Abstract

PURPOSE: To obtain the title substance, a guanidyl group-forming agent, in high purity safely, by controlling the reaction of urea with a dialkyl sulfate in a specific solvent effectively under heating.
CONSTITUTION: One mole each of urea and a dialkyl sulfate are reacted in 7W30 ml of a solvent, e.g. a monocyclic aromatic hydrocarbon such as benzene or toluene, or a lower saturated cmonohydric alcohol such as methanol or ethanol, or a combination of two or more types at 80W100°C to give an O-alkylisourea.
EFFECT: Rapid increase of temperature can be controlled by absorbing the instantaneous heat generation in the reaction with the latent heat of vaporization of the solvent.
