Abstract: A process for the preparation of C4 oxygenate compounds such as threose, erythrose or erythrulose starting from a composition comprising C1-3 oxygenate compounds such as formaldehyde, glycolaldehyde, glyoxal, pyruvaldehyde or acetol, wherein the process is carried out in the presence of a crystalline microporous material having a ring pore structure selected from an eight-membered ring pore structure or a ten-membered ring pore structure.
