Steps:
2
Example 2 In an autoclave, 10 g of NaCN is added to 130 ml of acetone cyanohydrin. Then 6.54 g of methanethiol is added. The solution is then stirred at 60° C. for 2 hours. The solution turns orange. The excess acetone cyanohydrin is then neutralized by adding soda. The solution is then filtered and evaporated to give an orange-yellow solid (amount recovered=33.7 g corresponding to a yield=88%).
