Study on the Effect of 1,2-PDO and DEA on Reaction Efficiency of Alcoholysis Processes for Rigid Polyurethane Foam

Abstract:

The reaction efficiency of rigid PU foam alcoholysis in different conditions is studied in this research. The 1,2-propanediol and DEA are respectively used as alcoholysis agent and catalyst in the experiment. The influence of 1,2- propanediol/rigid and DEA/rigid PU foam weight ratios on the decomposed product is examined, and the respective alcoholysis efficiencies are also investigated. According to the experiment, two weight ratios (i.e. 2:1 for 1,2-PDO/rigid PU foam, and 0.1:1 for DEA/rigid PU foam) can be identified to make the reaction more efficient with less 1,2-PDO and DEA inputs.
