| 内容記述 | The reaction of peat humic acid in NaOH aq. with epychlorohydrin had been studied. The conditions of reaction were as follows : the reaction temp. was 70℃ ; the reaction time was about 50?60 minutes ; the end point of reaction was recognized immediately after the gelatinized ｍass vvas obtained. Whether or not the reaction was completed was detected by aids of infrared spectra and other analyses. Natural humic acid being used, the highest yield was about 74％ on the ratio of 1 mol. sodium hydroxide to 4 mol. epychlorohydrin with 150 g humic acid, and epoxy O％ was about 6.5. In the case of using ZnCl_2, SnCl_2 and SnCl_4 as a catalyst, the reaction time was about 30 minutes, but yields and epoxy O％ were not increased. And reactants of the above case did not react to a sclerotic, and were insoluble in any solvents. The oxidized humic acid being used, the resin （softening point was about 60℃） was obtained by the hardening reaction with ethylenediamine | |||||
