The invention relates to a process for producing methacrylic acid, comprising: converting a C3-oxygenate into propanoic acid, wherein said C3-oxygenate is a compound selected from the group consisting of 1-propanol, monopropylene glycol, monohydroxyacetone, 2-hydroxypropanal, glycerol and dihydroxyacetone; and reacting the propanoic acid with formaldehyde or a precursor of formaldehyde into methacrylic acid. Said C3-oxygenate preferably contains 2 oxygen atoms, and most preferably it is monopropylene glycol. |
