Understanding the fundamental chemical properties and synthesis pathways of an industrial chemical is crucial for formulators, researchers, and procurement specialists. Dimethyl Glutarate (CAS 1119-40-0), a diester derived from glutaric acid, possesses distinct characteristics that make it valuable across various applications. As a prominent Dimethyl Glutarate manufacturer in China, we offer insights into its chemical makeup and production methods.

Dimethyl Glutarate, with the molecular formula C7H12O4 and a molecular weight of 160.17 g/mol, is structurally characterized by a five-carbon chain with methyl ester groups at both ends. This diester structure imbues it with its key properties, including its role as a solvent and an intermediate. Its appearance is a colorless, transparent, oily liquid, and it is known for its faint, agreeable odor. The melting point is around -42.5°C, while its boiling point is approximately 96-103°C at 15 mm Hg. Its density is about 1.09 g/mL at 25°C. These physical properties, particularly its relatively low vapor pressure and high flash point (218°F), contribute to its safe handling and application in industrial settings.

The chemical reactivity of Dimethyl Glutarate is typical of esters. It is susceptible to hydrolysis, reacting with strong mineral acids and strong alkalis to yield methanol and glutaric acid. It is also incompatible with strong oxidizing and reducing agents. However, its stability under normal storage conditions, when kept sealed and shaded in a dry, cool, well-ventilated place, makes it a reliable material for industrial use. The purity of Dimethyl Glutarate, typically exceeding 99%, is a testament to refined manufacturing processes, ensuring minimal side reactions in downstream applications.

The synthesis of Dimethyl Glutarate commonly involves the esterification of glutaric acid with methanol. A prevalent method involves reacting glutaric acid with excess methanol in the presence of an acid catalyst, such as sulfuric acid or a Lewis acid, under reflux conditions. Alternatively, glutaric anhydride can be reacted with methanol. The reaction is typically followed by purification steps, such as distillation under reduced pressure, to achieve the desired high purity.
