TL;DR: A procedure has been devised for the separate determination of benzoic and sorbic acids in orange juice based on the steam distillation of these preservatives from an acidified juice into an alkaline trap and recovery of both preservatives were satisfactory.
Abstract: A procedure has been devised for the separate determination of benzoic and sorbic acids in orange juice. It is based on the steam distillation of these preservatives from an acidified juice into an alkaline trap. The distillate is divided into two portions, each of which is treated with potassium dichromate and sulphuric acid, but under different conditions. Drastic oxidation leads to the destruction of sorbic acid and, after re-distillation, allows the determination of benzoic acid at 225 nm (with no interference from sorbic acid). Milder oxidation selectively converts sorbic acid into malonaldehyde, and the latter is subsequently converted into a coloured compound and determined at 532 nm (with no interference from benzoic acid).Recoveries of both preservatives from orange juice were satisfactory.

TL;DR: The morphological changes of two kinds of dichromate crystals grown in gelatin gel are discussed in this paper, where the morphological diagram corresponds to that of K 2 Cr 2 O 7 in the crystal structure and physico-chemical properties.
Abstract: We have found that the crystals of rubidium dichromate (Rb 2 Cr 2 O 7 ) grown in gelatin gel have a rich variety of morphologies such as platelike, spherulitic and diffusion-limited aggregation (DLA)-like shapes. The morphological diagram has been determined in the range of solute and gelatin concentrations from 1.0 to 4.0%, 0.1 to 7.0%, respectively. The diagram corresponds to that of potassium dichromate (K 2 Cr 2 O 7 ) which is similar to Rb 2 Cr 2 O 7 in the crystal structure and physico-chemical properties. However, featherlike crystals have grown in the region of the diagram where the unique helical K 2 Cr 2 O 7 crystals grow. We discuss the morphological changes of two kinds of dichromate crystals grown in gelatin gel.
