Tri-n-butyl phosphate (TBP)dissolved in kerosene was chosen as extractant for lithium from a model brine having high magnesium-to-lithium ratio and ferric chloride was added to the system.The influen...
Synthesis of Thermo- and Acid-stable Novel Oligosaccharides by Using Dextransucrase with High Concentration of Sucrose
dextransucrase levansucrase thermo-stable acid-stable oligosaccharides
2008/4/19
A method is presented for synthesizing thermo-, acid-stable glucooligosaccharides (TASOG) from sucrose (2.5-4 M) using a dextransucrase prepared from Leuconostoc mesenteroides B-512FMCM. The degree of...
Freezing Point Depression of Polyol-Aqueous Solutions in the High Concentration Range
freezing point depression polyol xylitol
2010/11/22
Freezing points of polyol-aqueous solutions (xylitol, sorbitol, maltitol, lactitol, and hydrogenated corn syrup) were measured in the high concentration (30-60%) range and compared with those of their...
