| Hazard Information | Back Directory | [General Description]
Yellow to light orange-colored mass or yellow powder. | [Reactivity Profile]
METHYLENEBIS(THIOCYANATE)(6317-18-6) 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 . | [Air & Water Reactions]
May be sensitive to prolonged exposure to air. Decomposes in water (not vigorously) and more rapidly in boiling water. | [Fire Hazard]
Flash point data for this chemical are not available; however, METHYLENEBIS(THIOCYANATE) is probably combustible. | [Chemical Properties]
yellow crystalline powder | [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. |
