N-甲基-14C苄基胺及其亚硝胺的合成
Synthesis of N-methyl-  ̄(14)C benzyl amine and N-methyl- ̄(14)C benzyl nitrosamine
【摘要】 报道了N-甲基-14C苄基胺和N-甲基-14C苄基亚硝胺的合成,比活度约为9.2×1011Bq/mol。由高压液相色谱仪测得的化学纯度和放化纯度均大于95%。
【Abstract】 N-methyl-14C benzyl amine was prepared from benzyl amine through a sequence of trifluoroacylation,ionization, 14C-methylation and hydrolysis. N-methyl-14C benzyl nitrosamine was obtained by treating aqueous 14C-dialkylamine with NaNO2 and H2SO4. The radiochemical purity checked by radio-HPLC and.specific activity of the product was 99% and 9.2 × 1011Bq/mol respectively.
