(E,Z)-2,6-NONADIEN-1-AL DIETHYL ACETAL - Introduction
A FEMA 3378, also known as DEM, is an organic compound. It has the following properties:
1. Appearance: DEM is a colorless to light yellow liquid.
2. Molecular formula: C16H30O2
3. Melting point:-46 ° C
4. Boiling Point: 160-162 ° C
5. Density: 0.858 g/cm
6. Solubility: insoluble in water, soluble in common organic solvents.
The main uses of the
DEM include:
1. Solvent: Due to its good solubility, DEM is often used as a solvent in organic reactions, especially in cold reactions.
2. Catalyst: DEM can be used as a catalyst for organic synthesis reactions, such as hydrogenation reactions and esterification reactions.
3. Functional Surfactants: DEM can be used to prepare surfactants for wetting and dispersing specific materials.
The preparation method of DEM mainly includes:
1. Ethanol and vinyl tert-butyl ether react at a certain temperature, after a series of reaction steps, the DEM product is finally obtained.
2. DEM can also be obtained by the reaction of ethanol and 2,6-nonadiene under acid catalysis.
Regarding the safety information of DEM, here are some suggestions:
1. DEM is a flammable liquid, avoid exposure to open flames and high temperatures.
2. When using DEM, you should wear appropriate protective equipment, such as gloves and protective glasses, and ensure that you operate under well-ventilated conditions.
3. Avoid skin contact and inhalation of DEM vapor, if accidentally contact, should immediately rinse with water.
4. During storage and handling, care should be taken to avoid contact between DEM and strong oxidants and acidic substances.
5. If any discomfort or accident occurs, seek medical help immediately and provide the doctor with the correct compound information.
It should be noted that the above information is for reference only. Correct operating procedures should be followed when using DEM, and please refer to relevant chemical literature and safety manuals.
