    Notes: Abstract The activity and selectivity of 10 % Co/support and 10 % Ni/support catalysts (where the support is A12O3, SiO2, C) in the synthesis of hydrocarbons from CO2 and H2 were studied. The extent of conversion of the starting mixture and the yield of methane were shown to depend on the composition of the catalytic system. Cobalt catalysts with various types of carbons as supports are the most active. They permit the synthesis of methane in yields up to 70 % of the theoretical value.

    Notes: Summary 1. It was found for the first time that the pyrogenetic transformations of heptane in molten aluminum and in molten sodium proceed in a selective manner which depends on the identity of the metal. 2. The extent of the thermal decomposition of heptane is increased by the use of aluminum: in thermal pyrolysis the conversion of heptane (57%) is less than the conversion in contact with aluminum (99%) by nearly one-half. 3. Sodium has a powerful retardant action on the thermal decomposition of heptane: the conversion of heptane in contact with sodium attains only 5–6% at 600–800°. 4. The gas obtained by the pyrolysis of heptane in molten aluminum contains 40–44% of olefins and 12.22% of hydrogen. On the other hand, the pyrolysis of heptane in molten sodium is accompanied by the formation of gas containing 75–85% of hydrogen without any appreciable amount of olefins.

    Notes: Summary 1. It was found that the pyrogenetic transformations of heptane in the molten metals aluminum, tin, and sodium proceed selectively in a way dependent on the nature of the metal. 2. Aluminum and tin accelerate the cracking of heptane. Sodium and potassium hydroxide exert a powerful retarding action on the cracking of heptane. 3. The mechanism of the action of inhibiting additives appears to amount to chain termination due to the reaction of alkali metals with free radicals or to the saturation of hydrogen liberated by reaction with hydrocarbons. 4. Alkali-metal hydroxides may be reduced by hydrocarbons to metals, which then react by the mechanism indicated.

    Notes: Summary 1. A number of catalysts have been investigated in the phenol—isobutene alkylation reaction under comparable conditions, these catalysts including BF3, H3PO4· BF3, AlCl3, H2SO4, and AlCl2 · HSO4; it was shown that boron fluoride, taken in 0.8–1% quantity, is the most active catalyst and gives the highest yield of p-tert-butylphenol. 2. An investigation has been made of the effect of various factors on alkylate yield and composition in phenol isobutene alkylation with boron fluoride. The yield of p-tert-butylphenol reaches 78–88% of the theoretical.

    Notes: Conclusions 1. The possibility is shown of preparing antistatic additives based on salicylic acid, theβ -diketones of ferrocene and CTM and higher carboxylic acids, which are not inferior in their properties to foreign additives. 2. The additives based on salicylic acid, theβ -diketones of ferrocene and CTM, and oleic acid increase the electrical conductivity of petroleum products by factors of 103–104, which enables the accumulation of static electrical charges in refined petroleum products to be prevented.

    Notes: Conclusions 1. A process was developed for obtaining alkyl carbametes from urea and the corresponding alcohols in the presence of an aluminosilicate catalyst. 2. Optimal regions for synthesis of methyl carbamate were determined by the Box-Wilson method of multifactor systematization. 3. The effect of various factors (temperature and length of reaction, ratio of initial reagents, space velocity of raw-material introduction, quality of the initial raw material, and length of operation of the catalyst) on the yield of methyl carbamate were studied. 4. C2-C5 alkyl carbamates were obtained in yields of 75–79% of the theoretical under the optimal conditions found for methyl carbamate.
