Isocyanate, sodium Isothiocyanate, Thiocyanic Acid, Sodium Salt
Properties: NaSCN,a white rhombic system crystal, is soluble in water, ethanol, acetone; Relative density is 1.735. Melts at approx.287°C. decomposes on heating and under influence of light producing toxic fumes of sulfur oxides,nitrogen
oxides and cyanides. Reacts violently with acids,strong bases and strong oxidants.
Usage:
Genaral: Mainly used in sectors of pharmaceuticals, pesticide, synthetic fibre, electroplating, photography, accelerator for cement etc
Fibre industriy :as spinning solvent for polyacrylonitrile
Architecture industriy:hardening accelerator for cement and concrete mixes
Pesticide: raw material for the production of a number of herbicides and fungicides
Pharmaceuticals: raw material for the production of a number of pharmaceutical products
Packing: 25 kgs net in PP bag with inner of polyethylene bag.
Storage: Keep in tightly closed bags.Store in cool, dry, ventilated area to prevent it from being deliquescent. Separated
from acides, bases and oxidants.
