Barium sulphate or Barium sulfate is a neutral chemical compound formed of barium and sulphate or sulfate ions. Typically, a chemical compound has sulfate or sulphate to its name when it consists of a sulphate anion which is a polyanion formed of sulfur and oxygen. The sulphate polyanion has the molecular formula as SO 4 2-and …

Dehydration of lactic acid was performed over various metal sulphates. BaSO4 was found to show an efficient activity for dehydration of lactic acid to acrylic acid due to the moderate acidity on its surface. Under the optimal conditions, 99.8% lactic acid conversion and 74.0% acrylic acid selectivity were ac
