white or off-white powder. The relative density was 2. 846. Melting point 1084 °c. Almost insoluble in water, difficult to dissolve in dilute hydrochloric acid, ethanol, acetone, soluble in ammonia and ether, soluble in concentrated alkali metal thiocyanate solution, can form a complex. Dissolved in concentrated sulfuric acid is decomposed.
In the air heated to more than 140 deg C can fire combustion. The dried cuprous thiocyanate absorbs ammonia on cooling to form an adduct containing cuprous thiocyanate (2cuscn. 5nh3), which releases ammonia upon heating.
sulfite reduction method copper sulfate is reduced with sodium sulfite under alkaline conditions, and then reacted with sodium thiocyanate to form a white precipitate, which is filtered, washed with water and dried to obtain cuprous thiocyanate.
is an excellent inorganic pigment, used as Ship Bottom antifouling paint, its stability is better than cuprous oxide. Compounding with organotin compounds is an effective antifouling agent. With bactericidal (mildew) and insecticidal activity, for fruit protection. It is used as flame retardant and smoke suppressant for polyvinyl chloride plastics with the addition amount of 0. 01% ~ 10% of the resin. It is used as smoke suppressant in combination with nickel sulfate or melamine molybdate, and used as flame retardant and smoke suppressant in combination with halogenated unsaturated polyester resin. It is used as an additive for lubricating oil and grease, non-silver salt photosensitive material, organic synthesis catalyst or polymerization reaction regulator, copper plating agent, electrode material for seawater battery, and stabilizer for Polysulfide rubber, glass fiber dyeing carrier and tooth abrasive.
packed in a dry plastic drum or plywood drum lined with a polyethylene plastic bag, 25kg net weight per barrel, 40kg. Should be stored in a ventilated, dry place, pay attention to moisture, do not pressure, to prevent the lid and broken barrels. The packaging must be sealed. It is not allowed to be stored and mixed with acid and edible articles. Transport should be protected from rain and sun. Fire can be suppressed with water and sand. Toxicity and protection: see sodium thiocyanate.
