Methyl methoxyacetate (MMAc) stands out as a highly versatile molecular building block, playing a key role in addressing two critical global challenges: air pollution and plastic waste accumulation. As a core precursor, MMAc enables the production of ethylene glycol (a vital monomer) through catalytic hydrogenation and hydrolysis. Beyond that, it serves as an advanced oxygenated additive in clean fuel technology, proven to drastically cut down NOₓ emissions and advance eco-friendly fuel solutions.
Most notably, for environmental sustainability, the hydrolysis derivative of MMAc—methyl glycolate (MG)—paves the way for a green synthesis route to polyglycolic acid (PGA). This innovative biopolymer boasts exceptional mechanical strength and gas barrier properties, making it an ideal choice for high-performance applications ranging from deep-well drilling tools to food packaging. Crucially, PGA achieves complete enzymatic biodegradation into CO₂ and H₂O, offering a sustainable solution to the pressing global issue of plastic waste. However, the widespread application of PGA has long been hindered by the lack of mature large-scale industrial production technologies for its monomers, resulting in market shortages and high costs—a breakthrough that changes everything is finally here.
Developed by the Dalian Institute of Chemical Physics (DICP), our cutting-edge technology for methyl glycolate production via dimethoxymethane (DMM) carbonylation followed by hydrolysis is now ready for industrialization. Adopting high-efficiency molecular sieve catalysts, this technology features mild reaction conditions and easy scalability, making it perfectly suited for large-scale industrial production of methyl glycolate.
Rigorously validated through laboratory-scale tests, pilot-scale trials, and comprehensive engineering research, the technology has proven its reliability and feasibility. It represents a groundbreaking new pathway for the green and high-quality development of the coal chemical industry, unlocking new avenues for industrial upgrading.
This pioneering technology has successfully passed the achievement evaluation organized by the China Petroleum and Chemical Industry Federation. Experts on the evaluation committee unanimously recognized it for its high innovation, mild reaction conditions, distinct technical advantages, complete independent intellectual property rights, broad application prospects, and internationally leading level—solidifying its position as a game-changing solution in the field.
