Recently, Beijing Petrochemical Engineering Co., Ltd. and the Pingdu branch of Qingdao Alkali Industry Development Co., Ltd. officially signed a contract for a carbon-neutral technological upgrade project: a circular economy project that utilizes carbon dioxide to produce dimethyl carbonate in an environmentally friendly manner. The signing ceremony was held in Qingdao City, Shandong Province. The project includes process production units, related auxiliary production units, the general layout, as well as supporting utility facilities. The scale of the project is 50,000 tons per year of dimethyl carbonate, with 41,250 tons per year of propylene glycol produced as a by-product. Dimethyl carbonate is a chemically useful material with low toxicity, excellent environmental compatibility, and a wide range of applications. It serves as an important intermediate in organic synthesis; its molecular structure contains functional groups such as carbonyl, methyl, and methoxy groups, which endow it with various reactive properties. In industrial use, it offers advantages such as safety, convenience, low pollution, and ease of transportation. Due to its low toxicity, dimethyl carbonate is a promising \"green\" chemical product. In recent years, the domestic dimethyl carbonate market has seen steady growth in both supply and demand. With the continuous development of new energy technologies, the new energy sector has been expanding as well, leading to strong demand for lithium batteries and electrolytes; as a result, new dimethyl carbonate production projects have been launched one after another. Beiyou Engineering has evolved from its inception in the field of new energy to rapid development; the overall scale of projects it undertakes related to carbonate-based materials continues to increase, placing it among the leaders in China.
