Dyes are determined in gelatin-containing sweets. The gelatin must be eliminated first because it interferes with the normal ion-pair extraction of dyes with tri-n-octylamine to chloroform. Techniques such as precipitation of gelatin with organic solvents, and acid and enzymatic digestion

Cobalt phosphate-based organic-inorganic hybrid nanobelts were successfully synthesized in the presence of trioctylamine (TOA) via a solvothermal system. The inorganic cobalt phosphate layers and organic n-octylamine layers in this structure arranged alternately, both of which were parallel to the axial
