Purification process for trimethylolethane

• A process for combined recovery and purifn. of trimethylolethane from aq. reactions mixts. obtained by reacting formaldehyde with propionic aldehyde in the presence of a metal hydroxide comprises a no. of steps including evapg. the reaction mixt. allowing only trimethylolethane to at least partially crystallize as crude trimethylolethane, evapg. remaining water, heating obtained reaction mixt. and/or obtained crude trimethylolethane, and sublimating trimethylolethane for recovery as purified product
