The combined extracts were dried with anhydrous sodium sulfate and the filtrate was evaporated to dryness under reduced pressure.
The technique that he developed, electrolysis of potassium fluoride in anhydrous liquid hydrogen fluoride, is still used today, with some modifications.
The sample was maintained at room temperature for 24 h to ensure conversion of any anhydrous cholesterol crystals to the monohydrate form.
The mechanism of buildup of [H.sub.2] O is the massive crystallization of anhydrous minerals.
We are also unable to detect the presence of a separate anhydrous cholesterol or cholesterol monohydrate phase in our binary mixtures, again in contrast to previous reports.
The two most stable species of phosphates are the two extremes of hydrates, the anhydrous salt and the fully hydrated salt.
The plants produced urea ammonium nitrate and anhydrous ammonia.
The vial was sealed, placed in a jar with anhydrous calcium sulfate (Drierite TM) and kept in a cool, dry place until used.
The water in the mantle may be contained either in high pressure hydrous phases, or alternatively as small hydrous defects in nominally anhydrous minerals.
It is interesting to note that SM has more cholesterol monohydrate crystals, whereas HSM has more anhydrous cholesterol crystals.
