Patent ID: 8822701

Claim:
A method, wherein the method comprises: a) producing a compound of formula (I): where X is oxygen or sulfur, using a process comprising the successive steps of: 1) reacting, in a reaction medium, diethylenetriamine (DETA) with a urea compound chosen from urea and thiourea, in a DETA/urea compound molar ratio of between 1.2 and 3, at a temperature of at most 300° C.; 2) cooling the reaction medium; 3) removing the residual DETA by distillation in a column under reduced pressure at a temperature, at the bottom of the column, of at most 150° C.; and b) producing a supramolecular material, a pharmaceutical compound, a phytosanitary product, or an additive for paints, paper or lubricants using the compound of formula (I) obtained in step a) as a synthesis synthon or reactant.
