    摘要： A folding work platform apparatus is used on a support surface and includes a work platform table and at least three legs. The work platform table has a top surface and a bottom surface disposed opposite the top surface and a side wall disposed between the top and bottom surfaces to define a thickness. The work platform table might have a groove formed into the top surface that extends longitudinally along a longitudinal axis. The at least three legs movably adjoin the bottom surface of the work platform table and are movable to and between a folded state wherein the at least three legs extended from the bottom surface generally parallel with one another and an extended state wherein the at least three legs extend from the bottom surface generally angularly away from the bottom surface and from one another for supporting the work platform table on the support surface.

    摘要： Aliphatic and aromatic amines are produced by reacting an olefin with either ammonia or a primary or secondary amine in the presence of a catalytic amount of ruthenium or iron compound catalyst. The reaction is carried out in the liquid phase using an inert liquid, a product amine, or one of the reactants as a solvent. The temperatures used are 100.degree. to 250.degree. C. and the pressures are at least autogenous and up to 12,000 psig.

    摘要： A solid catalyst composition for the vapor phase conversion of methanol and ethanol to higher linear primary alcohols (e.g., n-propanol) is made up of particles of an inert, high surface area support (e.g., gamma-aluminum oxide) impregnated with an inorganic base promoter (e.g., a basic salt of an alkali metal) and a platinum group metal (e.g., rhodium). The production of the higher linear primary alcohols is carried out by contacting a mixture of methanol, ethanol, and a carrier gas (e.g., synthesis gas) with the catalyst at a temperature of between 200.degree. and 400.degree.C. and pressure of between 1000 and 5000 p.s.i.g. at a space velocity of between 2000 and 10,000 hr.sup.-.sup.1.
