Nonyl alcohols with a low degree of branching and their derivatives
View Patent ↗The invention relates to nonyl alcohols with a low degree of branching and derivatives produced using them. In particular the present invention relates to mixture of primary nonyl alcohols in which at least 80% of the alkyl chains are linear and at least 15% of the alkyl chains are branched at the 2-carbon position and its derivatives. The low degree of branching produces derivatives that are more elongated and less bulky that similar derivatives produced with more highly branched alcohols.
1. A mixture of nonyl alcohols comprising at least 80% linear nonyl alcohols and at least 15% of branched nonyl alcohols having branching at the 2-carbon position.
2. A plasticizer comprising a diester of a mixture of nonyl alcohols comprising at least 80% linear nonyl alcohols and at least 15% of branched nonyl alcohols having branching at the 2-carbon position with one or more diacids.
3. A plasticizer as claimed in claim 2 wherein the diacid comprises phthalic acid, adipic acid, sebacic acid and succinic acid.
4. A plasticizer comprising a polyester of a mixture of nonyl alcohols comprising at least 80% linear nonyl alcohols and at least 15% of branched nonyl alcohols having branching at the 2-carbon position with one or more polyacids.
5. A plasticizer as claimed in claim 4 wherein the polyacid comprises trimellitic acid and terephthalic acid.
6. An alcohol derivative comprising a polyalkoxylate, sulfate, sulfated polyalkoxylate, or ether amine of a mixture of nonyl alcohols comprising at least 80% linear nonyl alcohols and at least 15% of branched nonyl alcohols having branching at the 2-carbon position.
7. A hard surface cleaning formulation containing an alcohol derivative as claimed in claim 6 .
8. A laundry detergent formulation containing an alcohol derivative as claimed in claim 6 .
