C.I.酸性红111的合成研究

The Research on the Synthesis of C. I. Acid Red 111

本文研究了以 Ｈ－酸脱氮合成 １－萘酚－３， ６－二磺酸，制Ｃ．Ｉ．酸性红 １１１，提高产品质量及收率，降低成本。

From the researching of the synthesis of the 1-naphthol - 3, 6-disulfonic acid and the C. I. Acid Red 111 which is synthesized by the denitrification of the H-acid, we get the better quality and the higher yield of the product, meanwhile we also use lower cost.
