*Dimethyl Succinate (DMS)

Dimethyl Succinate (DMS), namely dimethyl succinate, also known as dimethyl succinate, is an organic compound. Its chemical formula is and its molecular weight is 146.14123. The following is a specific description of its appearance:

• Color: Generally, it is a colorless to light yellow liquid. At room temperature, its color is usually light and close to colorless. However, as time passes or storage conditions change, it may turn slightly yellow.

• State: It is in a liquid state at normal temperature and pressure and has good fluidity, which makes it easy to handle and use in industrial production and laboratory operations. For example, when used as a coating additive, it can be easily mixed with other components.

Other: Dimethyl succinate has a certain pungent smell and can solidify after cooling.

1. Chemical Structure and Properties
   • Dimethyl Succinate (DMS) is the dimethyl ester of succinic acid. Its chemical structure is . It belongs to the ester family of compounds and is a colorless to pale - yellow transparent liquid.
   • It has a molecular weight of 146.14, a density of approximately 1.119 g/cm³ (at 20°C), a boiling point of 196.4°C, a melting point of 18 - 19°C, and a flash point of 85°C (closed - cup). It is miscible with most organic solvents and has relatively low solubility in water.
2. Production Methods
   • Esterification Reaction: It is usually prepared by the esterification reaction of succinic acid and methanol in the presence of a catalyst (such as strong acids like sulfuric acid). During the reaction, the carboxyl group (-COOH) in the succinic acid molecule reacts with the hydroxyl group (-OH) in the methanol molecule, eliminating a water molecule and forming an ester bond (-COO -), thus producing dimethyl succinate.
3. Application Areas
   • Organic Synthesis Intermediate: In the field of organic synthesis, DMS is an important intermediate. For example, it can be used to synthesize a variety of bio - active compounds such as drugs and pesticides. It can be further converted into other organic compounds through transesterification reactions, hydrolysis reactions, etc., providing a basis for constructing complex organic molecular structures.
   • Coatings and Paints: As a high - boiling - point solvent, it helps to adjust the drying speed, fluidity, and glossiness of coatings and paints. Its good solubility enables it to dissolve a variety of resins, such as polyester resins, thus improving the performance of coatings and can also enhance the stability and durability of coatings.
   • Fragrances and Flavors: It has a mild fruity aroma and can be used as a component of fragrances and flavors for formulating fruit - scented flavors such as apple and strawberry flavors, adding a natural and fresh fruity scent to products.
   • Plasticizer: In the plastics industry, it can be used as a plasticizer, which can improve the flexibility, processing performance, and cold - resistance of plastic products, making plastic products softer and easier to process and mold.
