Green nitration
WebMar 1, 2014 · While the nitration of chlorobenzene was much slower than that of benzene, but the yield was higher and the ratio of para/ortho isomer was about 3. N.L Lancaster [17] studied several nitration systems on aromatic nitration using methylimidazolium-based ionic liquids as the catalysts, and they demonstrated that HNO 3 /Ac 2 O was the best ... WebFOR THE LAD REPORT DISCUSSION SECTION Discuss the mechanism of the green nitration of 4-hydroxyphenylacetic acid; include the full arrow-pushing mechanism to illustrate. Make sure to address the expected regioselectivity of the reaction. Discuss your percent yield and, if it's low, give reasons for loss of material.
