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 2):
The method for preparing acrylic acid according to  claim 1 , wherein, in Chemical Formula 1, a is 0.5 to 1, b is 0.01 to 0.3, c is 0.01 to 0.3, d is 0.01 to 0.3, and e is 1 to 5.
