Title:
LOW FREE FORMALDEHYDE AMINO RESIN AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2016/072167
Kind Code:
A1
Abstract:
To provide: a method for producing an amino resin, which is capable of effectively decreasing the content of free formaldehyde, and which prevents the amino resin from increase of the formaldehyde content even during the storage thereof; and a low free formaldehyde amino resin which is obtained by this production method. A method for producing a low free formaldehyde amino resin, which is characterized by comprising (1) a step for obtaining a reaction mixture containing an amino resin by subjecting an amino compound and an aldehyde to a polycondensation reaction in a solvent, and (2) a step for refluxing or desolventizing an organic phase by heating the reaction mixture of the above-described step to 80-150°C; and a low free formaldehyde amino resin which is obtained by this production method.
