Metal-sulphur Bond Enthalpy Determination of Di-n-Butyldithiocarbamate Chelates of Zinc, Cadmium and Mercury

The standard molar enthalpies of formation of crystalline n2)2> (M = Zn, Cd or Hg), determined through reaction-solution calorimetry at 298.15 K, were found to be -471.23 +/- 3.90, -440.74 +/- 3.79 and -319.29 +/- 3.38 kJ mol-1, respectively.The corresponding molar enthalpies of sublimation, 107 +/- 3, 123 +/- 3 and 195 +/- 3 kJ mol-1, were estimated by means of differential scanning calorimetry.From the standard molar enthalpies of formation of the gaseous chelates, -364 +/- 5, 318 +/- 5 and -124 +/- 5 kJ mol-1, the homolytic and heterolytic mean metal-sulphur bond enthalpies were calculated.The homolytic enthalpies decrease from zinc to mercury, while the heterolytic values are almost constant.

Controllable growth of semiconductor heterostructures mediated by bifunctional Ag2S nanocrystals as catalyst or source-host

We demonstrate that Ag2S nanocrystals are the bifunctional mediator for controllable growth of semiconductor heterostructures including more complicated multisegments heterostructures in solution-phase, which is a new type of nanomediator and quite different from the metal nanoparticle catalyst. The intrinsic high Ag+ ion mobility makes Ag2S nanocrystals not only exhibit excellent catalytic function for growth of metal sulfide heterostructures but also act as a source-host for growth of ternary semiconductor heterostructures, for example, Ag2S-AgInS2. The semiconductors grow epitaxially from or inward in Ag2S nanocrystals forming single-crystalline heterostructures. Moreover, the method developed here also can construct multisegments heterostructures, for example, Ag2S-CdS-ZnS, AgInS2-Ag2S-AgInS2. The interfacial structure is still stable even if the lattice mismatch is quite large, which is a unique feature of this method.

The present invention relates to rubber vulcanization accelerator field, in particular, provides a dibutyl dithiocarbamate acid preparation method of zinc, to contain zinc oxide, two-butylamine, dispersant and 1st of the organic solvent in the reaction solution dropwise carbon disulfide reaction, after the reaction to obtain the dibutyl dithiocarbamate acid zinc, wherein the 1st organic solvent insoluble in water, and the resulting dibutyl dithiocarbamate acid zinc not soluble in or soluble in 1st organic solvent. The method adopts a non-water solvent method preparation dibutyl dithiocarbamate acid zinc, avoids the generation of salt-containing waste water, because the 1st organic solvent is insoluble in water, it can be with a minute fluid operation the two are separated, 1st organic solvent after removing water can be reused, reducing solvent cost while increasing the yield of the product. The above method is simple in operation, avoids the generation of salt-containing waste water, it is a clean environmental protection of the new method, the method is easily applied to large-scale production practice among them.
