    • The invention is a process for production of C.sub.3 to C.sub.6 aldehydes by hydroformylating a mixture containing: (a) C.sub.2 to C.sub.5 olefins and mixtures thereof, and (b) (i) C.sub.2 to C.sub.5 alkynes and mixtures thereof or (ii) C.sub.3 to C.sub.5 cumulated dienes and mixtures thereof or (iii) mixtures of (i) and (ii), with CO, H.sub.2 and a solution of a rhodium complex catalyst produced by complexing Rh and an organophosphorus compound at a concentration of Rh in solution from 1 to 1000 ppm by weight. Alternatively, the solution of rhodium complex catalyst can have a P/Rh atom ratio of at least 30. Alternatively, the solution of rhodium complex catalyst can have a P/Rh atom ratio greater than the value R.sub.L defined by the formula: ##EQU1## in which R.sub.B is the P/Rh ratio sufficient for a catalytically active Rh complex, pKa.sub.TPP is the pKa value for triphenylphosphine, pKa.sub.L is the pKa value for the triorganophosphorus compound, R is the gas constant, and .DELTA.S.sub.B is 35(N-1) cal/mole/.degree.K., N is the number of P-Rh attachments per ligand molecule. The process has utility for the hydroformylation of streams that contain olefins and alkynes.

    • The invention relates to a process for selectively producing alkyl halides from alkanes, such as methane and ethane at relatively mild temperatures and pressures in an organic liquid phase in the presence of halogen and transition metal complex. The alkane may be neat if in a liquid form, or may be solubilized with a suitable organic solvent, if the alkane not a liquid at reaction conditions. The reaction is for a time, under conditions of temperature and pressure and in effective amounts that will permit the formation of alkyl halides. Optional hydrolysis to the corresponding alcohols may follow. The alkyl halides have utility as precursors for alternative fuels, such as methanol.
    • 本发明涉及在卤素和过渡金属络合物存在下,在有机液相中相对温和的温度和压力下从烷烃如甲烷和乙烷中选择性地制备烷基卤的方法。 如果在反应条件下烷烃不是液体,则烷烃可以是纯的,如果是液体形式,或者可以用合适的有机溶剂溶解。 在温度和压力的条件下反应一段时间,并且有效量可以形成烷基卤。 可以按照相应的醇进行任选的水解。 烷基卤化物可用作替代燃料(例如甲醇)的前体。
