  • Patent number: 10961180
    Abstract: The invention provides branched trialkylamine oxides with improved properties. The trialkylamine oxides of the invention produced from branched trialkylamines, in one embodiment, can be made using certain branched C10-12 enals and aldehydes. The invention also provides an trialkylamine oxide having the formula: wherein R5, R6 and R7 are independently at least one of C3H7, C2H5, CH3, or H, or mixtures thereof; and wherein R5 and R6 are not H at the same time. In one embodiment, the trialkylamine oxides of the invention can be useful in making various products, for example, as surfactants.

  • Publication number: 20190218171
    Abstract: The invention provides branched hydrophobes for the production of surfactants with improved properties over linear hydrophobes. The invention also provides branched C10-12 enals and aldehydes. The invention additionally provides branched C10-12 enals and aldehydes that are oxidized to branched fatty acids or hydrogenated to branched fatty alcohols and further derivatized to surfactants, through ethoxylation or esterification and other or subsequent reactions. The enals and aldehydes are useful in making branched trialkylamine intermediates useful in making certain surfactants, including amphoteric, cationic and nonionic surfactants. The surfactants which can be produced from the trialkylamine intermediates include the quaternary ammonium compounds of the invention. The quaternary ammonium compounds of the invention are also useful in making the branched enals and/or aldehydes useful in the invention.
