Electrophoresis, 31(19), 3352-3361 (2010-10-01)
A rapid and sensitive electrophoretically mediated microanalysis method with field-enhanced sample injection (FESI) for in-capillary derivatization was developed to determine selenomethionine (SeMet) and selenomethionine selenoxide (SeOMet). Phthalic anhydride (PA) was selected as the derivatization reagent due to the fast reaction

A new method for the analysis of alcohol ethoxylates (AEs) using electrospray ionisation liquid chromatography/mass spectrometry (ESI LC/MS) is described. The procedure incorporates a novel derivatisation step with phthalic anhydride for the analysis of EO0-20 ethoxylates in a single analysis.
Yuichi Kajita et al.
Journal of the American Chemical Society, 130(51), 17226-17227 (2008-12-04)
An intermolecular nickel-catalyzed addition reaction has been developed where phthalic anhydrides react with alkynes to afford substituted isocoumarins. A mechanistic rationale is proposed, implying reductive elimination of Ni(0) promoted by ZnCl(2) cocatalyst as the key step of the catalytic cycle.

Journal of agricultural and food chemistry, 55(6), 2399-2406 (2007-02-27)
Homogeneous modification of cellulose, isolated with 10% KOH from delignified sugarcane bagasse, was performed in room-temperature ionic liquid 1-allyl-3-methylinidazolium chloride with phthalic anhydride in the absence of catalyst. The results showed the degree of substitution of phthalated cellulosic derivatives, ranging

Journal of chromatography. A, 1203(1), 47-53 (2008-07-25)
The esterification of fatty alcohol ethoxylates (FAEs) with phthalic anhydride in 1,4-dioxane was studied. At 110 degrees C and in the presence of urea, which increased the reaction rate, esterification was completed in 60 min. The reaction yield did not
