Abstract
The effects of acid salts (NaHCO3, NaHSO4, NaHSO3 and Na2HPO4) on the reaction of lauryl chloride (RCl) with sodium hydrogensulfide (NaSH) in n-butanol were investigated.
Acid salts react with NaSH to generate hydrogensulfide (H2S), which may react with sodium sulfide (Na2S) to yield NaSH. As a whole, the effect of acid salts depends on the following reaction :
Na2S+NaHSO3→Na2SO3+NaSH
The yield of lauryl mercaptan and the amount of distillation residue were nearly the same as the case of addition of H2S presented in the previous paper. The amounts of water and NaSH did not give so much influence on the yield of mercaptan, but the reaction rate decreased with increasing amount of water.
A considerable amount of disulfide (RSSR) formed even in the n-butanol. In the absence of H2S or acid salts, it was presumed that the following reaction occurred :
