• Synthesis, Characterization Studies and Bond Valence Sum (BVS) analysis on 2:1 Adducts Involving Zinc(II)dithiocarbamates and 4,4’-Bipyridine

  2:1 adducts involving [Zn(dtc)2]2 (dtc- = pipdtc-, H10C5NCS-2; dnpdtc-, (H3CCH2CH2)2NCS-2; dedtc-, (H5C2)2NCS-2; dmdtc-, (H3C)2NCS-2; nmedtc-, HOCH2CH2(CH)3NCS-2; deadtc-, (HOCH2CH2)2NCS-2) and 4,4' – bipyridine were prepared and characterized by elemental analyses, IR, UV-Visible, Cyclic voltammetric and thermal studies. IR spectra of the complexes show the reduction in the thioureide stretching frequency due to the increase in coordination around the zinc ion and the resultant increase in electron density. The charge transfer transitions are observed in the region 260 – 320 nm by electronic spectra. Thermal studies show a single stage weight loss. The cyclic voltammetric study on the complexes  show an increase of electron density on zinc in the adducts compared to [Zn(dtc)2]2. The bond valence sum(BVS) analysis shows the  values to be close to '2', which is equivalent to the formal oxidation state of zinc in the zinc complexes.

  2:1 加合物涉及 [Zn(dtc)2]2 (dtc- = pipdtc-, H10C5NCS-2; dnpdtc-, (H3CCH2CH2)2NCS-2; dedtc-, (H5C2)2NCS-2; dmdtc-, (H3C)制备了 2NCS-2; nmedtc-、HOCH2CH2(CH)3NCS-2; deadtc-、(HOCH2CH2)2NCS-2) 和 4,4' – 联吡啶，并通过元素分析、红外、紫外-可见、循环伏安和热分析进行表征。研究。配合物的红外光谱显示，由于锌离子周围配位的增加以及由此导致的电子密度的增加，硫脲伸缩频率降低。通过电子光谱在 260 – 320 nm 区域观察到电荷转移跃迁。热研究显示单阶段减重。对配合物的循环伏安研究表明，与 [Zn(dtc)2]2 相比，加合物中锌上的电子密度有所增加。键价和 (BVS) 分析显示值接近“2”，这相当于锌配合物中锌的形式氧化态。

  A lubricating oil composition prepared by compounding a base oil with a metal dithiocarbamate represented by general formula (I) and an oil-soluble amino compound, wherein M represents zinc, copper, nickel, iron, cadmium, silver, lead, antimony, tin or bismuth; and R₁, R₂, R₃ and R₄ represent each independently a C₁ to C₁₃ oleophilic group provided that each group has on average more than one up to four carbon atoms. The composition contains scarcely any or no phosphorus and is excellent in wear resistance, extreme-pressure properties, frictional characteristics, oxidation stability and coking resistance, thus being suitably usable as a lubricating oil for internal combustion engines of automobiles.

  A process of recycling used sulphur-cured elastomeric materials comprising masticating the said elastomeric materials at temperatures below 50°C with a novel chemical mixture which is capable of initiating proton exchange in a controlled manner and thereby open up or delink the vulcanised network of the elastomeric materials. The novel chemical mixture is made from the zinc salt of dimethyldithiocarbamate and mercaptobenzothiazole in the molar ratio in the range of 1:1 to 1:12 dispersed in diols and in the presence of stearic acid, zinc oxide and sulphur. This mixture, which may be termed the 'Delink' when blended with tyre crumbs or any other vulcanised crumbs in concentrations of 6 parts binder per 100 parts of rubber crumbs on a mill effectively delinks the vulcanised network and renders the compound ready for moulding and vulcanisation. The total milling period, which occurs at temperatures below 50°C, takes only 7 to 10 minutes. Alternatively, the binder and tyre crumbs could be first mixed in an intermix and subsequently milled in an open mill. The obtained recycled rubber compounds display satisfactory levels of physical and dynamic characteristics. Such compounds can be directly used in moulded goods or in admixture with fresh compounds in tyres and related areas.
