Iodo-aryl carbonates, such as for example, p-iodo-benzyl carbonates, p-iodo-sec-phenethyl carbonates, p-iodo-phenethyl carbonates, p-iodo-phenyl carbonates, 3-(p-iodophenyl)propyl carbonates, 3-(p-iodophenyl)butyl carbonates, 2-(p-iodobenzyl)butyl carbonates and 2-(p-iodobenzyl)-n-hexyl carbonates, for use as radiographic media in connection with such techniques as x-ray applications including myelography, salpingography, lymphography and bronchography. An effective quantity of iodinated organic carbonate provides x-ray contrast, and the compounds of the invention may be characterized generally as carbonates having the general formula ##STR1## wherein R represents an alkyl group having from 4 to 10 carbon atoms and R' represents an iodinated phenyl linked to the ester oxygen through an alkyl chain consisting of 1 to 3 carbon atoms.
碘芳基碳酸酯,例如对碘苯甲酸酯,对碘丙基苯乙酸酯,对碘苯乙基碳酸酯,对碘苯基碳酸酯,3-(对碘苯基)丙基碳酸酯,3-(对碘苯基)丁基碳酸酯,2-(对碘苯甲基)丁基碳酸酯和2-(对碘苯甲基)-正己基碳酸酯,用作与X射线应用相关的放射造影媒体,包括脊髓造影术、输卵管造影术、淋巴造影术和支气管造影术。碘化有机碳酸酯的有效量提供X射线对比度,本发明的化合物通常可表征为具有一般公式##STR1##其中R代表具有4至10个碳原子的烷基基团,R'代表通过含有1至3个碳原子的烷基链连接到酯氧原子的碘化苯基。
