- Synthesis method of solvent yellow 124
-
The invention discloses a synthesis method of solvent yellow 124. The synthesis method comprises the following steps: diazotizing aniline serving as a raw material to obtain chloridized diazonium benzene, carrying out reaction on N-ethyl-N-hydroxyethylaniline and treated metal sodium particles to obtain sodium alcoholate, carrying out aldolization on the sodium alcoholate, and carrying out coupling reaction on the sodium alcoholate subjected to the aldolization and the chloridized diazonium benzene to obtain the solvent yellow 124. The reaction line is high in synthesis yield, and a prepared product is high in purity and contains few impurities; meanwhile, the reaction conditions are mild, and a middle body is high in purity and stable; continuous or intermittent operation can be performed; a technical support is supplied to industrial continuous production.
