  • Process for preparing a branched ester and use thereof
    Patent number: 9587188
    Abstract: The present invention provides a process for preparing a branched ester, comprising reacting a branched primary alcohol composition, having from 8 to 28 carbon atoms and an average number of branches per molecule of from 0.7 to 3.0, said branching comprising methyl and ethyl branches, with an acid. In another aspect, the invention provides a process for preparing a branched ester, pour point depressants for use in fuels, and the use of a branched primary alcohol composition.

  • Nonyl alcohols with a low degree of branching and their derivatives
    Patent number: 9315436
    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.
