1-Chloro-2-methoxy-3-nitrobenzene Use and Manufacturing
To the four-necked flask were added 2, 3-dichloronitrobenzene 488 (0.2511101), methanol 1928, diisopropylamine25g (0.25mol), heated to 60 ° C, dropping 28percent NaOCH 396. 4g (0.5mol), the insulation for etherification reaction 5h after sampling in the control. Remove the solvent, add water, 200g slurry washing solids, filter out the solid, add water to wash the filter cake, vacuum drying, in compound Π41.46g, etherification reaction yield 85percent, purity 95percent. 39.9 g of compound II was weighed into a 500 mL autoclave, and then 0.4 g of 1percent platinum carbon was added, 120 g of methanol was added and the temperature was raised to 40 ° C and the pressure was 0.4 MPa. Time 18h, sampling control. After filtering off the catalyst, methanol was removed and 3-chloroanisidine 32 was precipitated. The yield was 96percent, purity> 93percent, and the total yield was 81.6percent.
