✦ Synopsis

The reactions of ethanol and propanol with l-l$S were studied over different types of zeolites at 523 and 623 K. The most active of all investigated zeolites is Na-X at 623 K. The first step of the hydrosulphurization of Cz and C3 alcohols is the dehydration of alcohols toward olefins, which react with chemisorbed HzS, giving thiols and other organic sulphur compounds, The role of sodium cations as active sites is stressed. The dehydration of alcohols increases in the presence of HzS.
