ABSTRACT:

The objective is to develop an oxidation/condensation route for synthesis of acrylates/methacrylates from syngas. The investigators are also studying the dehydrogenation-condensation routes, based on its merits proven by studies at NCSU/RTI. The thermodynamics of dehydrogenaton-condensation route show its feasibility, and it is likely that the fluid will be more stable under reducing conditions.  Accomplishments for the past quarter are discussed for the following tasks: proprionate synthesis; condensation catalysis; and slurry reactor studies. Some of the highlights are: Eastman has developed an improved catalyst system for the Mo-catalyzed carbonization of ethylene which accelerates the process by 1.5-3 fold. Bechtel has developed the preliminary cost estimates for a conceptual process design to produce proprionic anhydrite via ethylene carbonylation; RTI has continued to further discern the acid-base properties of the two best catalysts (V-Si-Pt 1:10:2.8 and 10% Ta/NALCO 1034-A) for condensation of proprionic anhydride and formaldehyde to give the maximum yield of methacrylic acid.
