Water resistant aluminum particles and coating

Claim 1

A composition of matter which comprises metal particles which include compound of the formulae of FIGS. 1A, 1B or 1C in an effective concentration to retard the reaction of the metal with water, thereby inhibiting the evolution of hydrogen gas, where in said formulae, X=1 or 2, Y=1 or 2, and X+Y=3; where Z is hydrogen or means for neutralizing acid phosphate; and where R is benzo, a halo group, an alkyl group having from 1 to 24 carbon atoms, a cycloalkyl group having from 3 to 20 carbon atoms, an aryl group having from 6 to 40 carbon atoms, a halo substituted aryl group wherein said aryl has from 6 to 40 carbon atoms, an alpha or beta naphthyl, a halo substituted alpha or beta naphthyl, a 3 to 20 carbon atom cycloalkyl substituted alpha or beta naphthyl, an alpha or beta alkyl substituted naphthyl wherein said alkyl has from 1 to 24 carbon atoms, a heterosubstituent substituted aryl wherein said aryl has from 6 to 40 carbon atoms, and said heterosubstituent is selected from the group consisting of CN, NO 2 , COOH, CHO, OH, a pyridinyl, an alpha or beta furyl, or an alpha or beta thienyl.

Claim 9

A method which comprises contacting metal particles with compound of the formulae of FIGS. 1A, 1B or 1C in an effective concentration to retard the reaction of the metal with water, thereby inhibiting the evolution of hydrogen gas, where in said formulae, X=1 or 2, Y=1 or 2, and X+Y=3; where Z is hydrogen or means for neutralizing acid phosphate; and where R is benzo, a halo group, an alkyl group having from 1 to 24 carbon atoms, a cycloalkyl group having from 3 to 20 carbon atoms, an aryl group having from 6 to 40 carbon atoms, a halo substituted aryl group wherein said aryl has from 6 to 40 carbon atoms, an alpha or beta naphthyl, a halo substituted alpha or beta naphthyl, a 3 to 20 carbon atom cycloalkyl substituted alpha or beta naphthyl, an alpha or beta alkyl substituted naphthyl wherein said alkyl has from 1 to 24 carbon atoms, a heterosubstituent substituted aryl wherein said aryl has from 6 to 40 carbon atoms, and said heterosubstituent is selected from the group consisting of CN, NO 2 , COOH, CHO, OH, a pyridinyl, an alpha or beta furyl, or an alpha or beta thienyl.

Claim 10

A method which comprises contacting metal particles with compound of the formulae of FIGS. 1A, 1B or 1C in an effective concentration to retard the reaction of the metal with water, thereby inhibiting the evolution of hydrogen gas, where in said formulae, X=1 or 2, Y=1 or 2, and X+Y=3; where Z is hydrogen or means for neutralizing acid phosphate; and where R is benzo, a halo group, an alkyl group having from 1 to 24 carbon atoms, a cycloalkyl group having from 3 to 20 carbon atoms, an aryl group having from 6 to 40 carbon atoms, a halo substituted aryl group wherein said aryl has from 6 to 40 carbon atoms, an alpha or beta naphthyl, a halo substituted alpha or beta naphthyl, a 3 to 20 carbon atom cycloalkyl substituted alpha or beta naphthyl, an alpha or beta alkyl substituted naphthyl wherein said alkyl has from 1 to 24 carbon atoms, a heterosubstituent substituted aryl wherein said aryl has from 6 to 40 carbon atoms, and said heterosubstituent is selected from the group consisting of CN, NO 2 , COOH, CHO, OH, a pyridinyl, an alpha or beta furyl, or an alpha or beta thienyl.
