Chemical Properties
Benzyl disulfide has a powerful, burnt-caramel odor; irritating when concentrated.
Chemical Properties
White Solid
Uses
Dibenzyl disulfide has been used in lubricating oil formulations to improve thermal and aging resistance of the oil.
Antioxidant in rubber compounding, stabilizer for petroleum fractions, additive to silicone oils. The soly in oils is increased by the presence of benzyl alcohol.
Uses
Originating from Petiveria alliacea L. This compound along with the other sulfur-containing compound found in this plant display antibacterial and antifungal activity.
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.
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
From benzyl chloride and Na2S2; also from benzyl mercaptan via oxidation.
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.]
