Description
Vynálezom je suspenzný koncentrát 2-izopropylamíno-4-etylamíno-6~chlór-s-triazínu obsahujúci až 55 % hmotnostných účinnej látky atrazínu.The invention is a suspension concentrate of 2-isopropylamino-4-ethylamino-6-chloro-s-triazine containing up to 55% by weight of the active ingredient atrazine.
Medzi najznámejšie a najviac vyrábané s-triazínové herbicidy patří 2-izopropylamíno-3-etylamíno-5-chlór-s.-triazín (atrazín). Herbicídne účinky bolí objavené v roku 1954 vo Svajčiarsku a sú popísáné vo švajčiarskom patente 229 227. Příprava atrazínu reakciou kyanurchloridu, etylamínu, izopropylaminu a hydroxidu sodného vo vodnochlórbenzénovom prostředí je popísaná v Československem patente 110 352.Příprava atrazínu reakciou kyanurchloridu a etylamínu, izopropylamínu v prostředí bezvedného organického rozpúštadla, pričom na viazanie vzniklého chlorovodíka sa použije bezvodného amoniaku, popisuje švajčiarsky patent 508 640. Získaný produkt obsahuje 92 % atrazínu. Vplyv hodnoty pH na výtažek atrazínu popisujú patentové spisy NDR a NSR. Podia NDR patentu 51 646 sa najlepší výtažek dosiahne vtedy, ak v prvom reakčnom stupni, t.j. po přidaní prvého aminu a hydroxidu alkalického kovu sa udržuje hodnota pH 6 až 8, v druhem reakčnom stupni, t.j. po přidaní druhého aminu a hydroxidu alkalického kovu, sa udržuje hodnota pH na 8,5 až 9. Výtažok atrazínu je 96 %. V NSR patente 2 032 861 sa udává hodnota pH v prvom stupni 6,5 až 10. V USA patente 3 328 399 a 3 586 679 je popísaný spósob přípravy atrazínu z kyanurchloridu, etylamínu, izopropylamínu v bezvodnom prostředí pri teplote 120 - 170 °C za oddestilovania vzniknutého chlorovodíka. Výhoda sposobu je, že odpadne problém odpadných vod s obsahem minerálnych solí. Vo švajčarskom patente 546 247 sa popisuje adiabatický spásob výroby atrazínu vo vodonerozpustnom rozpúštadle reakciou etylamínu, izopropylamínu, alkalického hydroxidu s kyanurchloridom.Vo francúzskom patente 2 296 628, rumunskom patente 68 016, japonskom patente 131 592 (1977) sa doporučuje pri dávkovaní amínov pri výrobě atrazínu dávkovat prvý izopropylamín. Bank. C. a spol. J. Am. Chem. Soc. 66 1771 (1944) a Pridheim E., J. Am. Chem. Soc. 66 1725 (1944) doporučujú pri prvom reakčnom stupni výroby atrazínu teplotu okolo O °C a druhý reakčný stupeň pri teplotách 30 - 50 °C. Pri prvom reakčnom stupni sa ako reakčné prostredie používá zmes vody a ladu, připadne voda, lad a organické rozpúštadlo.The best known and most widely produced s-triazine herbicides include 2-isopropylamino-3-ethylamino-5-chloro-s.-triazine (atrazine). Herbicidal effects were discovered in 1954 in Switzerland and are described in Swiss patent 229 227. The preparation of atrazine by the reaction of cyanuric chloride, ethylamine, isopropylamine and sodium hydroxide in aqueous chlorobenzene medium is described in Czechoslovak patent 110 352. The preparation of atrazine by the reaction of ethylamloride Anhydrous organic solvent, using anhydrous ammonia to bind the resulting hydrogen chloride, is described in Swiss Patent 508,640. The product obtained contains 92% of atrazine. The effect of pH on atrazine yield is described in the GDR and NSR patents. According to GDR patent 51 646, the best yield is obtained if in the first reaction step, i. after the addition of the first amine and the alkali metal hydroxide, the pH is maintained at 6 to 8, in the second reaction step, i. after the addition of the second amine and the alkali metal hydroxide, the pH is maintained at 8.5 to 9. The yield of atrazine is 96%. U.S. Pat. No. 2,032,861 discloses a pH of 6.5 to 10 in the first stage. U.S. Pat. Nos. 3,328,399 and 3,586,679 describe a process for preparing atrazine from cyanuric chloride, ethylamine, isopropylamine in an anhydrous medium at 120-170 ° C. distilling off the hydrogen chloride formed. The advantage of this method is that the problem of wastewater containing mineral salts is eliminated. Swiss Patent 546,247 describes an adiabatic process for the production of atrazine in a water-insoluble solvent by the reaction of ethylamine, isopropylamine, alkali hydroxide with cyanuric chloride. atrazine dosed with the first isopropylamine. Bank. C. et al. J. Am. Chem. Soc. 66 1771 (1944) and Pridheim E., J. Am. Chem. Soc. 66 1725 (1944) recommend a temperature of about 0 ° C in the first reaction step for the production of atrazine and a temperature of about 30-50 ° C in the second reaction step. In the first reaction step, a mixture of water and ice or water, ice and an organic solvent is used as the reaction medium.
