    摘要: A catalyst for producing phenol consisting essentially of a nickel compound supported on a metal oxide carrier, or a catalyst for producing phenol consisting essentially of iron oxide and nickel oxide, and processes for producing phenol using either of the above catalyst. The catalysts of the invention exercise a high conversion of benzoic acid and a high selectivity to phenol, and phenol can be produced in a high yield, particularly in a high space time yield through the processes of the invention using the above catalysts. The above conversion, selectivity and space time yield can be improved by calcining the catalyst at 600.degree. to 900.degree. C.

    摘要: A front body construction of a motor vehicle includes a lower dash panel for separating an engine compartment and a cabin and a cowl portion provided on the lower dash panel such that a lower end of a windshield is supported at an upper portion of the cowl portion. The cowl portion includes an upper dash panel attached to an upper end portion of the lower dash panel so as to form a bottom wall of the cowl portion and a front cowl panel attached to an upper face of the upper dash panel so as to form a front wall of the cowl portion. The front cowl panel has, in a lateral direction of a vehicle body, opposite sides and a central portion such that space for an auxiliary unit is provided not only forwards of the front cowl panel in a longitudinal direction of the vehicle body, but also on at least one of the opposite sides of the front cowl panel. At least one of the opposite sides of the front cowl panel is disposed rearwards of the central portion of the front cowl panel in the longitudinal direction of the vehicle body, and the lower end of the front cowl panel is disposed, on at least one of the opposite sides of the front cowl panel, at a location identical with that of or rearwards of an upper end of the lower dash panel in the longitudinal direction of the vehicle body.
