Abstract:
The present invention relates to a method for preparing acrylic acid from glycerin. More specifically, the present invention provides a method which can improve the selectivity of acrolein by applying a specific catalyst composition and process conditions to minimize the generation of coke carbon of the catalyst, and can prepare acrylic acid with higher productivity for a longer duration of time because a dehydration reaction can be performed for a longer working period while maintaining catalyst activity at a high level during the reaction.

Claim (Index 8):
The method for preparing acrylic acid according to  claim 7 , wherein the catalyst is at least one selected from the group consisting of Mo 12 W 2 V 4 Cu 2 Sr 0.5 O z , Mo 12 W 2 V 4 Fe 2 Sr 0.5 O z , Mo 12 W 2 V 4 Sb 2 Sr 0.5 O z , Mo 10 W 2 V 3 Cu 1  Sr 0.5 O z , Mo 10 W 2 V 3 Fe l Sr 0.5 O z , and Mo 10 W 2 V 4 Sb 1 Sr 0.4 O z .
