| Use | for organic synthesis, can be prepared polyester resin, polyester plasticizer, polyurethane resin. This product is an effective insect repellent for mosquitoes and flies, and can also be used in the production of cosmetics or as an ink solvent. |
| production method | first, butyraldehyde is synthesized from propylene under the catalysis of alkali or acid, the butyraldehyde condenses itself to produce 2-ethyl-3-hydroxyhexanal. This compound is very unstable and yields 2-ethyl-1, 3-hexanediol by hydrogenation. |
