Definitions
- This invention is directed to a process for making a 1,3- diether compound represented by the formula:
- water is also present in the feed to the reaction.
- concentration of water in the feed can be up to about 35% w/w based on the combined weight of aldehyde and alcohol in the reaction mixture and is preferably from about 1% w/w to about 10% w/w, eg about 5% w/w.
- This reaction produces a mixture of products principally containing the unreacted aldehyde and alcohol, the corresponding alkoxyaldehyde and the unsaturated acetal, the desired acetal and water.
- the desired acetal is separated and the other organic components and some of the water can be recycled to the reactor where the acetal is formed.
- the acetal is converted to the diether by catalytic hydrogenation.
- the hydrogenation reaction is suitably carried out at hydrogen pressures of about 650 kPa to about 35,000 kPa, preferably from about 1,500 kPa to about 20,000 kPa, more preferably from about 3,000 kPa to about 17,500 kPa eg from about 4,500 kPa to about 7,500 kPa.
- the catalyst composition suitably has a catalytic metal content of about 0.05% w/w to about 80% w/w.
- a relatively less active metal such as eg nickel
- a relatively more active metal such as palladium
- the preferred range for the less active catalytic metals is suitably from about 20% w/w to about 80% w/w
- the preferred range is suitably from about 0.05% w/w to about 20% w/w.
