Dimethylolurea Chemical Properties,Uses,Production
Chemical Properties
white powder
Uses
In the textile industry in cotton crease- and shrink-proofing, finishing, drying, sizing; in tanning; pesticides; in photographic developers.
Production Methods
Dimethylolurea is produced industrially by the addition of 2 mol of formaldehyde per mole of urea in a stirred vessel. The solution is neutralized with triethanolamine. Urea is added with cooling, and the temperature must not exceed 40 ℃ in this slightly exothermic reaction. After a few hours, the reaction mixture is cooled to room temperature and dihydroxymethylurea crystals form upon cooling. The product is dried in a spray-drying tower.
Purification Methods
Crystallise it from aqueous 75% EtOH. [Beilstein 3 IV 107.]
