Description

In man-made leather production, DMF is important as a solvent of polyurethane and then is discharged as aqueous solution. DMF is usually recovered by vacuum distillation from the solution, but in this step DMF is decomposed hydrolytically into formic acid and dimethylamine. To suppress DMF decomposition, the distillation temperature must be lowered. Experiments were carried out on DMF decomposition rate to confirm the validity of vacuum distillation, and the results showed the temperature dependence of DMF decomposition.
