Benzyl mercaptan Chemical Properties,Uses,Production
Chemical Properties
Benzyl mercaptan has repulsive, garlic-like odor. It oxidizes in air to dibenzyl disulfide.
Occurrence
Reported found in coffee.
Uses
Benzyl mercaptan can be used as:
- A nucleophilic reagent in the cleavage of proanthocyanidins into their constitutive subunits.
- A reactant in the synthesis of dithiocarboxylic esters in the presence of phosphorus pentasulfide as a catalyst.
- A modifier to functionalize the surface of CNT for enhanced interaction with Pt-nanoparticles.
Preparation
From benzyl chloride and potassium hydrosulfide.
Hazard
Skin irritant.
Safety Profile
Poison by inhalation and intraperitoneal routes. Moderately toxic by ingestion. An eye irritant. Questionable carcinogen with experimental tumorigenic data. Flammable when exposed to heat or flame. Can react vigorously with oxidizing materials. To fight fire, use foam, CO2, dry chemical, water spray, mist, fog. When heated to decomposition and on contact with acid or acid fumes it emits highly toxic fumes of SOx. See also SULFIDES and MERCAPTANS.
Purification Methods
Purify benzyl mercaptan via the mercury salt [see Kern J Am Chem Soc 75 1865 1953], which crystallises from *benzene as needles (m 121o), and then dissolve it in CHCl3. Pass H2S gas through the solution to regenerate the mercaptan. The HgS that precipitates is filtered off and washed thoroughly with CHCl3. The filtrate and washings are evaporated to remove CHCl3; then the residue is fractionally distilled under reduced pressure [Mackle & McClean, Trans Faraday Soc 58 895 1962]. [Beilstein 6 IV 2632.]
