化學的特性
1-Dodecanethiol is a colourless liquid organic compound, with a characteristic odour. Soluble in methanol, ether, acetone, benzene, ethyl acetate, insoluble in water.
製造方法
Preparation of 1-dodecanethiol: 1-Bromododecane, thiourea and 95% ethanol are heated to reflux reaction, then sodium hydroxide solution is added and heated. After the reaction is finished, cooled and left to stratify, the oil layer is the crude thiol. The crude product is washed with water, dried, distilled, and distilled under reduced pressure, which is 1-dodecanethiol.
主な応用
1-Dodecanethiol (DDT) can be used as a source of sulfur for the synthesis CdS quantum dots (QDs) and lead sulfide nanoparticles (PbS) which find potential applications in energy efficient lighting, solar cells and as ammonium gas sensing agents. DDT may be used to form a self-assembled monolayer (SAM) on copper surface as a corrosion resistant coating. Functionalization with DDT may form SAMs on geranium (Ge) to improve the surface characteristics for futuristic applications in microelectronics. This molecule is used for the production of hydrophobic SAMs. It can also be used in mixed SAMs to give a hydrophobic background and act as a spacer to move other functional groups or domains farther apart.
説明
1-Dodecanethiol is a kind of oily colorless liquid with a mild skunk odor. It is used in the preparation of hydrophobic or mixed self-assembled monolayers.
空気と水の反応
Air and moisture sensitive. Insoluble in water. Reacts vigorously with water or steam.
反応プロフィール
1-Dodecanethiol is incompatible with bases, oxidizing agents, reducing agents and alkali metals. Easily oxidized to disulfide.
健康ハザード
1-Dodecanethiol is irritating to skin, eyes, and mucous membranes. Ingestion may cause nausea. Repeated skin exposure can cause dermatitis and may produce a sensitizing effect. It is very toxic to aquatic life with long lasting effects.
火災危険
Special Hazards of Combustion Products: Poisonous and irritating gases (e.g., sulfur dioxide) are generated in fires.
純化方法
Dry it with CaO for several days, then distil it from CaO. [Beilstein 1 IV 1851.]
