Calorimetric Study for the Hydrolysis of Acetonitrile Catalyzed by Acids or Bases
The acid/base-acetonitrile (ACN) mixed system finds extensive application in numerous modern reaction processes. This study investigates the reactions of ACN with mixed aqueous solutions of different concentrations of sulfuric acid, hydrochloric acid, sodium hydroxide, and potassium hydroxide. The results show that heat is generated to varying degrees, and it was found that as the concentration of the strong acid or strong base solutions increases, the amount of heat produced also increases. Particularly under high-concentration conditions, strong acids and bases can induce exothermic hydrolysis of ACN at ambient temperature. Proper use of ACN with mixed solutions of strong acids and strong bases can help prevent safety incidents and also provide insights for future research on the hydrolysis reactions of ACN as a solvent.
期刊介绍:
The journal Organic Process Research & Development serves as a communication tool between industrial chemists and chemists working in universities and research institutes. As such, it reports original work from the broad field of industrial process chemistry but also presents academic results that are relevant, or potentially relevant, to industrial applications. Process chemistry is the science that enables the safe, environmentally benign and ultimately economical manufacturing of organic compounds that are required in larger amounts to help address the needs of society. Consequently, the Journal encompasses every aspect of organic chemistry, including all aspects of catalysis, synthetic methodology development and synthetic strategy exploration, but also includes aspects from analytical and solid-state chemistry and chemical engineering, such as work-up tools,process safety, or flow-chemistry. The goal of development and optimization of chemical reactions and processes is their transfer to a larger scale; original work describing such studies and the actual implementation on scale is highly relevant to the journal. However, studies on new developments from either industry, research institutes or academia that have not yet been demonstrated on scale, but where an industrial utility can be expected and where the study has addressed important prerequisites for a scale-up and has given confidence into the reliability and practicality of the chemistry, also serve the mission of OPR&D as a communication tool between the different contributors to the field.
