Abstract
Dihydro-nitrogen heterocyclic phosphoramidates of the general formula ##EQU1## where N--C represents a dihydro-nitrogen ring, R is a substituted group, preferably hydrocarbon, X is O or S, and R.sub.1 is an alcohol or phenolic moiety, preferably hydrocarbon; the preparation and uses thereof particularly as corrosion inhibitors, microbiocides, etc.
Claims12
A process of inhibiting the growth of bacteria, fungi, algae and protozoa in an aqueous or petroleum hydrocarbon system which comprises adding to said system an effective amount of a Diels-Alder Adduct of (1) a dihydro-nitrogen phosphoramidate of the formula ##EQU7## where N -- C represents a nitrogen heterocyclic group, R and R.sub.1 are lower alkyl or phenyl and X is O or S, and (2) a dienophile selected from the group consisting of unsaturated acids, alpha, beta-unsaturated carbonyl compounds, acetylenic compounds and cyclic ketones.
The process of preventing or inhibiting the growth of bacteria in an aqueous or petroleum hydrocarbon system which comprises adding to said system a Diels-Alder Adduct of the formula ##SPC19##
- in an amount sufficient to prevent or inhibit the growth of bacteria in said system.
