Abstract:
     The invention relates to a process for inorganic sulfur content pesticide (solid stone sulphur synthetic agnet), which is divided into two steps. The first, at the pressure of 1-2 kgf/cm2, it undergoes boiling reaction 1-2 hours, then, filters out the impurity, the filtering liquid at the pressure 5-8 kgf/cm2 and the temperature 130-170 deg.C goes on catalytic reaction 2-4 hours. The catalytic agent contains silicon higher than 25% industrial waste material, its used quantity is 0.1-0.2%. Besides, at the enriched technique, it is to add 0.5-0.7% conjunction agent and anti-oxident. The method of this invention can heighten the quality and rate of recovery of the product, shorten the period of production, reduce the cost of product and heighten the stability of product-storage.
