Alkylation of the chrysin dianion

Alkylation of the disodium salt of chrysin in liquid ammonia with methyl iodide gave a mixture of the 6-and 8-monomethyl derivatives, while with prenyl bromide the 6-mono- and the 6,8-diprenyl derivatives were obtained. Nuclear methylation was also achieved by means of dimethyl sulphate. With benzyl chloride as alkylating agent benzylation did not occur under similar conditions, but the 6-C, 7-O-dibenzyl derivative was obtained when the liquid ammonia was replaced by dioxan.

Tritium activity induced in the accelerator building and its correlation to radioactivity of gamma-nuclides

An infrared furnace (ULVAC RHL-410P) was newly applied to the extraction of tritium from concrete samples. After studying the tritium recovery yield regarding temperature and time, the best extraction conditions were set to 800 °C (setting temperature) for 30 minutes under Ar-gas flow of 200 ml/min. Tritium was collected in two cold traps and transferred to a vial for liquid scintillation counting. It took about one hour for the extraction of tritium. Reproducibility and recovery yield of tritium were about 100% compared to the values obtained by the ordinary heating method using an electric furnace. Gamma-ray emitters and tritium of concrete samples collected from several accelerator facilities have been determined. The specific activity of tritium strongly correlated with that of ¹⁵²Eu and ⁶⁰Co, so it was found that tritium was produced by thermal neutron reaction by the ⁶Li(n,)³H reaction. The results indicate that the tritium specific activity in concrete can be estimated from the ⁶⁰Co specific activity obtained easily by -ray measurement.On leave from IHEP, Beijing.This work was supported by Japan Society for the Promotion of Science.
