DEFINITION

Classification: 544/107

(under subclass 106) Compounds which are acid addition salts

of (a) unsubstituted morpholine, or (b) morpholine substituted by hydrocarbon radicals only.

(1) Note. Examples of compounds provided for herein are: [figure] [figure]

(2) Note. The substituents attached to the morpholine ring by nonionic bonding must contain only hydrogen and carbon.
