実験手順: A charge of 146.3 grams (1.00 mole) of n-octylmercaptan, 200 m. of isopropyl alcohol and 200 ml. of water were added to a round bottom flask. At room temperature, 46.4 grams (1.16 mole) of sodium hydroxide in 46.4 ml. of water were added to the flask, and exotherm proceeded at 50 to 60° C. Over a 30-minute period, 75.1 grams (1.05 mole) of acrylic acid were added dropwise, and the temperature was then raised to 85° C. and the mixture was allowed to reflux for 2 hours. After cooling to 55° C., 83 grams of 70% aqueous sulfuric acid (0.59 mole) were added, with stirring for 30 minutes, followed by pouring into a separatory funnel. The aqueous layer was drained off and the organic layer was washed with an equal volume of water containing 2% sodium sulfate. After vacuum stripping at 60° C., the reaction product was analyzed to contain 0.04% octylmercaptan and a yield of 98.6% of 3-octylthiopropionic acid product. At room temperature exotherm proceeded at 50 to 60° C to reflux for 2 hours After cooling to 55° C. by pouring into a separatory funnel the organic layer was washed with an equal volume of water containing 2% sodium sulfate at 60° C.
