摘要： Compositions of matter are disclosed which are highly useful in hydroformylation processes. The compositions are non-charged, non-chelated bis- and tris-(alkyl diaryl phosphine) rhodium carbonyl hydrides. The substituents of the alkyl group include heteroorganic radicals containing ether, ester, keto and hydroxy oxygen, phosphine oxide and phosphorus ester phosphorus, amine, amide, amine oxide and heterocyclic nitrogen groups.These compositions are highly stable and selective catalysts for the hydroformylation of olefins under certain conditions. The disclosed catalyst systems contain a large excess of phosphine ligand and employ alpha-olefin plus synthesis gas reactant mixtures having a high H.sub.2 /CO ratio at relatively low pressures. They produce mostly aldehydes derived from terminal attack on the alpha-olefin reactant. In the case of low olefins, such as butene-1, the products can be advantageously removed in a continuous manner, as distillate components from a ligand reaction mixture kept at an elevated temperature and continuously fed by an appropriate mixture of the reactants.

摘要： A method to synthesize styrene from toluene by: (a) oxidizing toluene to form oxygenated toluene derivatives; (b) carbonylating said oxygenated products in the presence of a carbonylation catalyst and preferably a halogen promoter to produce phenylacetic acid; (c) hydrogenating said phenylacetic acid to synthesize phenylethyl alcohol; and (d) dehydrating said phenylethyl alcohol to obtain a high yield of styrene. In a preferred embodiment, a two-step, three-phase separation process can be employed for the separation and recovery of the phenylacetic acid formed in step (b) from the carbonylation catalyst and the halogen promoter which may have been employed in the carbonylation step (b) mentioned above by first separating the carbonylation product mixture into a gas-phase mixture and a liquid-phase mixture containing the phenylacetic acid, the carbonylation catalyst and the promoter; and then crystallizing the phenylacetic acid contained in the liquid-phase mixture in order to separate and thereafter recover the crystallized phenylacetic acid from the remaining liquid-phase mixture containing the carbonylation catalyst and the promoter.
