DEFINITION

Classification: 508/542

Compound of indeterminate structure, prepared by reacting an aldehyde, a phenol or phenol salt, and ammonia or substituted ammonia (e.g., reaction of formaldehyde, phenol, and amine, etc.):

(under subclass 110) Compositions which contain a compound of indeterminate structure which is prepared by reacting (1) ammonia or substituted ammonia, (2) a phenol or a phenol salt, and (3) an aldehyde.

(1) Note. Many of the compounds of indeterminate structure provided for as components herein are the class of compounds known as Mannich bases. Many compounds which result from this type reaction, however, are of known structure. In this class, subclasses 556+ provide for many compounds of this type.
