A method for the determination of fatty alcohol ethoxylates (FAEs) using diphenic anhydride as derivatization reagent and RP-HPLC separation with UV-vis detection is presented and compared to derivatization with maleic, phthalic, and other cyclic anhydrides. With these anhydrides, the reaction

A method for the separation, characterization and determination of fatty alcohol ethoxylates (FAE) and alkylether sulfates (AES) in industrial and environmental samples is described. Separation of the two surfactant classes was achieved in a 50:50 methanol-water medium by retaining AES

Aliphatic and triterpene alcohols present in vegetable oils have been identified and determined by HPLC using UV-vis and MS detection after previous derivatization with diphenic anhydride. The alcoholic fraction was obtained by saponification, extraction and TLC (according to the European

In the course of our work relating to the design of a bihelical structure (I) from diphenic anhydride by tethering with cystine di-OMe, stable, hard, and rigid crystals, mp 215-218 degrees C were isolated in low yields ( approximately 2%).

New pre-column derivatizing reagents: phthalic anhydride, 3-nitrophthalic anhydride, diphenic anhydride, 1,8-naphthalic anhydride and diphenylmaleic anhydride have been developed for resolving chiral compounds having amine groups. Although all of these agents produce derivatives with high molar absorptivities, the later two also
