  Structural organization and thermal properties of crystalline copper(II) N,N-cyclo-hexamethylenedithiocarbamate: A manifestation of coordination polymerism

  摘要：

  The first representative of copper(II) dithiocarbamate complexes with an unusual type of structural organization is synthesized. According to the X-ray diffraction data, the layers of noncentrosymmetric mononuclear [Cu{S2CN(CH2)(6)}(2)] and centrosymmetric binuclear [Cu(2)aub;S2CN (CH2)(6)a <<,ub;(4)] molecules alternate in the crystalline lattice of copper(II) N,N-cyclo-hexamethylenedithiocarbamate. The mononuclear and binuclear forms of the complex are observed in the 2: 1 ratio. The thermal properties of the synthesized compound are studied by thermogravimetry and differential scanning calorimetry. The final product of the thermal destruction of the complex is CuS.

  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.

  A crude acrylic acid-containing liquid containing acrylic acid is distilled in a distillation column to obtain a condensate of acrylic acid having an acrylic acid purity of 90% or more, and an oxygen-containing gas (air) containing oxygen is supplied to the condensate of acrylic acid in a reflux tank for receiving the condensate of acrylic acid. The present invention can efficiently produce high purity (meth)acrylic acid by preventing formation of a polymerized product of (meth)acrylic acid in the condensate obtained in production of high purity (meth)acrylic acid through distillation.
