1. The Effects of Wash Solvents on Cation-Exchange Capacity Measurements

Author:
C. R. Frink
Source:
Soil Science Society of America journal 1964 v.28 no.4 pp. 506-511
ISSN:
0361-5995
Subject:
acetates; acetone; aluminum; ammonium; calcium; cation exchange capacity; centrifugation; chlorides; clay; dielectric properties; dioxane; hydrolysis; montmorillonite; organic matter; sodium; solubility; solvents; washing
Abstract:
... The CEC of a strong acid-exchange resin, four clays, and several soils was determined using various cations for saturation and a wide variety of solvents for removal of the excess electrolyte. Precipitation of the salts in the solvents was avoided by using the more soluble acetates of the monovalent ions and the chlorides of the polyvalent ions, and by diluting the occluded volume of salt solution ...

Abstract:
... The antioxidant activity of mycelia extracts produced from the submerged cultures of Aspergillus candidus CCRC 31543 was investigated. Inhibition of peroxidation (IP%) of mycelia acetone extracts (MAE) in linoleic acid peroxidation was equal to that of BHA and significantly (p < 0.05) higher than that of alpha-tocopherol. As measured by the Rancimat method in lard, MAE showed marked antioxidant ac ...

Free fatty acids (FFA), fatty acid methyl esters (FAME) and monoacylglycerols (MG) of vegetable oils or animal fats have very close molecular sizes and they cannot be baseline-separated on a single Phenogel column (100 Å, 300 mm x 7.8 mm ID, 5 μm) by using tetrahydrofuran (THF) as the mobile phase. When toluene is ...

Abstract:
... Cassava, due to its high starch content and low cost, is a promising candidate substrate for large-scale fermentation processes aimed at producing the solvents acetone, butanol and ethanol (ABE). However, the solvent yield from the fermentation of cassava reaches only 60% of that achieved by fermenting corn. We have found that the addition of ammonium acetate (CH₃COONH₄) to the cassava medium sign ...

Abstract:
... Rapid dissolution of bagasse and southern yellow pine has been achieved in the ionic liquid (IL) 1-ethyl-3-methylimidazolium acetate ([C₂mim]OAc) by using a dissolution temperature above the glass transition of lignin (ca. 150 °C). When 0.5 g of bagasse or pine is added to 10 g of [C₂mim]OAc, complete dissolution can be obtained in 5–15 min for bagasse at a temperature of 175–195 °C, compared to 1 ...
