Disclosed is a method of preparing acrylic acid from glycerol, including: (a) preparing products including allyl alcohol from reactants including glycerol and carboxylic acid; (b) adding a heterogeneous catalyst and a basic solution to the product including allyl alcohol and then performing oxidation, thus preparing a mixture composed of 3-hydroxypropionic acid and acrylic acid; (c) dehydrating 3-hydroxypropionic acid of the mixture composed of 3-hydroxypropionic acid and acrylic acid, thus producing acrylic acid.

Method for producing acrylic acid from glycerol

Disclosed are a method of preparing allyl alcohol and allyl alcohol prepared thereby. The method of preparing allyl alcohol includes adding glycerol with formic acid in an amount of 0.8&#x2dc;2 equivalents relative to 1 equivalent of glycerol, and increasing a reaction temperature to 220&#x2dc;260&#xb0; C. from room temperature at a heating rate of 2.0&#x2dc;7.0&#xb0; C./min so that glycerol and formic acid are reacted.

Method for producing allyl alcohol and allyl alcohol produced thereby

The present invention relates to a heterogeneous catalyst for preparing acrylic acid from allyl alcohol, and a method of preparing acrylic acid from allyl alcohol using the same. More particularly, the present invention relates to a method of preparing acrylic acid from allyl alcohol at a high yield by performing a liquid phase reaction in the presence of a heterogeneous catalyst including gold supported on a carrier.

Heterogeneous catalyst for preparing acrylic acid from allyl alcohol, and method of preparing acrylic acid from allyl alcohol using the same

This invention relates to a method of preparing an ester compound, including adding carboxylic acid to a mixture of glycerol and acetone in the presence of a sulfuric acid catalyst and applying an ultrasonic wave to induce an esterification reaction, and to an ester compound prepared thereby.

Method of preparing ester compound and ester compound prepared thereby

Disclosed is a method for preparing allyl alcohol, wherein glycerol and formic acid are reacted under specific synthesis conditions, thus remarkably increasing the concentration of allyl alcohol in the liquid reaction products and minimizing the production of allyl formate byproduct and the production of unreacted formic acid.
