    Notes: The antimicrobial activity of a variety of aliphatic diols and their esters has been investigated. Inhibition of growth of Bacillus subtilis 60015 was found to depend on chain length and position of the hydroxyl groups. 1,2-diols were more effective than 1,3diols. Esterification also affected antimicrobial activity. Studies with membrane vesicles prepared from B. subtilis indicated that inhibition of amino acid transport is a primary antimicrobial effect of diols and their esters.

    STORAGE DETERIORATION OF FREEZE-DRIED AVOCADO PUREE AND GUACAMOLE (1970)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 35 (1970), S. 0 
    Details
    ISSN: 1750-3841

    Notes: SUMMARY— The effect of storage temperature, time and atmosphere on the chemical and organo-leptic characteristics of freeze-dried avocado puree and guacamole was studied using Waldin, Lula and Booth-8 varieties of avocado. Oxidation rates were slower at 21°C than at 38°% storage and nitrogen atmospheres reduced the peroxide formation. Significant differences existed in oxidation rates between avocado varieties and also between guacamole and avocado puree in some instances. A logarithmic relationship was found between peroxide values and storage time in air. Guacamole made with Lula avocados was unacceptable after 3 weeks of storage in air at 38°C. Samples stored in nitrogen at 38°C ware unacceptable at the end of 7 weeks. Samples stored in air at 21°Cwere acceptable after 12 weeks and those stored in nitrogen at 2l°C after 15 weeks. A commercial BHA antioxidant reduced the oxidation rate of Lula puree but did not increase shelf life in air storage at 38°C. Peroxide values were of no use in predicting acceptability, since organoleptic deterioration could occur without any peroxide increase.

    Description / Table of Contents: Abstract Различные катализаторы были приготовлены пропитыванием коммерческой окиси алюминия растворами, содержащими комплексный ион — дихлор-бис ( (трихлорстаннато)-платинат(II) [PtCl2(SnCl3)2]−2. После восстановления, каталитическая активность в реакции восстановления бензола изменялась в 1–20 раз. Последняя прямо пропорциональна стабильности комплекса в пропитывающем растворе.
    Notes: Abstract Various catalysts were prepared by impregnating a commercial alumina with solutions containing the complex dichlorobis(trichlorostannato)platinate (II). [Pt Cl2 (SnCl3)2]2−. After reduction, 1–20 fold variations in the catalytic activity in benzene hydrogenation were observed in direct proportion to the stability of the complex in the impregnating solution.

Results show that, compared with platinum, the activity of bimetallic catalysts is several times lower while the selectivity to hydrogenolytic products increases from 72 to 100%.

    Description / Table of Contents: Abstract Было исследовано гидрирование бензола, толуола, о-, м- и п-ксилолов на катализаторах Pt, Pd и Pt−Pd/Al2O3. На основе экспериментальных данных было установлено, что при добавлении Pd к катализатору Pt происходит уменьшение активности и изменение селективности. Это объясняется образованием электронообедненных и электрониообогащенных металлических частиц.
    Notes: Abstract Hydrogenation of benzene, toluene, o,m and p-xylene over Pt, Pd and Pt−Pd/Al2O3 catalysts has been studied. Experimental data show that when Pd is added to Pt catalysts, a decrease in activity and changes in selectivity occur. This is explained by the formation of electron-deficient and electrorich metallic species.

    Description / Table of Contents: Abstract Дисперсность металла для образцов Ru/Al2O3 была определена титрованием H2−O2 и адсорбцией CO. Во избежание образования поликарбонилов Ru−CO, поверхность рутения заполняется водородом. Такая процедура дает хорошее согласие между данными титрования H2−O2, адсорбции CO и электронной микроскопии.
    Notes: Abstract Hydrogen-oxygen titration and carbon monoxide adsorption on Ru/Al2O3 samples were employed to determine metal dispersity values. To avoid Ru−CO polycarbonyl formation, before CO adsorption, the ruthenium surface was precovered with hydrogen. By this procedure, good agreement between H2−O2 titration, CO adsorption and electron microscopy is obtained.
