Diallyl disulphide, (C3H5)S.S(C3H6), is a light yellow oil of garlic odour, found to the extent of about 60 per cent, in oil of garlic. It is a liquid of specific gravity 1-023, and boils at 80° to 81° at 16 mm. pressure. 

Unsaturated compounds are those organic compounds in which less than four other atoms are attached to one or more of the carbon atoms. Ethylene, C2H4, is an unsaturated compound. Because ethylene involves only carbon and hydrogen, it is an unsaturated hydrocarbon. Propylene, the next more complicated unsaturated hydrocarbon, has the molecular formula C3H6. 

Daltons below the molecular ion. Typically, this ion corresponds to M - (R + 42), where 42 is C3H6. If there is no side chain, as in the cases of estrone, estradiol, and estriol, the substitution on the D-ring can be determined using the following losses from the molecular ions ...

The first term in R (0) accounts for inhibition effects due to chemisorption of CO and C3H6. The second term is required to fit the experimental data at higher concentrations of CO and C3H6. The third term accounts for the inhibition effects of NO. Each rate parameter is of the form... 

According to Demin et al. (125, 126) the steady-state polymerization of ethylene occurs at 5-70°C in the presence of Cr(7r-C3H6)3 and Zr (tt-CsHs) 4. In Ballard et al. (123) the induction period at ethylene polymerization using Zr (7r-C3H6)4 was observed the introduction of hydrogen... 

In the cases of Cr03/Si02 and Cr(7r-C3H6)3/Si02 systems a considerable part of the chromium contained in the catalyst is involved in the propagation center formation. In these catalysts all the ions of the transition metals are on the surface and the active component seems to be the main type of compounds present on the catalyst surface. 

Ethoxylated diamines [R-N(-C2H4OH)(C3H6)N(-C2H4OH)2. An example is ethyoxylated (3) N-tallow-l,3-diaminepropane, where equiv. wt. = 239 and the material has a liquid consistency at 25 °C. 

With the concentration of OH constant in each experiment, simple integration yields [(CH3)2CHOHU = + ku [C3H6]o= k2e k2c,[OH ]... 

A few studies have been carried out on the parent four- and five-membered cyclic sulfones—for thietane 1,1-dioxide (30) by Scala and Colon65 and for thiolane 1,1-dioxide (sulfolane) (31) by Honda and coworkers66 and, later, by Schuchmann and von Sonntag67. In the former compound, the major photochemical process, in the vacuum UV range, is the initial production of a trimethylene (C3H6) biradical and S02 (equation 9). In both the solid- (77 K) and gas-phase photolyses, formation of a triplet biradical appears to be favored. As well as the expected cyclopropane and propylene, ethylene is also obtained during these photolyses, presumably by a cycloreversion process (equation 10). 

This observation is directly related to the observed dramatic electrochemical promotion of NO reduction by CO and C3H6 in presence of 02 on Rh/YSZ upon electrochemical O2 supply to the Rh catalyst surface (Fig. 2.3 and Chapters 4 and 8).
