Abstract
The present invention provides a novel process for producing panthenol from pantothenic acid or salts and/or esters thereof. The process makes a “hybrid process” possible to produce panthenol, which is generally more eco-friendly and sustainable and reduces carbon print compared to a pure chemical process.
Claims14
A process for producing a compound of formula (I), comprising the step of reacting a compound of formula (II) with an amino alcohol of formula (III) to obtain the compound of formula (I)
- wherein R is selected from the group consisting of M or hydrogen or substituted or unsubstituted alkyl, wherein M is an alkali metal or earth alkali metal, particularly sodium, potassium, calcium, or magnesium, and each of m and n is independently an integer between 0-5.
A process for producing panthenol, comprising the step i) of fermentative production of pantothenic acid/pantothenate optionally followed by esterification thereof into pantothenic acid esters of formula (II), and the step ii) of reacting the pantothenic acid or salts and/or esters thereof obtained in the step i) with 3-aminopropanol to obtain panthenol.
