Reaction Conditions:
with tetrabutylammomium bromide;potassium hydroxide in dimethyl sulfoxide at 60 - 120;Catalytic behavior;Inert atmosphere;Autoclave;Large scale;Reagent/catalyst;Solvent;
Steps:
2.1; 3.2 The second step: synthesis of tris(3,6-dioxaheptyl)amine
Under a nitrogen atmosphere, a 2-chloroethyl methyl ether 14.92 Kg (157.8 mol, 4 eq) was charged into a 50 L stainless steel reactor.Triethanolamine borate 6.2Kg (39.46mol, 1eq), tetrabutylammonium bromide 1.2Kg and dimethyl sulfoxide 28Kg, heated to 60At °C, 7.75Kg (138mol, 3.5eq) of potassium hydroxide was added in batches, and the reaction was carried out by heating to 120 ° C for 5-6 hours.By GC, a yellow oily liquid tris(3,6-dioxaheptyl)amine 11.01 Kg was obtained by distillation, HNMR purity: 99.4%, yield: 86.3%.
