摘要
以工业品对氨基苯甲酸为原料,经重氮化、碘代合成对碘苯甲酸,纯度99.9%,总收率97.9%,m.p.:265～266℃。产物结构经IR和1HNMR确证。
The 4-iodobenzoic acid was synthesized from 4-aminobenzoic acid by diazotization and iodination with 97.9% of the yield of the pwdnot and melting point of 265-266℃ o The structures of the product was confirmed by IR and ^1H NMR.
