NOVELTY - Synthesizing 5-(N-ethyl-N-2-hydroxyethyl amino)-2-pentylamine involves dispersing and dissolving 0.5-100 g nitrate in 100-2000ml organic solvent. The 5-2000g nano oxide or carbonate powder is added and the mixture is stirred at 40-59 Hertz for 10-60 minutes. The organic solvent is evaporated to dryness at 80-120 degrees C and dried under vacuum for 10 hours. The mixture is ground to fine powder size of 0.1-10 microns to obtain catalyst. The catalyst is added in the reaction flask.    USE - Method for synthesizing 5-(N-ethyl-N-2-hydroxyethyl amino)-2-pentylamine (claimed).    ADVANTAGE - The method enables to synthesize 5-(N-ethyl-N-2-hydroxyethyl amino)-2-pentylamine in simple, cost-effective, safe and eco-friendly manner that has high conversion rate, high yield and wide range of industrial applications.    DETAILED DESCRIPTION - Synthesizing 5-(N-ethyl-N-2-hydroxyethyl amino)-2-pentylamine involves dispersing and dissolving 0.5-100 g nitrate in 100-2000ml organic solvent. The 5-2000g nano oxide or carbonate powder is added and the mixture is stirred at 40-59 Hertz for 10-60 minutes. The organic solvent is evaporated to dryness at 80-120 degrees C and dried under vacuum for 10 hours. The mixture is ground to fine powder size of 0.1-10 microns to obtain catalyst. The catalyst is added in the reaction flask. 1.0-1.5L Xylene, 320-330g 5-chloro-2-pentanone, 470-490g N-diethylethanolamine and 1.5-10g catalyst are added and mixture is stirred. The mixture is heated to 90-110 degrees C for 1.5-2.5 hours. The mixture is then warmed under reflux for 2-4 hours and then cooled to room temperature. The mixture is filtered and filtrate is fractionated to obtain 5-(N-ethyl-N-2-hydroxyethyl amino)-2-pentylamine. 90-110 g 5-(N-ethyl-N-2-hydroxyethyl amino)-2-pentylamine is transferred to hydrogenation flask. The methanol, ammonia and raney nickel are added at 40-60 degrees C for 10-14 hours. The system of hydrogen and ammonia is replaced with nitrogen gas. The reaction solution is filtered and the filtrate is fractionated to obtain 5-(N-ethyl-N-2-hydroxyethyl amino)-2-pentylamine. The nitrate is ferric nitrate, cobalt nitrate or nickel nitrate. The organic solvent is methanol, ethanol, propanol, or acetone. The oxides or carbonates include magnesium oxide, calcium oxide, aluminum oxide, silicon dioxide, calcium carbonate or magnesium carbonate.
