yellowish liquid. Boiling Point (266. 6Pa)180 °c. The melting point was below -45 °c. The relative density was 1. 17. The flash point was greater than 100 °c. Viscosity (25 deg C) 4.8mPa.s. Practically insoluble in water and miscible with organic solvents. The compound formed by mixing with the material containing fiber and Wood is not easily decomposed. Or insoluble in water.
tin and chlorine are first synthesized as tin tetrachloride; N-Butanol is reacted with hydrochloric acid in the presence of zinc chloride to form chlorobutane; Metal magnesium is reacted with tin tetrachloride to form tributyltin chloride. With sodium hydroxide and then with the role of tributyltin chloride prepared by double tributyltin oxide, refined products.
This product is used for the synthesis of organic tin polymer resin, for the preparation of anticorrosive paint and pesticides, such as fumigant and fungicide.
