Abstract
Abstract A method for inhibiting the atmospheric corrosion of metals in a sealed space with inhibiting amounts of vapor phase inhibitors consisting of disposing in said sealed space a carrier means for storing a stock of inhibitors and diffusing their vapors wherein said carrier means is silica gel or zeolite and contains a liquid inhibitor selected from the group consisting of primary, secondary and tertiary amines and mixtures thereof.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
66 words
A method for inhibiting the atmospheric corrosion of metals in a sealed space with a corrosion-inhibiting amount of vapor phase inhibitors consisting of disposing in said sealed space a carrier means for diffusing the vapors of said inhibitors, said carrier means consisting of zeolites, and said carrier means containing a liquid inhibitor selected from the group consisting of primary, secondary and tertiary amines, and mixtures thereof.
Claim 2
Independent Claim
66 words
A method for inhibiting the atmospheric corrosion of metals in a sealed space with a corrosion-inhibiting amount of vapor phase inhibitors consisting of disposing in said sealed space a carrier means for diffusing the vapors of said inhibitors, said carrier means consisting of zeolites, and said carrier means containing a liquid inhibitor selected from the group consisting of primary, secondary and tertiary amines, and mixtures thereof.
Claim 3
Dependent Claim
35 words
A method as claimed in claim 1 wherein the amount of the said porous carrier means plus said vapor phase inhibitor constitutes from 10 to 100 g per 1 m 3 of the sealed space.
Claim 4
Dependent Claim
31 words
A method as claimed in claim 1 wherein the amount of the vapor phase inhibitor constitutes from 0.01 g to 1 g per 1 g of the said porous carrier means.
Claim 5
Dependent Claim
35 words
A method as claimed in claim 3 wherein the amount of the said porous carrier means plus said vapor phase inhibitor constitutes from 10 to 100 g per 1 m 3 of the sealed space.
Claim 6
Dependent Claim
28 words
A method as claimed in claim 1 wherein said carrier means consists of zeolites having pores with a diameter in the range of from 4 to 15 A.
Claim 7
Dependent Claim
31 words
A method as claimed in claim 5 wherein the amount of the vapor phase inhibitor constitutes from 0.01 g to 1 g per 1 g of the said porous carrier means.
Claim 8
Dependent Claim
36 words
A method as claimed in claim 6 wherein the amount of the said porous carrier means plus said vapor phase inhibitor constitutes from 10 g to 100 g per 1 m 3 of the sealed space.
