Abstract
The present invention relates to a process for the manufacturing of 3-phenylpropan-1-ol, from nature derived starting material, wherein said nature derived starting material comprises not less than 80 wt. % of cinnamaldehyde. In another aspect, the present invention relates to the process, which further comprises the steps: a) conversion of cinnamaldehyde as starting material to 3-phenylpropan-1-ol by a catalytic hydrogenation; b) optional purification of the 3-phenylpropan-1-ol by alkaline water extraction; c) distillation of 3-phenylpropan-1-ol. In a third aspect the present invention relates to use of 3-phenylpropan-1-ol obtained by the process of the invention in perfumes and/or personal care and/or cleaning products.
Claims5
A process for manufacturing of 3-phenylpropan-1-ol from nature derived starting material, the process comprising:
- obtaining the nature derived starting material from a Cassia species, a Cinnamon species, or a combination thereof;
- concentrating the nature derived starting material via a chromatographical separation process or a fractional distillation process, wherein the concentrated nature derived starting material comprises not less than 80 wt. % of cinnamaldehyde;
- converting the cinnamaldehyde in the nature derived starting material to 3-phenylpropan-1-ol;
- purifying the 3-phenylpropan-1-ol by alkaline water extraction, wherein the purifying is carried out by extracting with alkaline water solution with addition of an organic solvent;
- and
- distilling the 3-phenylpropan-1-ol.
