    摘要: Homogeneous storage stable solutions of cyanamide in a polyol are made by dehydrating a mixture of an aqueous cyanamide solution and at least one polyol under mild conditions. The aqueous cyanamide solution contains from 10 to 55 wt % cyanamide. The polyol may have a molecular weight of from 62 to 12,000. Polyether and/or polyester polyols having molecular weights from 400 to 12,000 are preferred. Mixtures of high and low molecular weight polyols which are not completely miscible with each other are also preferred. The dehydration is generally carried out at pressures less than 100 mbar and temperatures less than 130.degree. C. The product solution has a cyanamide content of from 0.1 to 50 wt % and a residual water content which is generally no greater than 1 wt %. These homogeneous and storage stable cyanamide in polyol solutions are particularly useful in the production of polyurethanes.
