摘要:
AbstractThe Oxidation of iodine by ceric sulfate in sulfuric acid solution has been found to be of second‐order with respect to iodine and first‐order with respect to Ce(IV), by spectrophotometric measurements. CeSO4+2was assumed to be the active species of ceric sulfate. The over‐all rate constants were found to bek0=2.66x IC4l2/M2Iminfor the reaction rate,‐d[I2]/dt=k0[C3(IV)][I2]2in 1.0MH2SO4and K″ = 1.12×108I2/M2·minfor the reaction rate, ‐d[I2]/dt=k′

摘要:
AbstractRefractive indices of several binary solution systems including cyclohexane‐benzene, benzene‐acetic acid, benzene‐ethyl acetate, carbon tetrachloride‐acetic acid and carbon tetrachloride‐ethyl acetate were measured by means of inter‐ferometer. Polarisability constant and collision radius of benzene, acetic acid and ethyl acetate were determined in the light of the theory advanced in the previous

摘要:
AbstractLabelling of rose bengal with iodine‐131 was studied by using carrier‐free NaI‐131 produced at the National Tsing Hua University. The effects ofpH and hydrogen peroxide on the radioactive exchange reaction were investigated. It was observed that as high as 88% of iodine‐131 was exchanged under the optimum conditions found in the present study. The purity of the I‐131 labelled rose bengal obtained by the exchange method was examined by paper chromatography, and was found to be sat

摘要:
AbstractThe reaction of equimolar amounts of NBS with salicylic acid in carbon tetrachloride was found to give tribromophenol, 4‐bromo‐ and 4,6‐(not 4,5)‐dibromo‐salicylic acids, while the same reaction carried out in dioxane yielded only tribromophenol and 4‐bromosalicylic acid and addition of pyridine into the reaction mixture (in dioxane) decreased the yields of the products. The fact that no 4,6‐dibromosalicylic acid could be produced in a dioxane medium is a strong evidence showing that the bromination in dioxane takes place through dioxane dibromide as the
