Introduction
Heptanal. The following is an introduction to the properties, uses, preparation methods and safety information of heptanaldehyde:
Quality:
1. Appearance: Heptanal is a colorless liquid with a special pungent odor.
2. Density: Heptanal has a higher density, about 0.82 g/cm³.
4. Solubility: Heptanal is soluble in alcohol and ether solvents, but almost insoluble in water.
Use:
1. Heptanaldehyde is an important intermediate compound, which can be used in the production of biodiesel, ketones, acids and other compounds.
2. Heptanaldehyde is often used in the manufacture of synthetic fragrances, resins, plastics, etc.
3. Heptanaldehyde can also be used as a chemical reagent and can be used in organic synthesis, surfactant and other fields.
Method:
There are two main methods for the preparation of heptanaldehyde:
1. Heptane oxidation: Heptanaldehyde can be prepared by oxidation reaction between heptane and oxygen at high temperatures.
2. Etherification of vinyl alcohol: Heptanal can also be obtained by etherification of 1,6-hexadiene with vinyl alcohol.
Safety Information:
1. Heptanaldehyde has a pungent odor and has an irritating effect on the eyes and respiratory system, so it should be kept away from the eyes, mouth and nose.
2. Heptanaldehyde is irritating to the skin, so it should be rinsed with water immediately after contact.
3. Heptanaldehyde vapor can cause headache, dizziness and other uncomfortable symptoms, and should be used in a well-ventilated environment.
4. Heptanaldehyde is a flammable liquid, so avoid contact with open flames and high temperatures.
