Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
57 words
The use of a condensation reaction product of (1) a nonhindered phenol selected from the group consisting of: meta- cresol, para- cresol or a mixture of meta and para cresols, and (2) an aldehyde defined by R-CHO wherein R is hydrogen or an alkyl group having at least 1 carbon atom, as an antioxidant in organic compositions.
Claim 2
Dependent Claim
57 words
The use of a condensation reaction product of (1) a nonhindered phenol selected from the group consisting of: meta- cresol, para- cresol or a mixture of meta and para cresols, and (2) an aldehyde defined by R-CHO wherein R is hydrogen or an alkyl group having at least 1 carbon atom, as an antioxidant in organic compositions.
Claim 3
Dependent Claim
57 words
An organic composition containing an oxidation inhibiting amount of a condensation reaction product of (1) a nonhindered phenol selected from the group consisting of: meta- cresol, para- cresol or a mixture of meta and para cresols, and (2) an aldehyde defined by R-CHO wherein R is hydrogen or an alkyl group containing at least 1 carbon atom.
Claim 4
Dependent Claim
57 words
An organic composition containing an oxidation inhibiting amount of a condensation reaction product of (1) a nonhindered phenol selected from the group consisting of: meta- cresol, para- cresol or a mixture of meta and para cresols, and (2) an aldehyde defined by R-CHO wherein R is hydrogen or an alkyl group containing at least 1 carbon atom.
