Iodine compounds

A few Se-I eompounds, for example Segl, have been identified by Gopal and Milne [92GOP/M1L] in solutions of CS2 or CCI4. In air, no stable eompounds seem to be formed. No thermodynamic data are available for these compounds. [Pg.178]

One of the earliest pertinent kinetic studies of the thermal decomposition of an organic iodide was by Polissar , who in 1930 reported on the decomposition of [Pg.182]

2-diiodoethane to ethylene and iodine in carbon tetrachloride solution. Polissar found the decomposition to be autocatalysed by iodine, with the rate of formation of iodine expressible as d[l2]/dt = [ 211412][12]. Over the range 40-152 °C Arrhenius parameters are 4 = 3.1x10 l.mole. sec and = 29.5 kcal. mole The mechanism proposed was [Pg.183]

According to Arnold and Kistiakowsky the gas phase decomposition of 1,2-diiodoethane is similar to the decomposition in carbon tetrachloride solution. In pyrex glass vessels at 205-230 °C ethylene and iodine are the only products and the reaction in partly heterogeneous. The decomposition obeys the rate law [Pg.183]

Arrhenius parameters are Ai = 4.0x 10 see , j = 36.6 kcal.mole Az = 1.8 X 10 l. mole . sec , 2 = 30.2 kcal.mole Arnold and Kistiakowsky accounted for the results in terms of two simultaneous reactions a direct unimolec-ular elimination of iodine from the parent molecule and an iodine-catalysed reaction. Ogg , however, postulated the following chain reaction for the decomposition, with the first step being rate-determining [Pg.183]

C2H4l2-Fl - C2H4I+I2 C2H4I + I2 - C2H4I2 + I C2H4I C2H4 + I [Pg.183]


It is convenient to describe here certain polyvalent iodine compounds, formed by such substances as iodobenzene and p-iodotoluene. lodobenzeue in chloroform solution reacts readily with chlorine to form iodobenzene dlchlorlde (phenyl iododichloride) (I) ... [Pg.534]

Iodine compounds are important in organic chemistry and very useful in medicine. Iodides, and thyroxine which contains iodine, are used internally in medicine, and as a solution of KI and iodine in alcohol is used for external wounds. Potassium iodide finds use in photography. The deep blue color with starch solution is characteristic of the free element. [Pg.123]
