How will u convert glycol into formaldehyde?

(Mention reaction)

Producing ethylene glycol from a C1 raw material, formaldehyde: It is a process that hydroformylates formaldehyde to produce glycolaldehyde, which is hydrogenated to ethylene glycol. Hydroformylation is carried out in a liquid-phase reaction catalyzed by rhodium dicarbonyl acetylacetonate and a phosphine ligand. Catalyst solution is extracted from the reactor product, and the glycolaldehyde is hydrogenated over a nickel catalyst.

The economics of an integrated plant to make formaldehyde from methanol and convert the formaldehyde to glycolaldehyde and ethylene glycol have been evaluated. Product value of EG from this route is higher than the product value of EG made by the conventional route from ethylene via ethylene oxide.
