A simple voltammetric method is described for the determination of traces of selenium in gallium arsenide. Differential-pulse cathodic stripping voltammetry permits a direct determination of selenium without preliminary enrichment or separation processes. Selenium can be determined down to levels of

## Abstract A photometer was utilized to measure the intensity of scattered light in toluene / heptane / asphaltenes mixtures. On the scatteringโintensity versus heptaneโtoโtoluene ratio functions, two linear regions can be observed. The intersection of these regions determines the heptaneโtoโtolue
## Allylic phosphine systems were studied as phosphorus-carbon double bond precursors. I -Phenyl and Ibutyl-1 -phospha-l,3-dienes were generated by pyrolysis at 350-460ยฐC of the corresponding diallyl phosphines in a stirred-flow reactor. The unsubstituted phosphadienes generated in this manner dim
