• 外観

  白色〜わずかにうすい褐色, 結晶

• 溶解性

  熱エタノール及びアセトンに溶けやすく、水に極めて溶けにくい。

• 用途

  酸化防止剤、安定剤、香料材料。

• 化学的特性

  Benzyl disulfide is a pale yellow leafy or small leafy crystals that has a powerful, burnt-caramel odor; irritating when concentrated. Boiling point >270°C(decomposition). Several insoluble in water, soluble in hot ethanol and ether.

• 使用

  Dibenzyl disulfide has been used in lubricating oil formulations to improve thermal and aging resistance of the oil. It is used an antioxidant in rubber compounding, stabilizer for petroleum fractions, additive to silicone oils. The soly in oils is increased by the presence of benzyl alcohol.

• 主な応用

  Dibenzyl Disulfide (DBDS) is one of several sulfur compounds known to cause copper corrosion in transformers under certain circumstances. Originating from Petiveria alliacea L. This compound along with the other sulfur-containing compound found in this plant display antibacterial and antifungal activity.

• 製造方法

  Dibenzyl disulfide is synthesized from benzyl chloride and Na2S2; also from benzyl mercaptan via oxidation.
  Md. Tajbakhsh et al. (2004) synthesized disulfide from thiols by oxidation with 2,6- DCPCC in acetonitirle at room temperature. For synthesis of DBDS, they used benzyl mercaptan. In 8 min, 96% yield was obtained.
  
  Vivek Polshettiwar et al. (2003) obtained disulfide from reaction of alkyl halide with reagent (C6H5CH2N(Et)3)6Mo7S24 in presence of CHCl3 at room temperature. Pure disulfide was obtained by purification by column chromatography method on silica gel. 89% yield was obtained.

• 定義

  ChEBI: Dibenzyl disulfide is an organic disulfide that results from the formal oxidative dimerisation of benzyl thiol. It has a role as a metabolite. It is an organic disulfide and an organic aromatic compound.

• 一般的な説明

  Dibenzyl Disulfide (DBDS) also called Benzyl disulfide is an aromatic disulfide with molecular formula C14H14S2. It has a structural unit, which consists of a linked pair of sulfur atoms. It is insoluble in water whereas soluble in hot methanol, benzene, ether and hot ethanol. Large disulfides-linked agglomerates are rifely found in proteins and many other biologically active molecules.

• Solubility in organics

  Poorly soluble in cold alcohol, soluble in hot alcohol and in oils.

• 純化方法

  Crystallise the disulfide from EtOH (m 77o), pet ether or CS2 (m 72o) or distil it. The AgNO3 complex has m 103o. [Beilstein 6 H 465, 6 I 229, 6 II 437, 6 III 1635, 6 IV 2760.]
