  摘要：

  在室温和113 K下，在氯仿-乙醇混合物中记录了七种二硫代氨基甲酸铜的esr光谱。已发现向这些二硫代氨基甲酸酯中添加一定范围的盐会破坏该配合物，形成混合配体配合物，[Cu（S 2 CNR 2）X]，具有新的esr光谱。当X为Cl或Br时，观察到未配对电子与单个卤素原子核的其他相互作用。[Cu（S 2 CNEt 2）Cl]络合物形成偶极-偶极耦合二聚体，并且获得了该二聚体的ΔM s = 2吸收率的计算机模拟。

  An object of the present invention is to provide a method for producing (meth)acrylic acid or (meth)acrolein by conducting a gas phase catalytic oxidation reaction with an oxygen-containing gas using as a raw material at least one substance to be oxidized selected from propylene, propane, isobutylene and (meth)acrolein using a multi-tubular reactor, which enables a high yield and stable production even when operating constantly with supplying the raw material in the maximum supply amount acceptable by the reactor or an amount close thereto. The invention is a method for producing (meth)acrylic acid or (meth)acrolein wherein, at the time of a start-up of the reaction, for a period of at least 20 hours or more after the supply amount of the raw material to the reactor per unit time reached 30% or more of the acceptable maximum supply amount of the raw material per unit time, the supply amount of the raw material per unit time is kept at 30% or more and less than 80% of the acceptable maximum supply amount.

  [CuII(S2CNnPr2)2] can be achieved by reaction with Cu(I) ions and borohydride. The hydride release and regeneration of CuI8 was monitored by UV–visible titration experiments. To our knowledge, this is the first time that hydride encapsulated within a copper cluster can be released as H2 via chemical means. All complexes have been fully characterized by 1H NMR, FT-IR, UV–vis, and elemental analysis, and molecular structures

  In a process for producing (meth)acrylic acid comprising contacting a reaction gas containing (meth)acrylic acid obtained by gas-phase catalytic oxidation with an absorbent solvent to prepare a (meth)acrylic acid solution; and introducing the (meth)acrylic acid solution into a distillation column to purify (meth)acrylic acid, after a dissolved oxygen concentration in the (meth)acrylic acid solution to be introduced into the distillation column is adjusted to not less than 12 ppm by weight, the (meth)acrylic acid solution is fed to the distillation column. In addition, upon an azeotropic dehydration distillation step, a phenol-based polymerization inhibitor is fed to an azeotropic dehydration distillation column from a position not lower than a raw material feed stage thereof, and a copper-based polymerization inhibitor is fed to the azeotropic dehydration distillation column from a position lower than the raw material feed stage. According these methods, the production of polymers of (meth)acrylic acid and polymerization clogging in the distillation column are prevented, so that it is possible to stably purify (meth)acrylic acid by distillation for a long period of time.

  在生产（甲基）丙烯酸的过程中，包括将通过气相催化氧化获得的含有（甲基）丙烯酸的反应气体与吸收溶剂接触，制备（甲基）丙烯酸溶液；并将（甲基）丙烯酸溶液引入蒸馏塔以纯化（甲基）丙烯酸，在将要引入蒸馏塔的（甲基）丙烯酸溶液中溶解氧浓度调整至不低于12 ppm重量后，将（甲基）丙烯酸溶液送入蒸馏塔。此外，在共沸脱水蒸馏步骤中，从不低于原料进料阶段的位置向共沸脱水蒸馏塔中加入苯酚类聚合抑制剂，并从低于原料进料阶段的位置向共沸脱水蒸馏塔中加入铜基聚合抑制剂。通过这些方法，可以防止（甲基）丙烯酸的聚合物生成和蒸馏塔中的聚合物堵塞，从而可以长时间稳定地通过蒸馏纯化（甲基）丙烯酸。
