NAPROPAMIDE - Uses and synthesis methods
overview
dioxalamine, chemical name N,N-diethyl-2-(α-naphthoxy) propanamide, there is a chiral carbon in the molecule, so there is a pair of enantiomers. It is an amide selective pre-budding soil treatment herbicide used to control annual gramineous weeds and some dicotyledonous weeds during the budding period.
application
dioxalamine is an amide selective pre-bud soil treatment herbicide, which is used to control annual gramineous weeds and some dicotyledonous weeds during the germination period.
Toxicity
acute oral LD504680mg/kg (male) and> 5000 mg/kg (female) of industrial products on rats; Rabbit acute percutaneous LD50>5000 mg/kg, rat inhalation LC50>6.22mg/L. Slight irritation to eyes and skin. No carcinogenic, teratogenic and mutagenic effects. There was no abnormality in the three-generation reproduction test. Blue gill LC5012.2mg/L (96h), Daphnia LC5014.3mg/L, quail oral LD50>5620mg/kg.
Production method
1. React α-chloropropionic acid with phosgene to form α-chloropropionyl chloride, then react with diethylamine to form α-chloropropionyl diamine, and finally condensed with 1-naphthol to obtain dioxalamine.
2, α-naphthol and N, N-diethyl-2-chloropropanamide are prepared.
