Method for producing anis alcohol
View Patent ↗The present invention relates to a method for the preparation of anisalcohol (methoxybenzyl alcohol) by hydrogenation of anisaldehyde (methoxybenzaldehyde) in the presence of Raney nickel and a basic additive, the use of the anisalcohol and hygiene or care products containing anisalcohol.
1. A method for the preparation of anisalcohol by hydrogenation of anisaldehyde, wherein said hydrogenation is carried out in the presence of Raney nickel and a basic additive comprising a metal hydroxide or metal alcoholate.
2. A method according to claim 1 , characterised in that the basic additive comprises sodium hydroxide, potassium hydroxide, sodium methylate or sodium ethylate.
3. The method of claim 1 , wherein the basic additive is an alkali metal hydroxide or alkali metal alcoholate.
4. The method of claim 1 , wherein the basic additive is an aqueous alkali metal hydroxide solution.
5. The method of claim 1 , wherein the basic additive is an alcoholic solution of sodium methylate or sodium ethylate.
6. The method of claim 1 , wherein said basic additive is included in an amount of, based on the pure form thereof, 0.000001–0.1 to 1 based on the weight of the anisaldehyde.
7. The method of claim 6 , wherein said Raney nickel is included in an amount of 0.0001–0.1 to 1 based on the weight of the anisaldehyde.
8. The method of claim 1 , wherein the basic additive is an alkaline earth metal hydroxide.
