Compounds which are the reaction products of a C.sub.12-14 -alkyl N-substituted 1,3-diaminopropane and glutamic acid or its 5-methyl ester, optionally alkoxylated, and optionally their salts, are useful as antimicrobial agents.

N-substituted diaminopropane/glutamic acid reaction products

This invention is directed to novel antimicrobial agents. More particularly, this invention is directed to 2-(3-iodo-2-propynyloxy)-ethyl carbamates of the formula ##STR1## wherein R is hydrogen, linear or branched alkyl of from 1 to 12 carbon atoms, cycloalkyl of from 4 to 8 carbon atoms, aryl, substituted aryl, aralkyl, or arylsulfonyl;

2-(3-Iodo-2-propynyloxy)-ethyl carbamates, the preparation thereof, and

A method for inhibiting corrosion of nonferrous metals in contact with circulating water comprising the steps of adding to circulating water in contact with non-ferrrous metals from 0.05 to 10 gm/m.sup.3 of at least one 3-amino-5-alkyl-1,2,4-triazole wherein said alkyl has from 2 to 8 carbon atoms and adjusting said water to a pH of from 6 to 10; as well as corrosion inhibiting compositions containing said 3-amino-5-alkyl-1,2,4-triazole.
