Determination of Adenyl Compounds in Muscle by Ion Exchange Resin

Synthesis of neopentyl glycol and ethylene glycol esters by fatty acids in the presence of acidic ion exchange resin catalyst

A most effective and less energy demanding method of producing fatty esters, diol esters, by esterifying fatty acids, with neopentyl and ethylenglycol alcohols in the presence of an acidic ion exchange resin catalyst(polyestyrendivinylbenzensulfated) was investigated at elevated temperature. In this process an azeotroping agent, toluene, was used to facilitate continuous removal of water by dis...

Esterification Reaction Kinetics Using Ion Exchange Resin Catalyst by Pseudo-Homogenous and Eley-Ridel Models

This work deals with kinetics and chemical equilibrium studies of esterification reaction of ethanol with acetic acid.  The esterification reaction was catalyzed by an acidic ion exchange resin (Amberlyst-15) using a batch stirred tank reactor. The pseudo-homogenous and Eley-Rideal models were successfully fitted with experimental data. At first, Eley-Rideal model was examined for heterogeneous...

Determination of Cyanogenic Compounds in Edible Plants by Ion Chromatography

Cyanogenic glycosides are HCN-producing phytotoxins; HCN is a powerful and a rapidly acting poison. It is not difficult to find plants containing these compounds in the food supply and/or in medicinal herb collections. The objective of this study was to investigate the distribution of total cyanide in nine genera (Dolichos, Ginkgo, Hordeum, Linum, Phaseolus, Prunus, Phyllostachys, Phytolacca, a...

Rapid Determination of Lead in Urine by Ion Exchange.

For routine screening of employees in the lead industry, a method for determination of urinary lead was developed in which this element is removed from urine by means of a chelating agent, eluted, and determined by a modified dithizone method. The method gives values which are about 5% below those obtained by the wet ashing technic, with a precision of ± 2.1% in the range of 2-15 jig. of lead p...
