The effect of high pressure combined with a sweating technique was studied in purification of organic crystalline chemicals. The dependence of product purity and yield on pressure, pressing period, and mass of charge were determined. Mixtures studied were guaiacol glycerin ether with guaiacol as ...

of appearance, multiple processes, such as physical, chemical, or biological analyses, have been developed to test contamination levels. Levels of organic and inorganic chemicals, such as chloride,copper,manganese,sulfates, andzinc, microbial pathogens, radioactive materials, and dissolved and suspended...

Adsorption, chromatography-based techniques, nanofiltration, and electrodialysis are well-known and consolidated operations for the isolation and purification of valuable biomolecules extracted from several organic residues. This chapter is dedicated to describing briefly the main features of the above technolog...
Industrially, organic acids are mainly obtained by fermentation processes. Fermentation media are very complex systems and for this reason, the downstream processes are quite significant in order to obtain purified compounds. The recovering of citric acid in industry, for example, is commonly based on...
