抄録

Study was made of the method of separation and confirmation of antioxidants present in vulcanizates by the application of the detection method for antioxidants by the paper electrophoresis method explained in the previous report.<br>Finely-cut vulcanizate samples were extracted with acetone, acetone distilled off from the extraction solution and then dissolved with acetic acid in case it contained amine antioxidant and in ethanolic sodium hydroxide solution in case it contained phenolic antioxidants. There were coupled with p-diazobenzene sulphonic acid to produce azo-dyes, after which, paper electrophoresis was carried on. After passing electric current for an appropriate time, the coloring on the filter paper and the distance travelled were observed and in case of amine antioxidants, these can be easily separated not only when they are mixed in vulcanizates independently but even when two or three kinds are present together in a mixed state. In case of phenolic antioxidants, there are cases in which it was not possible to separate them when two or three kinds were present together in a mixed state. Interference by accelerators or other compounding agents was not observer in the above-mentioned analytical method with the exception when aldehyde amine accelerators were used.
