About this document
Synthesis and Properties of Sudan I Dye by Chino Bandonil is a document available to read on EtoBox.
1. The document summarizes the synthesis of the red dye Sudan I (1-phenylazo-2-naphthol) through a diazo coupling reaction between phenyldiazonium chloride and β-naphthol. 2.97 grams of Sudan I dye was produced, with a melting point between 129°C -132 °C. 2. The reaction involves preparing phenyldiazonium chloride from aniline through diazotization, and deprotonating β-naphthol in basic conditions. Mixing the reagents results in an electrophilic aromatic substitution reaction to form the azo-linked dye. 3
