Diethyl succinate, with the CAS number 123 - 25 - 1, is a colorless to slightly yellowish liquid. It has a molecular formula of C₈H₁₄O₄ and a molecular weight of 174.19 g/mol. This product is supplied directly from the factory at a low price, ensuring cost - effectiveness for users. It has a boiling point in the range of approximately 218 - 219 °C and a melting point of around - 21 °C. The density of diethyl succinate is about 1.04 g/cm³ at 25 °C. It is soluble in common organic solvents such as ethanol, ether, and chloroform, but has limited solubility in water.
Diethyl succinate has a wide range of applications in various industries. In the fragrance and flavor industry, it is used as a flavoring agent due to its pleasant, sweet odor. It can be found in some artificial fruit flavors, adding a fruity note to food products and beverages. In the chemical synthesis field, it serves as an important intermediate. It can participate in esterification, transesterification, and other reactions to produce a variety of valuable chemicals. For example, it can be used in the synthesis of pharmaceuticals, plastics, and resins. In the field of coatings and paints, it can act as a solvent or a film - forming agent, improving the performance of the coating such as its drying time and adhesion.
When using diethyl succinate, it should be handled with care. First, make sure the working environment is well - ventilated to avoid the accumulation of vapors. Wear appropriate personal protective equipment, including gloves and safety goggles. In a laboratory setting, when using it for chemical synthesis, measure the required amount accurately using a pipette or a burette. Slowly add it to the reaction mixture while stirring continuously to ensure uniform reaction. In industrial applications, it should be stored in a cool, dry place away from sources of heat and ignition. When transferring it, use proper transfer equipment to prevent spills.
Fragrance and Flavor Industry: A flavor company wanted to develop a new strawberry - flavored beverage. They used diethyl succinate as one of the key flavoring agents. By adding the appropriate amount of diethyl succinate to the flavor formulation, they were able to achieve a more authentic and intense strawberry flavor. The new beverage was well - received in the market, with increased sales due to its improved taste.
Chemical Synthesis: A pharmaceutical research company was synthesizing a new drug. Diethyl succinate was used as an intermediate in one of the reaction steps. Through a series of well - designed reactions involving diethyl succinate, they successfully synthesized the target compound. The use of diethyl succinate in this synthesis process was crucial as it provided the necessary functional groups and molecular framework for the final drug molecule.
Coatings and Paints: A paint manufacturer was looking to improve the performance of their water - based paint. They added diethyl succinate as a co - solvent. After adding diethyl succinate, the paint showed better leveling properties and a shorter drying time. The paint also had improved adhesion to the substrate, resulting in a more durable and aesthetically pleasing coating.
