration of 90-96% from the estimation of the rate of reaction.
Since the addition of 60% sulfuric acid from using of 98% sulfuric acid and water to the reaction system was effective in lowering the temperature of reaction, it was useful for preventing formation of resinous substance from the reaction mixture and securing of highly pure ω-chlorocarboxylic acid was possible. However, using of 98% sulfuric acid more than that of necessary amount accelerate the formation of tar and decreased the yield. The reactivity was in the order of 1, 1, 1, 5-tetrachloropentane>1, 1, 1, 7-tetrachloroneptane>1, 1, 1, 9-tetrachlorononane>1, 1, 1, 3-tetrachloropropane.
The hydrolysis of tetrachloroalkane from propylene resulted in a violent resinifying reaction and dehydrochlorination by sodium sulfide gave better result.抄録全体を表示PDF形式でダウンロード (911K) -
