Octadecanethiol Chemical Properties,Uses,Production
Chemical Properties
white powder with an extremely unpleasant smell
Uses
Organic intermediate, synthetic rubber processing.
Uses
1-Octadecanethiol (ODT) is used to deposit thiolated molecules onto the surface of gold substrates, such as SAMs on gold quartz crystal resonators, on the tip of atomic force microscope probes, capacitive sensors.
Uses
ODT is used in the surface modification of gold nanoparticle (AuNPs)/Nickel (Ni) foam conjugate for the preparation of a 3D surface enhanced Raman spectroscopy(SERS) substrate for the detection of organic pollutants. It may also be used enhance the superhydrophobic properties for different materials like nano-sized copper films, graphene and silica for different applications like mercury detection and electrochemical analysis.
General Description
1-Octadecanethiol (ODT) is a water soluble sulfur compound with an 18 carbon alkyl chain, which forms a strong hydrophobic assembly with transition metals, like gold .It forms self-assembled monolayers (SAMs) on the surface of such transition metals. The thiol membrane when covalently bonded with the surface of the metal electrode, it shows electrostriction phenomenon leading to variation in capacitance.ODT SAMs have a hydrophobic surface with contact angle of 102oC.
Reactivity Profile
Octadecanethiol is non-flammable but combustible (Flash point >100°F and <140°F). Incompatible with oxidizing agents, strong acids and strong bases, alkali metals, and nitric acid. Can react with water, steam or acids to produce toxic and flammable vapors. Reacts violently with powerful oxidizing agents such as calcium hypochlorite(Ca(OCl)2) to generate SOx. Reacts with hydrides to form flammable H2 gas; reacts with halogenated hydrocarbons to yield HX. Reacts exothermically with aldehydes. Emits toxic compounds of sulfur when when heated to decomposition.
Hazard
Strong irritant.
Flammability and Explosibility
Not classified
