The multistage process includes MVR falling film evaporation, two-stage crystallization in a HPD draft tube crystallizer and a HPD MVR crystallizer to produce anhydrous sodium sulfate
that is dried for sale.
After four or five hours of the refluxing, the mixture was cooled to room temperature and was dried by anhydrous sodium sulfate
Contract awarded for West Sea, Coast Guard headquarters supplies (such as anhydrous sodium sulfate
and 33 kinds) for analysis Purchase
Supply of 250 tons anhydrous sodium sulfate
for the industrial detergents' line.
In turn, the mixture is filtered, the silica washed several times with anhydrous ether, and the extracts combined and dried over anhydrous sodium sulfate
Separate the organic layer; add about 500mg of anhydrous sodium sulfate
shake well, filter and inject.
For the following experiments, anhydrous sodium sulfate
was added directly to the samples in the ASE vials before the evaporation step to dry the samples and to avoid the potential formation of an azeotrope.
The pooled ether was concentrated under vacuum and passed through anhydrous sodium sulfate
to remove any residual water.
