1619-62-1 - Introduction
Diethylmalonate (also known as DMPD or DEP) is an organic compound with the chemical formula C10H18O4.
It is a colorless to pale yellow liquid with a sweet aroma. The compound has good solubility and can be dissolved in many organic solvents. It is a relatively stable compound, relatively stable at room temperature, and is not easy to react with oxygen in the air.
diethylmalonate has a wide range of applications. First of all, it can be used as a plasticizer, widely used in the production of plastics, resins and polymer products to improve its flexibility and ductility. Secondly, it is also used as a fragrance additive and can be used in perfumes, fragrances and cosmetics. In addition, Diethyl dimethylmalonate can also be used as a solvent for rubber products and coatings.
The preparation method of Diethyl dimethylmalonate is usually obtained by reacting ethyl acetate with dimethyl malonate in the presence of an acid catalyst. It is necessary to pay attention to safety protection during the preparation process, avoid contact with skin and inhalation, and ensure that the operating environment is well ventilated.
Regarding safety information, Diethyl dimethylmalonate is a low-toxicity compound. Exposure to prolonged or high concentrations may have certain effects on human health, such as eye, skin and respiratory tract irritation. Therefore, the use of the process should comply with the safety procedures, wear appropriate protective measures, such as wearing gloves, goggles and breathing mask. In addition, it is also a flammable liquid, avoid contact with open flame or high temperature substances, and keep away from fire and heat sources when stored. In case of accidental leakage, appropriate measures shall be taken immediately to clean up and deal with it.
In General, Diethyl dimethylmalonate is a commonly used chemical with a wide range of applications, but it is necessary to pay attention to safe operation and protection during use and preparation.
