The effects of hydrogensulfide on the reaction of lauryl chloride (n-RCl) with sodium hydrogensulfide (NaSH) in n-butanol were mainly investigated. In the presence of hydrogensulfide, the yield of lauryl mercaptan increased remarkably and a side reaction (formation of sulfide : 2RCl+Na₂S→RSR+2NaCl) was greatly decreased. From these results, it became clear that the following reaction mainly occurred :
Na₂S+H₂S→2NaSH
Moreover, the amount of water or n-butanol did not give much influence on the yield of mercaptan.
In other experiments, the reactions of sec-RCl with NaSH were investigated. The reactivity of sec-RCl was lower by one half than that of n-RCl. But the reactivity of sec-RCl contained by several % in n-RCl was very low.
