Uses and applications

What the substance is used for, by industry and function

Methoprotryne is herbicide used post emergence for the control of weed grasses in winter-sown cereals at 1.5-2.0 kg active ingredient/hectare.

Methoprotryne is herbicide used in combination with simazine post emergence for the control of weed grasses in winter sown cereals at 2.5-4.0 kg gesaran 2079/ha.

Use classes: Herbicides, Pharmaceuticals.

How it is made

React 2-chlor-4-isopropylamino-6-(3-methoxypropylamino)-1,3,5-triazine with methyl mercaptan in the presence of an equivalent of alkali or react 2-isopropylamino-4-mercapto-6-(3-methoxypropylamino)-1,3,5-triazine with a methylating agent in the presence of alkali.

46 parts of cyanuric chloride are dissolved in 300 parts of chlorobenzene. Then, at -15 °C to -5 °C, first 14 parts of isopropylamine dissolved in 22 parts of water and then 10 parts of sodium hydroxide dissolved in 40 parts of water are added dropwise.

The whole is stirred until the reaction mixture has a neutral reaction, any traces of precipitated 2-chloro-4,6-bis-isopropylamino-s-triazine are removed and then, at room temp, 23 parts of gamma-methyoxy-propylamine in 46 parts of water and afterwards 10 parts of sodium hydroxide in 40 parts of water are added. The whole is stirred at 40 °C to 50 °C until the reaction mixture has a neutral reaction. The chlorobenzene is eliminated by steam distillation whereupon the difficultly soluble 2-chloro-4-isopropylamino-6-(gamma-methosy-propylamino)-s-triazine can be filtered off under suction and recrystallized. 26 parts of 2-chloro-4-isopropylamino-6-(gamma-methoxy-propylamino)-s-triazine are mixed with 100 ml of concentrated aq potassium hydrosulfide soln and stirred until a practically clear soln is obtained.
