Dibenzyl disulfide Structural

What is Dibenzyl disulfide?

Chemical properties

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.

The Uses of Dibenzyl disulfide

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.

Definition

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.

Preparation

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.
synthesis of Dibenzyl disulfide
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.

What are the applications of Application

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.

General Description

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.

Purification Methods

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.]
