ジャーナル フリーThe acetates of neopentyl-type polyols, (R)n-C-(CH2OCOCH3)4-n(n=0, 1, 2), such as pentaerythritol tetraacetate, pentaglycerine triacetate, and neopentylglycol diacetate, undergo stepwise chlorination upon treatment with gaseous hydrogen chloride in the presence of zinc chloride. The fully chlorinated products, (R)n-C- (CH2Cl)4-n, however, can be obtained with difficulty. In order to clarify the mode of reactions, the acetates (0.334 mol) of various neopentyl-type polyols and some straight chain primary alcohols were treated at 160°C in the presence of zinc chloride catalyst (0.0081 mol) under the constant flow of gaseous hydrogen chloride, 500 ml/min, and the chlorination velocities measured. The results indicate that the ?A-substituent is the factor which affects the rate of reaction. When all the hydrogen atoms on the β-carbon of primary alcohol moieties are replaced by any substituent other than acetoxymethyl group, the chlorination velocity constant was ca . 10-5min-1. This value is far small when compared with that for the acetate of the unsubstituted alcohol (ca . 10-2min-1). However, when the substituents include at least one acetoxymethyl group, the value becomes to be in the order of 10-2min-1 .抄録全体を表示PDF形式でダウンロード (606K) -

ジャーナル フリー3, 3-Bischloromethyloxetane can be prepared in a good yield when pentaerythritol trichloroacetate is treated with sodium hydroxide in water. Small amounts of some by-products formed in such treatment were analyzed in order to clarify the mode of reactions. Pentaerythritol trichloroacetate, upon contact with sodium hydroxide in water, is first converted to pentaerythritol trichlorohydrin, which subsequently undergoes ring closure to form 3, 3-bischloromethyloxetane (1). During the course of this reaction, 2-chloromethyl-3-chloro-l-propene (2) is also formed through elimination of formaldehyde. 2, 6-Dioxaspiro [3, 3] heptane, 3-methyleneoxetane, 3, 3-bishydroxymethyloxetane and 3-chloromethyl-3-methoxymethyloxetane are identified as products formed from (1) through the 3-chloromethyl-3-hydroxymethyloxetane intermediate. In an analogous manner, (2) gives 2-hydroxymethyl-3-hydroxy-1-propene and 5-methylene-1, 3-dioxane.抄録全体を表示PDF形式でダウンロード (980K) -

ジャーナル フリーUnder ethylene pressure of 30 kg/cm2, radiation polymerization of ethylene was conducted in an autoclave using cyclohexane containing a small amount of carbon tetrachloride as a solvent. The reaction mixture was exposed to the γ ray from Cobalt-60 at a rate of 0.121 M rad/hr and total irradiation of 0.24-6.06 M rad at20°. Polymerization was found to proceed, in a stepwise manner, to form telomer, liquid products, and ultimately solid products. The reaction was accelerated in the presence of carbon tetrachloride, the mean molecular weight of the product being decreased at the same time. Like in the case of ethylene-carbon tetrachloride telomerization reaction, the products of this study probably contain four chlorine atoms per one polymeric molecule.抄録全体を表示PDF形式でダウンロード (734K) -

ジャーナル フリーLiquid as well as solid polymeric products are obtained by radiation polymerization of ethylene in cyclohexane containing carbon tetrachloride. The infrared absorption spectra indicate that the liquid product is structurally similar to the telomer and its -C-C- chain is rather extended. The solid product begins to show the properties of polyethylene as the polymerization reaction progresses. In this reaction, the telomer first formed probably grows into solid product through liquid intermediate. The solid product consists of three types of components of varying melting points. The component of relatively low melting point resembles with the liquid product, and it would probably change into the components with higher melting point as the reaction progresses. It is evident that some structural changes also take place as the molecular weight increases.抄録全体を表示PDF形式でダウンロード (830K) -

ジャーナル フリーA vapor mixture of benzene and air (1:1 in volume) was passed through a Pyrex-tube at 600°C, a residence time being 9 sec., and the product condensed was analyzed for phenol and biphenyl. Under those conditions, no appreciable amount of phenol was formed. In the presence of certain additives, however, phenol was obtained in a yield of 0.4-5% per pass. Such effective additives include cyclohexane, cyclohexene, dicyclopentadiene, and 2, 3-dimethylbutane. Bromine, iodine, sulfuryl chloride, most of the halogenated hydrocarbons, nitro- and nitroso-compounds were also found to be effective. On the other hand, n-hexane, toluene, and cumene were scarcely effective.抄録全体を表示PDF形式でダウンロード (1958K) -

ジャーナル フリー6-Chloroquinizarin was synthesized in good yield from 4-chlorophthalic anhydride and hydroquinone in the presence of sodium aluminum chloride. Disperse dyes of general formula, 1, 4-di (NHR)-6-chloroanthraquinone (R= H-, CH3-, C2H5-, n-C3H7-, n-C4H9-, n-C6H13-, HOC2H4-), were then prepared and their dyeing properties on Tetoron examined. The colors of dyed cloth varied from violet to greenish blue. Their dyeing affinity was good ; perticularly the dyes with R= H-, CH3-, C2H5- showed excellent affinity. The dyes with R=, HOC2H4- showed good fastness against sublimation. When compared with the corresponding 1, 4-disubstituted anthraquinones, the λmax of these dyes in ethyl alcohol shifts toward longer wave length, the value of εmax is larger and the melting point is higher. The light-fastness, however, remained almost in the same order of that of 1, 4-disubstituted anthraquinones.抄録全体を表示PDF形式でダウンロード (505K) -

ジャーナル フリー6, 7-Dichloroquinizarin was synthesized in good yield from 4, 5-dichlorophthalic anhydride and hydroquinone in the presence of sodium aluminum chloride. Disperse dyes of general formula, 1, 4-di (NHR)-6, 7-dichloroanthraquinone (R=H-, CH3-, C2H5-, n-C3H7-, n-C4H9-, n-C6H13, HOC2H4-) were then prepared and their dyeing properties on Tetoron examined. The colors of dyed cloth varied from violet to greenish blue. The dyes with R=H-, CH3-, C2H5- showed good dyeing affinity and that with R=n-C6H13-, HOC2H4- showed good fastness against sublimation. When compared with the corresponding 1, 4-disubstituted anthraquinones, the λmax of those dyes in ethyl alcohol shifts toward longer wave length, their εmax is larger, their melting points are higher, and their improved fastness against light and sublimation is also noted.抄録全体を表示PDF形式でダウンロード (523K) -

ジャーナル フリーN-Vinyl-N'-substituted phthalamides were synthesized VIA the reaction between N-vinylphthalimide and each one of n-butyl-, isobutyl-, sec-butyl-, tent-butyl-, n-amyl-, isoamyl-, 2-ethylhexyl-, and stearyl-amines . Similarly, upon treatment with N-vinylsuecinimide, n-butyl-, isobutyl, - sec-butyl-, tort-butyl-, n-amyl-, isoamyl-, n-hexyl-, and 2-ethylhexyl-amines gave the corresponding N-vinyl-N'- substituted succinamides. The results indicate that the size of the alkyl group of the amines does not affect the reactivity, tort-butyl amine being least reactive .抄録全体を表示PDF形式でダウンロード (1126K) -
