light yellow transparent flammable liquid. The relative density was 1. 066. Freezing point 8 ℃. Density 1. 0425kg/L, flash point 226.7 ℃. Soluble in acetone and benzene, insoluble in water.
ethyl iodide is produced by the reaction of butanol with iodine and phosphorus. Iodoethane reacts with tin powder and magnesium powder to produce iodobutyltin, which is refined and treated with caustic soda to obtain dibutyltin oxide. Dibutyltin oxide and lauric acid are condensed at 60 °c to form dibutyltin laurate.
This product is PVC plastic additives, with excellent lubricity, transparency and weather resistance. Resistance to sulfide pollution is better, but the heat resistance is poor. It acts as a primary stabilizer in soft transparent articles and as a lubricant in hard transparent articles. This product is also used as a catalyst for the synthesis of polyurethane foam, silicone rubber curing agent.
This product is toxic. The maximum allowable concentration in air is 0.1 mg/m3. See dibutyltin oxide. Packed in tinplate barrels. Do not mix with acid, alkali, should be away from organic solvents. Protection against heat, moisture and sun. According to the provisions of toxic substances storage and transportation.
