Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
29 words
The process of claim 1 wherein the alkyl phenol compound is a phenol containing one (1) alkyl group, said phenol ranging in molecular weight from about 149 to 460.
Claim 2
Dependent Claim
27 words
The process of claim 1 wherein the alkyl phenol is a phenol containing two (2) alkyl groups, said phenol ranging in molecular weight from 178 and upward.
Claim 3
Dependent Claim
38 words
The process of claim 2 wherein the alkoxylated substrate is selected from the group consisting of ethoxylated alkyl phenols wherein the alkyl of the ethoxylated alkyl phenols contain from eight to 20 carbon atoms, and ethoxylated fatty alcohols.
Claim 4
Dependent Claim
19 words
The process of claim 1 wherein the alkyl phenol comprises a mixture phenols containing one and two alkyl substituents.
Claim 5
Dependent Claim
168 words
A process for converting polymeric ethoxylated substrates containing one to 50 ethoxylated groups, said substrates being normally insoluble in mineral oil to such an extent that less than 0.10% by weight of the substrate in a SAE oil at ambient temperatures to the corresponding oil-soluble complex comprising: a. admixing for each part by weight of said substrate selected from the group consisting of ethoxylated alkyl phenols wherein the alkyl groups of the ethoxylated alkyl phenols contain from nine to 16 carbon atoms, and ethoxylated fatty alcohols, said ethoxylated fatty alcohols containing 12 to 18 carbon atoms exclusive of ethoxylate groups, with from two to eight parts by weight of alkyl phenol, containing one alkyl group of from nine to 16 carbon atoms to form a reaction mixture, and b. heating said reaction mixture of substrate and alkyl phenol at a temperature ranging from about ambient temperature up to about 175*F, until a mineral oil-soluble complex is produced, and c. allowing said oil-soluble complex to cool to ambient temperatures.
Claim 6
Dependent Claim
42 words
The process of claim 6 wherein the alkyl phenol is selected from alkyl phenols whose alkyl group contains from four to 12 carbon atoms, the mineral oil is a paraffinic oil and the ethoxylated substrate contains from one to 30 ethoxylate groups.
Claim 7
Dependent Claim
42 words
The process of claim 6 wherein the alkyl phenol is selected from alkyl phenols whose alkyl groups contain from four to 12 carbon atoms, the mineral oil is a naphthenic oil and the ethoxylated substrate contains from one to 30 ethoxylate groups.
