The present invention relates to a process for producing acrolein by liquid phase dehydration of glycerol by preparing a mixture of a catalyst suspended in an organic solvent comprising one or more vinyl polymers and glycerol; and then mixing and heating the mixture to between 150° C. and 350° C. to dehydrate the glycerol and form acrolein. The vinyl polymers are selected from the group consisting of polyolefins, polystyrene, and mixtures thereof. The polyolefins may be polyethylene, polypropylene, polybutylene, polyisobutylene, polyisoprene, polypentene, or mixtures thereof. The acrolein may be subjected to vapor phase oxidation in the presence of a catalyst, such as a mixed metal oxide, to produce acrylic acid. |
