HCID 1118Sulfuric AcidCatalyst

Procedure

A solution of 1 g of 3,3-dioxo-3-thia-5,8,11-eicosatriynoic acid in 50 cm3 of methanol is heated under reflux in the presence of a sulfuric acid catalyst for 48 hours. The mixture is then filtered at ambient temperature. The methanol is evaporated off under reduced pressure.

Workup

  1. filtrationThe mixture is then filtered at ambient temperature
  2. customThe methanol is evaporated off under reduced pressure
