Thermal Decomposition of 1-Hexanethiol

Abstract

The uncatalyzed thermal decomposition of I-hexanethiol was studied a t temperature varying from 300 to 700" C and was observed to give 42y0 of olefinic hydrocarbons a t 600° C. Diallcyl sulphides were also obtained a t 550° C with a maximum yield of 13.3% a t 650° C. The effect of sulphide catalyst was investigated and nickel sulphide was found to be the most effective: a t low temperature (150-450' C) dihexylsulphide was produced and a t higher temperature (450-600" C) olefinic hydrocarbons were obtained. Very little catalytic effect was observed with molybdenunl and cadmium sulphides.

Thermal transformations of organic compounds of divalent sulfur

“…4 The decomposition is catalysed by metal sulfides and inhibited by cyclohexene. 7 Since in both cases the ratio of the surface to the volume of a reactor does not affect the reaction rate, 8 a free-radical chain mechanism for the thermolysis of alkanethiols has been suggested. 6,9 The main process is accompanied by parallel reactions (4) and (5).…”

In Situ Observations of Abnormal Pore Size Changes of a Zirconium Based Metal-Organic Framework Using Atomic Resolution S/TEM and EELS

“…Upon heating to 500 °C, the FFT showed an increase in the distance between lattice points. The shrinking of the lattice can be attributed to the formation of additional C-S-C and C-S-S-C bonds between the organic linkers which pulls the zirconium clusters closer together [2].…”
