  A process is disclosed for producing &agr;-methylstyrene, acetone, and phenol wherein the amount of &agr;-methylstyrene produced may be controlled by selectively converting a portion of the cumene hydroperoxide to dimethyl phenyl carbinol, the hydrated form of &agr;-methylstyrene. The dimethyl phenyl carbinol thus produced will lead to increased production of &agr;-methylstyrene upon dehydration in the acid cleavage unit of the phenol plant. By controlling the fraction of the cumene hydroperoxide reduced to dimethyl phenyl carbinol, the amount of &agr;-methylstyrene produced in the plant can be continuously set to meet the demand of the market for &agr;-methylstyrene. Also disclosed is a non-acidic catalyst for reduction of cumene hydroperoxide.

  揭示了一种生产α-甲基苯乙烯、丙酮和酚的方法，其中通过选择性地将部分双甲苯过氧化氢转化为二甲基苯基甲醇（α-甲基苯乙烯的水合形式），可以控制所生产的α-甲基苯乙烯的量。因此，在酚厂的酸解离装置中，通过脱水将产生的二甲基苯基甲醇将导致α-甲基苯乙烯的增加生产。通过控制将双甲苯过氧化氢还原为二甲基苯基甲醇的比例，可以持续地设置工厂中生产的α-甲基苯乙烯的量，以满足市场对α-甲基苯乙烯的需求。还揭示了一种用于还原双甲苯过氧化氢的非酸性催化剂。

  A compound comprising a sulfonated triorganophosphine of formula R1R2PR3[SO3M)]n, wherein R1 and R2 are selected individually from alkyl, aralkyl, and alicyclic groups; wherein R3 represents a branched divalent or polyvalent, alkylene or alicyclic radical that is bonded to the phosphorus atom and to one or more sulfonate substituents, and further wherein R3 does not contain any aryl moieties; M represents a monovalent cation; and n is an integer representing a total number of sulfonated substituents. The compound is useful as a ligand in transition metal-ligand complex catalysts that are capable of catalyzing the hydroformylation of an olefinically-unsaturated compound with carbon monoxide and hydrogen to form one or more corresponding aldehyde products. The ligand is incapable of alkyl-aryl exchange, thereby leading to reduced ligand usage and improving ligand and transition metal, e.g., rhodium, recovery and recycling, as compared with prior art ligands.

  一种化合物，包括公式R1R2PR3[SO3M)]n的磺化三有机膦，其中R1和R2分别从烷基、芳基烷基和脂环基中选择；其中R3代表与磷原子和一个或多个磺酸取代基结合的支链二价或多价、烷基或脂环基团，且R3不含任何芳基；M代表一价阳离子；n是表示磺化取代基总数的整数。该化合物可用作过渡金属-配体复合催化剂中的配体，能够催化烯烃不饱和化合物与一氧化碳和氢反应，形成一个或多个相应的醛产物。该配体无法进行烷基-芳基交换，从而减少配体的使用量，改善配体和过渡金属（例如铑）的回收和循环，与现有技术的配体相比。
