Introduction | diisopropylethylamine (DIPEA) is a colorless transparent liquid, insoluble in water, soluble in organic solvents such as acetone. DIPEA is an important pesticide and pharmaceutical intermediate, which can be used to synthesize anesthetics and herbicides, and can also be used as hindered amines to participate in various catalytic reactions. |
Use | N,N-diisopropylethylamine (DIPEA) is a colorless transparent liquid, insoluble in water, soluble in organic solvents such as acetone. DIPEA is an important pesticide and pharmaceutical intermediate, which can be used to synthesize anesthetics and herbicides, and can also be used as hindered amines to participate in various catalytic reactions. biochemical research important organic synthesis intermediates, mainly used in medicine, pesticide intermediate synthesis, can also be used as solvent, condensation agent, Catalyst, for amino acid peptide synthesis, etc. |
preparation | a synthesis method of DIPEA, followed by the following steps: 101.1g(1.0mol) diisopropylamine, 332.0g(2.0mol) tetraethylammonium chloride, 1.5g ethanol, 60g (mol) sodium hydroxide were charged to a ML three-necked flask, heated to reflux, and the reflux temperature was maintained (80 °c). The reaction was completed after 7 hours, cooled to room temperature, and the reaction mixture was freed from the solvent on a rotary evaporator, then washed with 200mL * 3 deionized water, and the three washed oil phases were combined and collected for direct atmospheric distillation, 124.1g of the 125-127 ° C. Fraction was collected, which was the product DIPEA with a yield of 96.2% and a purity of 99.5% as determined by gas chromatography. |
