    From the geographical point of view, in Japan petroleum costs comparatively cheaper than coal.Consequently it is natural that Japan's energy centre has been shifting from coal to petroleum.On the other hand, a plan to support the coal industry should be made throughout the industrial construction of whole Japan.

    The rate of formation of dicobalt-octacarbonyl from cobalt tricarbonyltetramer has been measured from 78°C to 112°C.The rate of formation of cobalthydrocarbonylfrom dicobalt-octacarbonyl also has been measured from 78°C to 108°C.These two reaction rates have been compared with the reaction rate of hydroformylation.It has been found that the rate of hydroformylation was much faster than these two reaction rates.
    From these reasons it must be avoided to contain these two steps in the mechanism of hydroformylation.The rate of hydroformylation varies inversely with the partial pressure of carbormonoxide, but it does not varies with total pressure when the ratio of hydrogen to carbonmonoxide is constant.These results have led to the following mechanism.
    [Co2(CO)8]⋅+RCH=CH2+H2 [Co2(CO)7⋅RCH=CH2⋅H2]+CO
    [Co2(CO)7⋅RCH=CH2⋅H2] [Co(CO)6RCH2⋅CH2CHO]
    [Co(CO)6⋅RCH2CH2CHO]+2CO→RCH2CH2CHO+[Co2(CO)8]
    The initial stepis in equillibrium and second is rate determing step.

  • Catalytic Hydrogenation of Humic Acid in the Presence of Raney Ni, and Reduction of Humic Acid with Solution of Sodium in Liquid Ammonia

    The humic acid, which was obtained from Onoura bituminous coal boiling with 1N HNO3, was hydrogenated in the presence of Raney Ni under hydrogen pressure.
    The results of chemical analysis and infra-red spectrum of the products indicate that the functional groups of humic acid are hydrogenated at the reaction temperature below 170°C, but, above 250°C, the chemical change is rather analogous to the artificial coalification process.Considering the hydrogenation process, it is concluded that the rational formula of Onoura humic acid, which was reported previously, is legitimate.
    The results of reduction humic acid with solution of sodium in liquid ammonia lead to the conclusion that the Onoura humic acid contains 0.9 atom of etheroxygen per molecular weight 604.

  • Semiquantitative Analysis of Occluded Gases in Coals

    The gases originally occluded in coals are accumulated by the Tepler's pump in a vaccum at 150°C and analysed by mass spectrometer.In the series of saturated hydrocarbons C3 has the minimum quantity and C4-C6 have the maximam.Methane is generlly most abundant and the quantity of the hydrocarbons over C6decreases.In the course of coalification there are two maxima at 79% C and 85% C and the other two small and unclear maxima at 79% C and 88% C.An opinion is proposed, though very speculatively, concerning to the cause of the existance of maxima from the view point that the coalification is the slow carbonisation.

  • Studies on the Property of Natural Coke (IV)
    Characteristics of Ash in Senkeki

    Washability curve of Senseki is greatly different from that of normal bituminous coal.Floth-flotation is almost meaningless for Senseki, i.e.in the use of usual reagent most of Senseki does not float, otherwise in case of using the most active reagent Senseki of rich ash content floats more easily than that of poor one.If we conduct the de-ashing of Senseki through autoclave method using concent-rated alkali solution, and then hydrochloric acid washing, its residual ash content is more than graphite.
    The constitution of residual ash is greatly different from graphite.Graphite consists of SiO2 and Al2O3, while Senseki consists of Fe2O3 and CaO in respective ash constitution.The constitution of Senseki resembles closely to that of special ash which has changed the washability curve.
    There is very familiar part with polar substances in ash of Senseki, most part of which is largely covered with bitumens carbonized by heating of lava.It might be concluded that the best washing method is Baum jig and table cleaning rather than floth-flotation and others.
