Claims
- 1. A process for the preparation of 2-hydroxymethyl-1, 3-propanediol which comprises the treatment of bis-(hydroxymethyl) acetaldehyde with an aldehyde carbonyl group reducing agent selected from hydrogen adsorbed on a hydrogenation catalyst or an alkali metal dissolving in a lower alkanol.
- 2. A process for the preparation of 2-hydroxymethyl-1,3-propanediol which comprises the treatment of bis-(hydroxymethyl)acetaldehyde with an aldehyde carbonyl group reducing agent selected from hydrogen adsorbed on a platinum, rhodium or palladium hydrogenation catalyst, or an alkali metal dissolving in a lower alkanol.
- 3. A process as defined in claim 2, wherein the aldehyde carbonyl group reducing agent is hydrogen adsorbed on a platinum hydrogenation catalyst.
- 4. A process as defined in claim 2 wherein the aldehyde carbonyl group reducing agent is hydrogen adsorbed on a rhodium hydrogenation catalyst.
- 5. A process as defined in claim 2 wherein the aldehyde carbonyl group reducing agent is hydrogen adsorbed on a palladium hydrogenation catalyst.
- 6. A process as defined in claim 2 wherein said alkali metal dissolving in a lower alkanol is sodium dissolving in ethanol.
