- W2348351637 abstract "Chloroacetyl chloride was synthesized from monochloroacetic acid and thionyl dichoride by conventional method.Then,2-chloro-N-(4-hydroxyphenyl) acetamide was synthesized in a mixed solvent composed of chloroethane and ethyl acetate by the reaction of carbonyl chlorinating agent-chloroacetyl chloride with 4-aminophenol.The product yield was more than 90% in chloroethane solvent.Moreover,effects of reaction conditions on the product yield were discussed.The optimum preparation conditions were obtained by orthogonal experiments as follows:a ratio of n(4-aminophenol)∶n(chloroacetyl chloride)∶n(solvent)=1∶2.5∶9,a reaction temperature of 80 ℃,and a reaction time of 3 h.The structure of target product was verified by means of EA,mass spectrometry,IR and 1HNMR spectroscopy." @default.
