After loading Chlorella extinguish the vacuum with nitrogen, vklyuchayutsya 1.6 m3download 900 20 l of dimethylphosphite with transport vacuum. After downloading dimethylphosphite extinguish the vacuum with nitrogen and closed valving apparatus trying to enter the pressure within the 0.05-0.07 MPa.

When the temperature reached in the reactor 65-70oC steam in the jacket off. After this unit, start the dosage of dimethylphosphite in the reactor with a speed of 100 to 150 l/h, watching the rise of the temperature of the reaction mass in the reactor. When reaching into the reactor temperature 85-90oC supply dimethylphosphite in the reactor is stopped and the jacket serves the circulating water to remove excess heat of reaction. By reducing the temperature in the reactor up to 80-85oC dosage dimethylphosphite in the reactor resume and leading it with a speed of 200-300 l/h, maintaining the temperature in the reactor 90-95oC.

After the dosage of dimethylphosphite the flow of circulating water in the jacket of the reactor is stopped, the circulating water is drained from the jacket. The reaction mass in the reactor is maintained with stirring for 2.5 to 3.5 hours at a temperature of 90-95oC, maintaining the specified temperature of the steam in the jacket.

After the exposure time of the reaction mass in Reem supply of circulating water in the jacket of the reactor. Select a sample for analysis. Upon receipt of a positive result of the analysis in the reactor by means of the transport vacuum when operating the stirrer, and circulating cooling water load 35-45% dioxane from the reaction mass in the reactor. Mixing lead for another 30-40 minutes until complete dissolution of the liquid reaction mass of chlorophos in dioxanone.

One part of the concentrate is removed from the reactor, and by remaining in the reactor other part enter additional number dioxanone and receive pesticide tool in the following ingredients, wt.%:

The liquid reaction mass is an intermediate product of the interaction of chloral with dimethylphosphite and dioxanone when the ratio 1:(0,35-0,45) - 10,0-35,0

Dioxane - Rest

While stirring the liquid reaction mass of chlorophos with dioxanone carried out at a temperature of 45-50oC and atmospheric pressure for 0.5-1.0 hours

Further impose additional surfactant, for example, OP-7, permethrin and receive pesticide tool in the following ingredients, wt.%:
