| titleOfInvention | A method for manufacturing methylated melamine-formaldehyde resins |
| abstract | The present invention relates to a method for producing methylated melamine, which is used in a neutral atmosphere by using 0.0001 to 0.1 moles of one or more metal salt catalysts selected from the group consisting of zinc acetate, sodium acetate, potassium acetate, lead acetate, magnesium acetate and sodium methoxide. The methylolation step of reacting the melamine and formaldehyde by proceeding the reaction, the step of removing the unreacted material and water in the reactants after the reaction proceeds using a thin film distillation apparatus, and the salts and ions remaining in the reactants using magnesium silicate It characterized in that it comprises a step of removing, and by using the methylolation reaction under the middle component atmosphere can not only significantly reduce the amount of acid used in the methoxylation step, as a result of the salt remaining in the reactants after the reaction and Methylation due to drastically reduced ionic content Grameen has high production efficiency of the benefits of a high-purity product. |
