Abstract

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.

Claims (2)

1. A mixture of derivatives of nonyl alcohols produced by derivatizing 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 mixture as claimed in claim 1 wherein the derivatives comprise esters of dicarboxylic acids, esters of polycarboxylic acids, alkoxylated alcohols, sulfated alcohols, sulfated alkoxylated alcohols, and alcohol ether amines.
