Hydrogen Sulfide → HCID 54565844, compound

Participants

Reaction Steps

0.2 g of sodium are dissolved in 10 ml of absolute ethyl alcohol. After completed alcoholate-formation, 5 g of 2-octenoic acid ethyl ester are added and the solution is cooled to -70°. At this temperature, 10 ml of hydrogen sulphide are condensed into the solution. Subsequently, the whole mixture is immediately transferred into an autoclave, pre-cooled to about -30°, and left by itself overnight at room temperature in the sealed pressure vessel. On the next morning, the autoclave is heated at 50° for a further 2 hours. After cooling to room temperature, the excess hydrogen sulphide is vented off, the reaction product washed with saturated common salt solution, dried and distilled. There are obtained 1.6 g of 3-mercapto-octanoic acid ethyl ester of boiling point 74°/0.4 mm Hg, nD20 1.4538.
