Diglycidyl Ether Manufacturing Plant Project Report 2025

The demand for diglycidyl ether is significantly increasing, driven by robust growth in the construction industry. In 2024, global construction spending exceeded USD 2.5 trillion, marking a 10% increase from the previous year. In 2025, China's construction industry is expected to grow by 4%, with a budget allocation of CNY 28.6 trillion (USD 4 trillion) for infrastructure projects. The U.S. construction sector anticipates a 10% increase due to more than USD 1 trillion allocated as infrastructure investments. India plans to invest around USD 200 billion in construction activities, specifically on housing and transportation. This surge in construction activities, also reflected in the Dodge Momentum Index, is leading to growth of the diglycidyl ether market as it is widely used in construction as a key component in adhesives and sealants.

Other elements to consider while establishing a diglycidyl ether plant include raw material sourcing, workforce planning, and packaging. The production of diglycidyl ether relies on several key raw materials, such as epichlorohydrin and bisphenol A, which are sourced from chemical manufacturing facilities. Epichlorohydrin is typically produced through the chlorination of propylene, while bisphenol A is derived from the condensation of phenol and acetone. These raw materials are essential for making high purity diglycidyl ether.

Moreover, to help stakeholders determine the economics of a diglycidyl ether plant, project funding, capital investments, and operating expenses are analyzed. Projections for income and expenditure, along with a detailed breakdown of fixed and variable costs, direct and indirect expenses, and profit and loss analysis, enable stakeholders to comprehend the financial health and sustainability of a business. These projections serve as a strategic tool for evaluating future profitability, assessing cash flow needs, and identifying potential financial risks.

However, challenges such as supply chain disruptions and regulatory compliance issues may threaten supply stability for diglycidyl ether production. To combat this, manufacturers can diversify their supplier base and invest in local sourcing of raw materials. This strategy can mitigate supply chain risks by reducing dependence on single suppliers and ensuring a more resilient production process amidst fluctuating market conditions.

About Diglycidyl Ether

Diglycidyl ether (DGE), specifically diethylene glycol diglycidyl ether (DEGDGE), is an organic compound with the formula C₆H₁₀O₃. It is a colourless liquid primarily used as a reactive diluent in epoxy resins. The production process involves adding diethylene glycol and a Lewis acid catalyst to a reactor, followed by the controlled addition of epichlorohydrin, resulting in a halohydrin that is then de-hydro-chlorinated with sodium hydroxide to form DGE.

DGE was developed in the mid-20th century alongside advancements in epoxy resin technology. Its applications expanded significantly in the 1990s, particularly in coatings and adhesives, due to its favourable chemical properties. However, concerns regarding its safety and potential health effects have led to increased regulatory scrutiny over the years.

Properties of Diglycidyl Ether

Diglycidyl ether (DGE), specifically di(2,3-epoxypropyl) ether, is a colourless liquid. Its molecular formula is C₆H₁₀O₃, and it has a molecular weight of 130.2 g/mol. The boiling point of DGE is approximately 260°C (500°F), and it has a flash point of 64°C (147°F). The density at 25°C is about 1.12 g/cm³, indicating it is denser than water. DGE exhibits a vapour pressure of 0.09 mmHg at 25°C and a vapour density of 3.78, making it heavier than air. It is highly reactive, particularly with acids and bases, and can polymerise under certain conditions, which is essential for its role in epoxy resin formulations.

Manufacturing Process of Diglycidyl Ether

The production of diglycidyl ether (DGE) begins by adding diethylene glycol (C₄H₁₀O₃) and a Lewis acid catalyst to a reactor, where the reaction is initiated. Next, epichlorohydrin (C₃H₅ClO) is introduced slowly to control the exothermic reaction, which typically occurs at temperatures around 70-100°C. This reaction results in the formation of a halohydrin intermediate. Following this, the mixture undergoes dehydrochlorination by adding sodium hydroxide (NaOH), which facilitates the conversion of the halohydrin to diglycidyl ether. The reaction produces by-products such as sodium chloride (NaCl), water (H₂O), and any excess sodium hydroxide. Throughout the process, quality control measures are implemented to measure the epoxy value, ensuring that the final product meets desired purity and reactivity.

Synthesis of Diglycidyl Ether (DGE)

Diglycidyl ether (DGE) is produced through a series of steps, which are described below:

Step 1: Preparation of Epichlorohydrin

Epichlorohydrin can be prepared from glycerol via the following reaction:

C₃H₈O₃ → C₃H₅ClO + HCl

(Glycerol → Epichlorohydrin + Hydrochloric acid)

Step 2: Reaction of Epichlorohydrin with Diol

The next step involves the reaction of epichlorohydrin with a diol (like ethylene glycol). The reaction can be represented as follows:

C₃H₅ClO + HO-CH₂-CH₂-OH → C₆H₁₀O₃+ HCl

(Epichlorohydrin + Ethylene glycol → Diglycidyl ether + Hydrochloric acid)

Step 3: Neutralisation and Purification

The resulting diglycidyl ether may require neutralisation to remove hydrochloric acid. The product can be purified through distillation to obtain the desired purity.

Applications and Drivers of Diglycidyl Ether

The diglycidyl ether market is driven by its use in the production of epoxy resins, which are used in coatings, adhesives, automotives, and electrical insulations. In the automotive sector, DGE enhances the durability and performance of vehicle components. As per industry reports, the total production of passenger vehicles in India reached approximately 28.4 million units from April 2023 to March 2024, which has contributing to the market growth. In the aerospace industry, DGE is crucial for manufacturing lightweight and durable aircraft components. In 2024, major manufacturers like Airbus and Boeing are expected to deliver around 1,500 aircraft, which is also expected to facilitate DGE market’s revenue. Furthermore, government initiatives, such as the U.S. Environmental Protection Agency's (EPA) Green Chemistry Program are encouraging the development of safer chemical processes and products, including DGE. Technological advancements that improve DGE production efficiency, such as algorithm-based planning systems further supports market growth.
