Aryl benzobisoxazole and aryl benzobisthiazole compounds in the solid state and in solution have completely different photoreactivity. In the solid state, intermolecular π-stacking interactions between these molecules lead to excimer formation. The

Two forms of lead iodate, with different crystalline structures and solubilities in water, have been reported. Previous workers have found that when the compound is prepared from dilute solution with a slight excess of lead nitrate one form is produc

The solubility of calcium bromate monohydrate in water from (−20 to +100) °C has been determined, along with a differential thermal analysis curve indicating loss of water from (130 to 150) °C and decomposition to calcium bromide from (270 to 300

Guanidino compounds were separated and determined by anion-exchange chromatography and electrochemical detection using a basic aqueous eluent and a nickel working electrode. It was found necessary to use a sample clean-up procedure prior to chromatog

Solubilities of alkaline earth metal bromates and iodates in methanol at room temperature have been determined. Magnesium bromate reacts significantly with methanol, so its solubility was also determined at lower temperatures.

The rate, potential and mechanism of the anodic oxidation of aliphatic aldehydes have been found to be highly dependent on solution conditions and electrode material. Aldehyde oxidations in neutral acetonitrile on glassy carbon occur at very positive
