This is just a starting point; more participation from everyone will make things even more lively. The forum becomes better with your involvement, so we invite everyone to take an active part in discussions and exchanges here. It’s hot in July, so be careful to prevent fires. --------------------------------------------On July 12, 2023, the technology for synthesizing acrylic acid from acetic acid and formaldehyde, developed jointly by Southwest Chemical Research and Design Institute Co., Ltd. (Southwest Institute), Solutia (Nanjing) Chemical Co., Ltd. (Solutia), and Yankuang Lunan Chemical Co., Ltd. (Lunan Chemical), successfully passed the evaluation of scientific and technological achievements conducted by Zhongke Hechuang (Beijing) Scientific and Technological Achievement Evaluation Center in Chengdu. The expert group listened to the research and technical reports submitted by the project team, reviewed the relevant materials, and after inquiries and discussions, unanimously agreed that the achievement is highly innovative and its overall technology reaches an internationally advanced level. The Southwest Research Institute, Selenis, and Lunan Chemical jointly developed and constructed the first industrial pilot plant for acrylic acid production with an annual capacity of 1,000 tons; it was put into operation in July 2022, enabling the completion of the entire production process. In April 2023, the pilot-scale testing was fully completed, yielding the data required for industrialization. The device operated continuously for a long period, meeting the 72-hour performance criteria; it achieved its designed production capacity and produced qualified acrylic acid, with a product purity of 99.8%, satisfying the first-class standards specified in GB/T 17529.1-2008. The production of acrylic acid via the formaldehyde acetate method offers advantages over the traditional oxidation of propylene, such as lower investment costs, reduced production expenses, readily available raw materials, and a safer manufacturing process. The successful development of a pilot plant scale of several thousand tons represents a significant step forward toward industrializing this entirely new coal-based route for acrylic acid production. Next, Southwest Research Institute and Selenis will work together with Lunan Chemical to fully leverage their respective strengths, deepen cooperation, and overcome challenges. Leverage the resource advantages of large chemical enterprises to further promote the industrial development of acrylic acid.
In September 2022, the world’s first pilot plant with a capacity of 1,000 tons per year for producing acrylic acid using the acetic acid-formaldehyde method, whose process technology was provided by Southwest Chemical Research and Design Institute Co., Ltd. and Solvay Corporation, was successfully commissioned at Shandong Yankuang Lunan Chemical Co., Ltd. The entire production process was operational from the start, and the plant was able to run continuously and stably for 72 hours. This represents another major breakthrough by the Southwest Research Institute in the coal chemical industry chain, marking a solid step forward toward the industrialization of a completely new coal-based process for producing acrylic acid.

On the afternoon of May 18, 2020, Yankuang Lunan Chemical Co., Ltd., Southwest Chemical Research and Design Institute Co., Ltd., and Solutia (Nanjing) Chemical Co., Ltd. held a contract signing ceremony for the acrylic acid pilot plant project at Lunan Chemical. This marked the onset of the full implementation phase of this pilot project, signaling a new chapter for Lunan Chemical in the downstream acetic acid industry.

I hope it will be **vigorously promoted, rather than remaining just verbal support.
