ABSTRACT:
Quaternary nitrogen-heterocyclic phosphonates wherein the phosphonate group is ortho- or para- to the nitrogen heterocyclic group, where the compounds are characterized as follows: ##STR1## wherein the dotted line represents a cyclic structure which cyclic structure may be the sole cyclic structure, or may be attached to other cyclic groups, where R is a hydrocarbon or a substituted hydrocarbon group such as alkyl, aryl, alkaryl, aralkyl, etc., and X is an anion such as halogen, a sulfite, a sulfate, a sulfonate-containing group, etc.
These nitrogen-heterocyclic phosphonates are prepared by reacting an aromatic nitrogen-heterocyclic compound, wherein the nitrogen atom is in the form of a quaternary alkoxy derivative (N--OR hereinafter defined) with a phosphite salt, preferably in the form of an ester of the phosphite, as exemplified by the following equation: ##STR2## Quaternaries of these compounds are prepared by further reaction with a quaternizing agent.
These compounds which may be characterized as quaternaries of phosphonates of nitrogen-heterocyclics have many uses including their use as biocides, such as bacteriocides, herbicides, corrosion inhibitors and chelating agents.
