What is meant by anhydrous basis? A substance is anhydrousif it contains no water. Many processes in chemistry can be impeded by the presence of water; therefore, it is important that water-free reagents and techniques are used. What is the difference between anhydrous and dried basis?
spun, by dissolving a water-soluble PVA-based polymer in a first organic solvent, spinning the solution in a second organic solvent to obtain solidified filaments and wet-drawing of the filaments from which the first solvent is removed, and which are then dried and subjected to a heat ...
KCl was removed via vacuum filtration, and the resultant filtrate was dried in a rotatory evaporator at 70 °C under reduced pressure. Post-precipitation of potassium acetate required additional vacuum filtration. The resulting pale yellow liquid was dried under dynamic vacuum (Schlenk line) at 110...
