Studies on the Condensation Products of Benzoguanamine with Formaldehyde

I. Properties of Methylolbenzoguanamine

Abstract

The reaction of benzoguanamine with formaldehyde was studied in detail, and the results were summerized as follows.
1) The condensation products of benzoguanamine with formaldehyde (mono^-, di^-, tri^-, and tetra-methvlolbenzoguanamines) were obtained in crystalline state from weak alkaline solution.
2) The functionality of benzoguanamine against formaldehyde is 3.5, and activation energy is 1.3 kcal/mol and heat of reaction is 3.8 kcal/mol.
3) The methylolbenzoguanamine is easily alkylated in alcoholic solution by acidic catalyst. The alkylated products are identified by the paperchromatography using the Tollens' reagent and hydrogen iodide as detecting reagents.
