Abstract

The invention discloses a novel binary eutectic solvent and application of the binary eutectic solvent in NH3 trapping. The eutectic solvent is composed of a component A and a component B; the component A is a proton type ionic salt, and the component B is a phenolic compound or an imide compound. In the eutectic solvent provided by the invention, the component A is a hydrogen bond acceptor, the component B is a hydrogen bond donor, and the component A and the component B have certain weak acidity and can provide double active sites for reversible chemical absorption of NH3. The eutectic solvent provided by the invention has the characteristics of large NH3 absorption capacity, high selectivity, good cycle performance and low volatility, and an efficient, green and environment-friendly absorbent is provided for separation and recovery of NH3 in industrial tail gas.

Description

technical field [0001] The present invention relates to a novel binary deep eutectic solvent, and the deep eutectic solvent in NH 3 The application in capture belongs to the field of green chemical industry. Background technique [0002] NH 3 It is a toxic and harmful alkaline gas, which is the main driver of the formation of most secondary particulate matter in PM2.5, and it will interact with acid gases (SO 2 , NO x ) reaction to generate secondary aerosols, thus causing serious harm to the ecological environment. On the other hand, NH 3 It can be used to produce ammonia water, nitrogen fertilizer, ammonium salt, compound fertilizer, soda ash, etc., so it is widely used in chemical industry, light industry, pharmaceutical, chemical fertilizer and other fields. Therefore, for NH in industrial exhaust 3 Separation and recycling are of great significance. [0003] NH commonly used in industry 3 The capture method is pickling method, which uses an aqueous solution of i...
