- Continuous production method of multi-kettle serial triazine herbicide
-
The invention relates to a continuous production method of a multi-kettle serial triazine herbicide. A metered cyanuric chloride solution is pre-cooled and mixed with alkylamine R1 in a mixer to entera first-stage reaction kettle, continuous discharging is conducted, after a heat exchanger is passed, the cyanuric chloride solution is neutralized with alkali in the mixer and enters a first-stage neutralization kettle, after a reaction is completed, the cyanuric chloride solution passes through a continuous water separator and the heat exchanger and is mixed with alkylamine R2 in the mixer to enter a second-stage reaction kettle, the continuous discharging is conducted, after the cyanuric chloride solution passes through the heat exchanger, the cyanuric chloride solution is mixed with the alkali in the mixer to enter a second-stage neutralization kettle, after the neutralization, a aqueous phase is separated by a continuous layerer, a solvent is removed, and drying is conducted to obtain a triazine product. The production method has the advantages of high productivity, good production stability, high efficiency, high product quality and the like, is particularly suitable for technical transformation of existing production enterprises, has a low transformation cost, basically does not add novel reaction equipment, and is easily mastered by existing enterprises.

- ANTIFOULING COATING FILM WITH LOW FRICTIONAL RESISTANCE WITH WATER OR SEAWATER
-
The present invention provides an antifouling coating film, with reduced frictional resistance in water, that can reduce frictional resistance with seawater in locations in which friction with seawater occurs, such as ships and conduits. The present invention provides an antifouling coating film that has a low frictional resistance with water or seawater, comprises an antifoulant in a coating film composed of a polymer hydrogel, and is characterized in that the antifouling film has a degree of swelling of 10-80% and a Young's modulus of 500-30,000 N/cm2; also provided is an antifouling coating composition for forming such an antifouling film.

- Evaluation and Optimisation of the Reagent Addition Sequence during the Synthesis of Atrazine (6-Chloro-N2-ethyl-N4-isopropyl-1,3, 5-triazine-2,4-diamine) Using Reaction Calorimetry
-
The sequence of reagent addition and associated heats of reaction during the synthesis of the important herbicide atrazine (6-chloro-N 2-ethyl-N4-isopropyl-1,3,5-triazine-2,4-diamine) from cyanuric chloride, isopropylamine, and ethylamine have been investigated by means of calorimetric and analytical methods. Sodium hydroxide was used as proton scavenger in this procedure. The best addition sequence found was the concurrent addition of amine and NaOH, keeping the amine in slight excess at all times. Using this feed sequence, the reaction becomes feed-controlled, and provided that a proper level of mixing can be maintained in the reactor, a high degree of control over reaction selectivity is obtained.

- Pesticide-polymer systems prepared from vinyl monomers
-
Controlled release pesticide-polymer systems are prepared by the polymerization of vinyl monomers containing pendant pesticides. The vinyl monomers are prepared by reacting an acrylic acid derivative with a pesticide or a pesticide derivative having an active hydrogen. The pesticide-polymer systems prepared from the pesticide vinyl monomers release the active pesticide material by hydrolysis or chemical depolymerization under conditions of use.

2-CHLORO-S-TRIAZINE SUBSTITUTED IN AT LEAST ONE OF THE POSITIONS 4,6 OF THE TRIAZINE RING WITH AN AMINO GROUP IS OBTAINED BY FEEDING SEPARATELY AN AQUEOUS AMINE SOLUTION AND AN AQUEOUS NaOH solution into a water-organic liquid reaction medium containing cyanuric chloride, delivering to said medium per unit of time from 1.05 to 1.30 moles of amine for each mole of sodium hydroxide, feeding the amine solution until an amount of from 1 to 2 moles of amine per mole of cyanuric chloride is reached in the medium and the NaOH solution until an amount in moles equal to or slightly higher than the amount of amine moles fed in is reached in the medium. The temperature of the reaction medium is maintained at a value of from 5°-15° C to 60°-70° C during the feeding period.
