Usage

General Description

Didodecyl disulfide is a chemical compound consisting of two dodecyl groups bonded to a sulfur atom. It is commonly used as a lubricant additive and in the production of polymers and plastics. Its primary function is to provide lubrication, reduce friction, and improve the wear resistance of materials. Didodecyl disulfide is also used in the formulation of metalworking fluids, greases, and industrial lubricants. It is known for its ability to withstand high temperatures and harsh operating conditions, making it a valuable ingredient in a wide range of industrial and automotive applications. Additionally, it has some potential applications in the pharmaceutical and cosmetic industries due to its antimicrobial properties.

SYNTHESIS OF MONOFUNCTIONAL THIURAM ACCELERATOR

The present invention provides a route for synthesizing monofunctional thiuram compounds that is safe, environmentally friendly, and cost effective. This method specifically involves synthesizing a monofunctional thiuram by (1) reacting a tetraorganylthiuram disulfide with an organyl mercaptan to produce the monofunctional thiuram and a dithiocarbamate metal salt or a dithiocarbamate metalloid salt under basic conditions, (2) separating the monofunctional thiuram in an organic phase from the dithiocarbamate metal salt or the dithiocarbamate metalloid salt in an aqueous phase, and (3) recovering the monofunctional thiuram from the aqueous phase. The monofunctional thiuram compounds made in accordance with this invention are of particular value as accelerators for use in the vulcanization of rubber. The use of these monofunctional thiuram compounds as accelerators provides good cure rates and as well as good scorch safety.

Unsymmetrical Disulfides Synthesis via Sulfenium Ion

An umpolung approach for the synthesis of unsymmetrical disulfides via sulfenium ion is reported. In situ generated electrophilic sulfenium ion from electron-rich thiols reacted with second thiols to yield unsymmetrical disulfides. Using an iodine catalyst and 4-dimethylaminopyridine (DMAP)/water as promoter, the target syntheses were achieved in one pot under aerobic condition.

DDQ-mediated synthesis of functionalized unsymmetrical disulfanes

We developed a simple and efficient method for the synthesis of functionalized unsymmetrical disulfanes under mild conditions in good yields. The designed method is based on the reaction of bis(5,5-dimethyl-2-thioxo-1,3,2-dioxaphosphorinan-2-yl)disulfane with thiols in the presence of 2,3-dichloro-5,6-dicyanobenzoquinone (DDQ). The developed method allows the preparation of unsymmetrical disulfanes bearing additional hydroxy, carboxy, or amino functionalities.
