摘要:
2,4,6-trifluoro-5-chloro-pyrimidine and the aqueous solution of a salt of 2-amino-5-aminomethyl-naphthalene-1-sulphonic acid are simultaneously metered into a reactor in approximately equimolar amounts and afford a valuable intermediate for the preparation of high-purity dyes.
摘要:
A process for the continuous reaction of halogenopyrimidines with amines, a halogenopyrimidine and an aqueous amine solution or suspension being passed into a reactor and the reaction product being subsequently conducted away, is described, characterized in that the starting materials are introduced into the reactor simultaneously and continuously with intensive mixing.
