    Prospects of acrylic acid obtaining by acetic acid aldol condensation with formaldehyde are considered. Complex oxide catalysts of the process have been developed. It is shown that raw materials costs in case of acrylic acid production by the condensation method are commeasurable with those in case of its production by oxidation method (main industrial method of acrylic acid production).This method of acrylic acid obtaining may be used as an alternative and enables diversifying the raw materials base of acrylic monomers production. It is shown that the developed catalyst is also efficient in propionic acid aldol condensation with formaldehyde to methacrylic acid.
