SYNTHESIS AND FORMULATION OF PESTICIDES B ASED ON N-PHOSPHONOMETHYLGLYCINE

The genuine method of N-phosphonmethylglicyne (FMG) synthesis from gli cyne, triethylphosphite and formaldehyde was developed and patented by the IPO (Institute of Industrial Organic Chemistry). FMG formes after the acidic hydrolysis of sodium N-diethylphosphonmethylglicate, obtai ned as the result of a two stage synthesis in the contineous two react or cascade. The compound is used as an active substance in numerous pe sticides. Two dimensional mathematical model describing reaction yield versus time was developed to calculate presented optimum synthesis co nditions. On the base of this method, the pilot plant has been built a t the IPO. Synthesis of intermediate product is a continous process, a ll others are batch ones. The plant capacity amounts 100 kg FMG per ba tch. The technology of new herbicides - Perzocyd 220SL and 280SL has a lso been developed.
