What is 1-Dodecanethiol?
1-Dodecanethiol (DDT) is an alkyl mercaptan, which can form a self-assembled monolayer (SAM) and can be used as an organic sulfur source with balanced physical and chemical properties.
1-Dodecanethiol (C12H26S, CAS No. 112-55-0), also known as n-dodecyl mercaptan, is a transparent liquid. Melting point: – 7 ℃, flash point 87 ℃. Stable under normal temperature and pressure. Store in a cool and dry place. Keep the container closed when not in use. It can cause severe skin burns and eye damage. It may cause skin allergic reactions. It is highly toxic to aquatic organisms and has long-term lasting effects.
Bromododecane, thiourea and 95% ethanol were heated to reflux reaction, then sodium hydroxide solution was added and heated. After the reaction is completed, cool and stand for layering, and the oil layer is crude mercaptan. After washing, drying, distillation and vacuum distillation, the crude product is n-dodecyl mercaptan.
1-Dodecanethiol Uses
- 1-Dodecanethiol can be utilized as a chain transfer representative in the polymerization of methyl methacrylate. For instance, the result of 1-dodecyl mercaptan as a chain transfer agent on the molecular weight of poly (methyl methacrylate) has been studied. The transfer constants of 1-dodecyl mercaptan at various temperatures were determined; After that the activation energy and also frequency aspect of Arrhenius equation with transfer constant are gotten.
- 1-Dodecanethiol is a natural molecular sulfur that has actually been made use of as a sulfur source for the manufacturing of cadmium sulfide (CDS) “magic dimension” quantum dots (msqds). For instance, CdS quantum dot (QD) nanoparticles have made use of cadmium salt and also 1-dodecyl mercaptan (a natural sulfur) as cadmium and also sulfur sources, respectively, and also long-chain organic acids (myristic acid, lauric acid, or stearic acid). The acid also has a twin duty as a surface topping ligand and also a solubility control representative. Organic sulfur (1-dodecyl mercaptan) has been verified to be an useful sulfur resource for the synthesis of unbelievely sized CdS quantum dots. Numerous magic dimension quantum dots (msqds) of different dimensions were effectively produced by regulating a few elements, consisting of families 378 and 407.
- 1-Dodecanethiol can be utilized to manufacture thiol secure metal nanoparticles (NPS), such as gold nanoparticles and silver nanoparticles, which have been generated as catalysts, digital gadgets, fillers, sensing units as well as energetic ingredients in composite products, in addition to other applications. As an example, silver nanoparticles prepared by borohydride reduction of silver nitrate are maintained by 1-dodecyl mercaptan which gives sulfur atoms in a two-phase system of water and also natural solvents (such as toluene, chloroform and also hexane). Various organic solvents play a major role in the bit dimension of silver nanoparticles. Because of this, it was located that the silver nanoparticles topped with 1-dodecyl mercaptan might work as a reliable stimulant to activate the decrease of 4-nitrophenol (4NP) in the presence of NaBH4.
- 1-Dodecanethiol can likewise be used to develop a stage transfer plan based upon 1-dodecyl mercaptan for effective removal of rare-earth element ions from the aqueous stage. First, a liquid service of metal ions is mixed with an ethanol solution of 1-dodecyl mercaptan, and then the sychronisation substance developed by rare-earth element ions and 1-dodecyl mercaptan is extracted right into a non-polar organic solvent. Several characterization strategies, including inductively combined plasma atomic discharge spectrometry (ICP-AES), Fourier transform infrared spectroscopy (FT-IR) as well as thermogravimetric evaluation (TGA), were utilized to define rare-earth element ions as well as 1-dodecyl mercaptan, and solved the complying with crucial problems: (1) move effectiveness of rare-earth element ions; (2) The transfer mechanism of this 1-dodecyl mercaptan based protocol; (3) The selectivity of this phase transfer system for removal of noble metal ions.
