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...
متن کاملIon-exclusion/cation-exchange chromatography (IEC/CEC) on a weakly acidic cation-exchange resin using on acidic eluent,
Ion-exclusion/cation-exchange chromatography (IEC/CEC) on a weakly acidic cation-exchange resin using on acidic eluent, developed by Tanaka et al. in 1994, has been employed to monitor the quality of environmental water samples such as acid rainwater and river water, to analyze body fluid samples such as saliva, and to evaluate water purification by photocatalytic materials.1–8 One advantage of...
متن کاملModeling of Ion-exclusion and Vacancy Ion-exclusion Chromatography on a Strongly Acidic Cation-exchange Resin in the H+ Form
Ion-exclusion chromatography (IEC) can sometimes be used for separation of the weak acids using pure water as mobile phase. Characteristic leading (i.e. frontally tailing) peaks are obtained and retention depends on the concentration of solutes. It was recently shown that this order could be reversed. In vacant ion exclusion chromatography (vIEC) sample flows as mobile phase and pure water is i...
