Chemical Properties
White needle crystal. mp203°C. The solubility at 20°C is: methanol, ethanol 1%, acetone, ether 10%, dimethylformamide 18.2%, dimethyl sulfoxide 20%, insoluble in water. It is stable in the range of pH 2～10 and under heating and ultraviolet light irradiation, and can be hydrolyzed by boiling in 1mol/L hydrochloric acid for 6h.
Uses
Daimuron is a new substituted urea herbicides,it is absorbed by the roots of plants, which can significantly inhibit the elongation of roots and underground stems, so as to control the growth of the above-ground parts.It has special effects on sedge weeds, and can safely control the special-shaped weeds, triangular grasses, and cow hair grasses of crops such as rice, cotton, corn, soybeans, etc., with good results.
Definition
ChEBI: Daimuron is a member of ureas.
Synthesis
Synthesis of daimuron:Add 0.15 mol of p-tolylurea, 0.1 mol of cumene chloride, 48 g of α-methylstyrene and 160 g of acetonitrile, stir and react at 40°C for 6 hours, let stand at room temperature, separate 32 g of crystals, and yield 80%.
