ABSTRACT:
This invention relates to the reduction of THP to perhydrophenanthridines (PHA) with formic acid. This is illustrated by the following equation ##STR1## where R is hydrogen or a substituted group, such as hydrocarbon, for example alkyl, etc.; and X and Y are hydrogen or a substituted group, such as a hydrocarbon group containing a functional group, for example alkyl-X where X is a functional group such as nitrilo, carboxyl, etc. The perhydrophenanthridines of this invention are useful as corrosion inhibitors and as fuel stability additives.
