Title:
METHOD FOR MEASURING DIAZOTIZATION RATE OF AROMATIC AMINO COMPOUND
Document Type and Number:
Japanese Patent JPH03107761
Kind Code:
A
Abstract:
PURPOSE: To more explicitly and quantitatively recognize reaction by measuring the diazotization rate from the quantity of the phenol formed by hydrolyzing a diazonium salt.
CONSTITUTION: The diazonium salt is formed by bringing an amino compd. into reaction with a diazotizing agent in the presence of hydrofluoric acid. This diazonium salt is hydrolyzed to quantitatively form the phenol. The diazotization rate is, therefore, measured by determining the phenol formed by the hydrolysis.
