| | Methylene dithiocyanate Usage And Synthesis |
| Chemical Properties | Colorless needle-like crystals or yellow crystalline powder. Melting point 102-104 ℃. Soluble in dioxane, dimethylformamide, slightly soluble in other organic solvents. The solubility in room temperature water is 2300 ppm. It is very sensitive to pH, and hydrolyzes quickly above pH=8. | | Uses | Methylene Dithiocyanate emulsion is used as bactericide. | | Preparation | Synthesis of methylene dithiocyanate: under pressure, add excess sodium thiocyanate (or sodium thiocyanate) and dichloromethane into the reaction kettle, start stirring, and heat up to 80-100°C at the same time. After the reaction is completed, dichloromethane is recovered, and the solid-liquid two phases are separated to obtain a crude methylene dithiocyanate. | | Definition | ChEBI: Methylene dithiocyanate is a member of the class of thiocyanates that is methane in which two of the hycrogens have been replaced by thiocyanato groups. Used as a biocide for the control of various pathogens and algae in industrial water systems and as a fungicide for the control of surface moulds and sapstain fungi on wood. It has a role as a fungicide and an antibacterial agent. | | General Description | Methylenebis(thiocyanate) appears as yellow to light orange-colored mass or yellow powder. (NTP, 1992) | | Air & Water Reactions | May be sensitive to prolonged exposure to air. Decomposes in water (not vigorously) and more rapidly in boiling water. | | Reactivity Profile | Methylenedithiocyanate reacts vigorously with strong bases and strong oxidizing agents such as hydrogen peroxide. Hydrolyzes slowly with water at boiling temperatures and reacts slowly and exothermically with aqueous acids . | | Fire Hazard | Flash point data for Methylenedithiocyanate are not available; however, Methylenedithiocyanate is probably combustible. | | Safety Profile | Poison by ingestion,
intravenous, and subcutaneous routes.
When heated to decomposition it emits very
toxic fumes of NOx and SOx. |
