Abstract
Przedmiotem zgłoszenia jest sposób wytwarzania acetamiprydu w reakcji kondensacji N-metylo-2-chloro-5-pirydylometyloaminy i metylo- lub etylo- N-cyjanoacetamidyny. Reakcję kondensacji prowadzi się stosując w procesie jako rozpuszczalnik wodę lub mieszaninę woda-alkohol C1-C4 przy stosunku wagowym fazy wodnej do alkoholowej w zakresie od 10:1 do 1:10, w temperaturze pomiędzy 2°C a 40°C, a wydzielony produkt suszy się w temperaturze 40°C – 50°C. Wynalazek obejmuje także formę krystaliczną acetamiprydu.
