Hydrogen peroxide was used to treat polyether polyols by special process. Amount of volatile aldehydes in polyether polyols before and after the treatment was measured. The results show that the treatment process with hydrogen peroxide can effectively reduce volatile aldehydes (e.g. formaldehyde, acetaldehyde, acrolein) in polyether polyols and thus significantly diminish the odor of polyether polyols, which can satisfy the low odor requirement of polyether polyols from the polyurethane industry.
