acetic and succinic acids have been separated. Also the presence of malonic acid is indicated. Of these compounds acetic acid is believed to be formed by a further degradation of malonic acid, and consequently the above results show that the respective groups jointed by the ethylenic linkings in clupano-donic acid are CH3·CH2·CH=, =CH·CH2·CH=, three of =CH·(CH2)2·CH=, and =CH·(CH2)2·COOH, provided the terminal
clupanodonate 钾在碱性溶液中在冷却下被高锰酸钾氧化。在氧化产物中,丙酸、乙酸和琥珀酸已被分离。还指出丙二酸的存在。这些化合物中的乙酸被认为是通过丙二酸的进一步降解形成的,因此上述结果表明,在 clupano-donic 酸中通过烯键连接的各个基团是 CH3·CH2·CH=, =CH·CH2 ·CH=、=CH·(CH2)2·CH=和=CH·(CH2)2·COOH中的三个,假设含有羧基的端基为=CH·(CH2)2·COOH。本实验的结果与之前在丙酮溶液中戊基环戊烷的臭氧分解和高锰酸甲酯氧化的实验得到的结果完全一致。
