Physical and Chemical Properties	The scientific name of Green Gulong is 3-(4-chlorophenyl)-1-methoxy-1-methylurea, the common name is monolinuron. White odorless crystal, melting point 79-80 ℃. The solubility in room temperature water is 0.58g/L, soluble in acetone, ethanol and mixed xylene. It is stable at its melting point temperature and in aqueous solution; it decomposes slowly in acids and alkalis, and in moist soil. Non-corrosive. It is prepared by the reaction of 4-chlorophenyl isocyanate with hydroxylamine, and then with dimethyl sulfate. It is a pre-bud herbicide, which can be absorbed by leaves and roots, and can effectively control annual weeds.
