heptan-1-amine - Reference Information
| LogP | 2.57 |
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| purpose | used as solvent, also used in organic synthesis |
| production method | n-heptanal oxime (see 20965) was dissolved in anhydrous ethanol, heated to boiling, and sodium bar was added, and maintain boiling reflux. After sodium is dissolved, cool the reactant, dilute with water, distill the reaction material, remove ethanol, water and unreacted oxime from the distillate, crystallize out n-heptylamine hydrochloride from the residue, and treat with alkali, heptanamine is available in 60-73% yield. |
