A Substitute for “Bromine in Carbon Tetrachloride”  Joshua M. Daley and Robert G. Landolt
Benzotrifluoride (BTF) is a suitable solvent substitute for carbon tetrachloride in experiments requiring application of bromine (Br2) in free radical or addition reactions with organic substrates. A 1 M solution of Br2 in BTF may be used to distinguish hydrocarbons based on the ease of abstraction of hydrogen atoms in thermally or light-induced free radical substitutions. Efficacy of minimization of solvent use, by aliquot addition to neat samples, has been established.

A small-scale, easy-to-run wastewater-treatment plant: The treatment of an industrial water that contains suspended clays and soluble salts   Alvaro, Mercedes; Espla, Mercedes; Llinares, Jesus; Martinez-Manez, Ramon; Soto, Juan
Chemistry students are often interested in the chemical principles involved in industrial processes, the pollutants and waste products are generated, and their removal. This experiment introduces students to several theoretical concepts as they apply to real physical and chemical waste-treatment processes.
