What is THF (Tetrahydrofuran)? - Structure, Uses
WebThe water will stay with the solid mag sulfate, and you'll be left with just THF. There will a fraction of a percent water left in the THF still since mag sulfate is just a quickie drying agent. Sieves can get you the rest of the way there to absolutely bone dry <10 ppm water, around 10-20% w/v sieves in solvent. I'm a bit confused by "massive". WebWe are experiencing problems drying THF and diethyl ether with an MBraun SPS solvent purification system. The solvents have the expected low water content (10-20 ppp according to... Webcontent of THF dried by this method can be re-duced below 0.1% when a batch still is used but is more commonly about 0.5%, depending on the efficiency of the still. Brine extraction is a relatively foolproof method for separating THF from its water azeotrope and is economical, provided a high degree of dryness is. 4 my work spot reform road
