Structure of Naphthol Modified Urea-Formaldehyde Resins by Using The Method of Nuclear Magnetic Resonance.

摘要

ABSTRACT The scale of phenol consumption is significant but to meet the industry needs not only phenol is necessary but naphthols and different phenol homologs are important either. Both naphthols ( - and -type) have a great technical significance; -naphthol is the most important one among the simple intermediate products of a naphthalene number. Naphthols are used in the manufacture of azo -dyes as azocomponents and they are the initial products for producing of naphtholsulfoacids which a.
