Methylene dithiocyanate CAS 6317-18-6 Water Purification Chemicals
Dithiocyanomethane is also known as methyl dithiocyanate, immersed seed Ling, methylene dithiocyanate, or MBT for short. Light yellow or nearly colorless needle like crystal. Molecular weight 130.2, relative density (20 ℃) 1.1 ± 0.1, m.p.102-104 ℃, flash point 53 ℃. It is almost insoluble in water and its solubility in room temperature water is 2.3 × 10-6. Therefore, when using, we usually need to add some special dispersant and penetrant chemical book. Soluble in dioxane, dimethylformamide, etc., slightly soluble in other organic solvents. MBT is stable in the range of ph6-6.5, but hydrolyzes rapidly at pH 8. Under pressure, excess sodium thiocyanate (or sodium thiocyanate) and dichloromethane are added to the reactor, stirred, and heated to 80-100 ℃. After the reaction, dichloromethane is recovered and the solid-liquid two phases are separated to obtain the crude product of thiocyanomethane.
