To demonstrate the technique comparative diffusion measurements between ferroussulphate radiation dosimetry gels, with and without xylenol orange chelating agent and carbohydrate additives have been undertaken. Diffusion coefficients of 9.7 +/- 0.4, 13.3 +/- 0.6 and 9.5 +/- 0.8 10(-3) cm2h-1 were determined for ferroussulphate radiation dosimetry gels with and without xylenol orange and with xylenol
The reaction of N-haloamidines with enamines affords 1,4-dihydro-s-triazine derivatives as the main reaction product. The dihydro derivatives are aromatisable through oxidation with chloranil. The mass spectra of the isolated products are discussed in detail.
