Alkyl Phenol Disulfide

Alkyl phenol disulfide accelerator is commonly used in combination with other accelerators to cure halobutyl-based compounds. This accelerator also imparts some tackiness to the compound as well, which helps in the construction of a tire or other rubber products. 

There is no official standard classification, but there are several different commercial grades available. 

It is used as an accelerator usually in compounds based on halobutyl rubber to give better adhesion to other compounds based on general-purpose elastomers. 

Other cure systems can be substituted after significant evaluations and factory trials.

Sulfur reacts with chlorine to form sulfur monochloride (SjClj), which is used to synthesize DTDM (sulfur donor for efficient cures), alkyl phenol disulfide (accelerator), and vulcanized vegetable oil (WO), which is used as a processing aid for rubber. 

Sulfur monochloride reacts with p-alkyl phenol to produce alkyl phenol disulfide accelerator. 

The alkyl phenol disulfides are mainly used in tire inner liners for heat resistance, along with a conventional accelerator system. The R group is f-butyl or amyl. In addition to donating sulfur for cross-linking purposes, these materials can also function as bisphenolic curatives (see Section 13.6).

Other evidence from carbon-13 magnetic resonance studies of the carbon disulfide extract of coal also favors the occurrence of small-ring systems. The mean structural unit appears to consist of two-to-three ring condensed aromatic systems with 40% of the available aromatic carbons bearing alkyl, phenolic, and/or naphthenic groups. Indeed, the mass spectrum of the extract indicated the presence of alkyl aromatic compounds having from 1 to 10 or more alkyl carbons per molecule. 

A common feature of the stabilizers of this class is the presence of a sulfur atom, bonding two molecules of phenol or its alkyl derivatives in the ortho- or para-positions to the hydroxy group. Depending on the number of sulfur atoms contained in the stabilizer molecule, they can be separated into bis-phenol monosulfides and bis-phenol disulfides. 

When thionyl chloride is used, diaryl sulfoxides are usually the main products. Unsymmetrical diaryl sulfides can be obtained by treatment of an aromatic compound with an aryl sulfenyl chloride (ArSCl) in the presence of a trace amount of iron powder.Aromatic amines and phenols can be alkylthiolated (giving mostly ortho product) by treatment with an alkyl disulfide and a Lewis acid catalyst. With certain substrates (primary amines with a chloro group, or a group not replaceable by chloro, in the para position), treatment with S2CI2 and NaOH gives thiophenolate salts ... 

The dianion (307), easily prepared from phenols and carbon disulfide in the presence of potassium hydroxide in DMSO, can be alkylated with 1,2-dibromoethane to form the 1,3-dithiole derivatives (308) (65LA(684)37).
