Abstract
Subject matter of the present invention is a method for the production of fatty alcohols from alternative, renewable natural raw materials, the use of the fatty alcohols to produce surfactant intermediates or surfactants and a fatty alcohol composition. More specifically, the invention describes the transesterification of triglycerides and subsequent hydrogenation to fatty alcohols in an industrially desired carbon range, using insect oils, in particular oils from the black soldier fly larvae, as the feed stream or as part of the feed stream.
Claims20
A method for producing fatty alcohols comprising the following steps:
- i) providing a feed stream comprising fatty acid methyl esters, wherein
- a) the fatty acid methyl esters were obtained from an insect oil,
- b) at least 92 wt % of the fatty acid methyl esters obtained from the insect oil have alkyl chain lengths >C10, and
- c) at least 20 wt % of the fatty acid methyl esters obtained from the insect oil have alkyl chain lengths in the range of C12 to C14,
- ii) the fatty acid methyl esters are fractionated to remove the majority of longer carbon chain lengths of C16 and higher to obtain fractionated fatty acid methyl esters, and
- iii) hydrogenating the fractionated fatty acid methyl esters to form fatty alcohols.

14-15. (canceled)
A fatty alcohol composition, wherein the composition comprises more than 95 wt % fatty alcohols and wherein more than 95 wt % of the fatty alcohols are linear, are saturated and have a terminal hydroxy group, wherein
- a) at least 40 wt % of the fatty alcohols have alkyl chain lengths in the range of C12 to C14;
- and
- b) at least 92 wt % of the fatty alcohols have alkyl chain lengths >C10;
- and
- wherein the weight fraction of C14 fatty alcohols is less than a third of the weight fraction of the C12 fatty alcohols.
