Paragraph 0110; 0115-0119, (2019/05/04)
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.

, (2008/06/13)
Flowable herbicidal compositions which contain an active component combination of at least one triazine and at least one chloroacetanilide with a surfactant component. This surfactant component, which consists of an anionic compound based on a monosulfuric acid ester of alkyl or alkyphenol polyglycol ethers as well as at least one nonionic alkyl or alkylphenol polyglycol ether, gives stable dispersions of the concentrated composition and forms stable dispersions of dilutions of the compositions suitable for direct use.

, (2008/06/13)
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.
