Abstract
AbstractThe solubility of N‐guanylurea dinitramide (GUDN, Fox‐12) in binary solvent mixtures was measured. Binary solvents such as dimethyl sulfoxide (DMSO)/water and N,N‐dimethylacetamide (DMA)/water were investigated. The temperature was in the range of 0 °C to 70 °C for DMA‐water and 20 °C to 70 °C for DMSO‐water. The temperature dependence on the solubility was higher in DMA‐water than in DMSO‐water at the same fraction of water. On the other hand, the modeling data was obtained by using the Apelblat equation. The average relative errors are less than 3 %. Supersaturation for crystallization of GUDN in solution can be easily generated by adding water in DMSO (or DMA).
