• High yield carbonylation of halo-hydrocarbons
  申请人：STAUFFER CHEMICAL COMPANY

  公开号：EP0222460A1

  公开（公告）日：1987-05-20

  High yields of aromatic, aromatic acetic and olefinic acids, esters, amides and the like are derived from a pro­cess wherein a halo-hydrocarbon is carbonylated in the pres­ence of a palladium catalyst, a hindered amine base and phosphine in excess. The hindered amine base can comprise C₃-C₁₀ branched alkyls, cyclic compounds, or mixtures of the above. The preferred amine is N,N-diisopropylethyl amine. The preferred catalyst is PdCl₂(PPH₃)₂ with the excess phos­phine generally supplied by a compound of the formula PR¹R²R³ where R¹,R² and R³ are preferably phenyl.

  高产率的芳香族、芳香族乙酸和烯烃酸、酯、酰胺等可通过以下工艺制得：卤代烃在钯催化剂、受阻胺碱和过量膦的存在下发生羰基化反应。受阻胺基可包括 C₃-C₁₀ 支链烷基、环状化合物或上述物质的混合物。首选胺为 N,N-二异丙基乙基胺。优选催化剂为 PdCl₂(PPH₃)₂，过量的膦通常由式 PR¹R²R³ 的化合物提供，其中 R¹、R² 和 R³ 优选为苯基。

  An object of the present invention is to provide a separator which is excellent in sticking and adhesion capability with the solid electrolyte, physically strong and highly heat-resistive and to provide a solid electrolyte condenser which is excellent in the impedance characteristic and leak current characteristic. In a solid electrolyte condenser comprising an anode foil, a cathode foil, a separator, the separator is made of a nonwoven fabric containing polyester resin or its derivative manufactured by the wet method. The condenser element is formed by rolling the anode foil and the cathode foil together with the separator between them. The solid electrolyte is provided between the anode foil and the cathode foil of the condenser element.

  本发明的目的是提供一种与固体电解质的粘附能力极佳、物理强度高且耐热性强的隔膜，以及一种阻抗特性和泄漏电流特性极佳的固体电解质电容器。在由阳极箔、阴极箔和隔膜组成的固体电解质冷凝器中，隔膜是由含聚酯树脂或其衍生物的无纺布制成，采用湿法制造。冷凝器元件由阳极箔和阴极箔以及它们之间的隔膜一起卷成。固体电解质位于冷凝器元件的阳极箔和阴极箔之间。
