Non-DMF grade material refers to substances that are not compliant with the Drug Master File (DMF) requirements set by regulatory authorities like the FDA. These materials typically do not meet the stringent standards for quality, safety, and manufacturing processes necessary for pharmaceutical use. Consequently, non-DMF materials are often considered unsuitable for use in drug formulations or medical products.
KCl is soluble in DMF
Yes, dimethylformamide (DMF) is a volatile organic solvent. It has a relatively high boiling point of around 153°C and a low vapor pressure at room temperature, but it is still considered volatile compared to non-volatile solvents.

you can try distillation. benzene has a boiling point of 80 deg C and DMF is more like 150 deg C. i don't think it will form an azeotrope (may be wrong though). if it does form an azeotrope and the concentration of DMF is not too high, you can try washing the distillate in a sep funnel with water. DMF is freely miscible in water, whereas benzene is non-soluble in water.
Yes, you can solve 0,04 g of NaCl in 100 g (105 ml) of DMF. From Wikipedia.

Good one material
It means that the material of the Valve has been up to the ASTM Casting Specification ASTM A351 Grade CF8. Used for corrosive or extremely high temperature Non Corrosive services.
DMF Decomposes slowly at room temperature and more rapidly at reflux, releasing dimethylamine and carbon monoxide. This decomposition is catalysed by acidic and basic impurities, and standing DMF for several hours at room temperature with basic drying agents such as calcium hydride or sodium hydroxide leads to noticeable decomposition. Dry DMF can be prepared by drying overnight over barium oxide or 4A molecular sieves, followed by decantation of the drying agent and vacuum distillation (~20 mmHg is a sufficient vacuum to lower the boiling point over DMF to a reasonable value). Dry DMF can be stored over 4A molecular sieves.
