Yield:2885-00-9 405 g

Reaction Conditions:

with sodium hydrogensulfide;tetrabutylammomium bromide in water;chlorobenzene at 65 - 70; for 16 h;

Steps:

1 Example 1
The second phase (420 g) is distilled to obtain 1-chlorooctadecane (V) (210 g). 210 g of the 1-chlorooctadecane (V), 200 g of chlorobenzene, 180 g of a 32% by weight sodium bisulfide solution in water and 6 g of tetra-butylammonium bromide are added into a 1000 ml four-necked flask with a stirrer, a thermometer and a condenser. At a temperature in the range of from 65 to 70° C., the mixture is reacted for 16 h. The mixture is separated into an aqueous layer and an organic layer. The organic layer is n-octadecanethiol (III) (405 g).
