| titleOfInvention | Process for the preparation of an aqueous solution of 1,3-dimethylol-4,5-dihydroxy-2-imidazolidinone |
| abstract | A stable aq. solution of 1,3-dimethylol-4,5-dihydroxy-2-imidazolidinone is made by reacting 1 mol. urea with 0.8-1.3 mol. glyoxal and 1.6-2.5 mols. formaldehyde in aq. medium at pH above 7, pref. 7.5-9.5 between 60 and 70 deg.C. At the end of the reaction, the solution is cooled and the pH reduced to 5.0-5.4 with HCl. The colour of the solution may be improved by bleaching with e.g. NACL. Simplicity of process; good colour and stability of product. Uses are in rendering textiles such as cotton crease-resistant. |
