Xinyuan Zhong Chemical: Dual-Driven Synergy, Connecting the World

The story begins in 2010, when Shandong Chengwu Zhongyuan Chemical Co., Ltd. was officially established in the Chengwu County manufacturing Park, Heze City, Shandong Province – the renowned "Hometown of Peonies." As the production parent plant and R&D core of the entire group, the company occupies 75,000 square meters, employs over 300 staff, and has been recognized as a Sci-Tech SME and a High-Tech Enterprise. to over a decade, Shandong Chengwu Zhongyuan Chemical has been dedicated to the R&D and extensive production of fine chemical intermediates, building a strong manufacturing reputation within the sector through solid process technologies and a rigorous condition manage system.

To tap into broader international markets, Shandong Chengwu Zhongyuan Chemical established its holding subsidiary – Hangzhou Xinyuan Zhong Chemical Co., Ltd. – in Hangzhou. Located in Xiaoshan District, Hangzhou, by the banks of the Qiantang River, this subsidiary not only enjoys the locational and informational advantages of the Yangtze River Delta economic zone however also operates as a professional import and export trading company with independent export rights. Serving as the parent company's international window and marketing platform, Hangzhou Xinyuan Zhong Chemical undertakes the crucial mission of promoting the parent company's premium items to overseas markets including Southeast Asia, Europe, and the Americas. This structure truly achieves a virtuous cycle of "manufacturing confidence at the factory, commercial vitality in trade."

Supported by this integrated production-trade framework, the company's core product lines continue to demonstrate strong competitiveness:

Bis(trichloromethyl) Carbonate (Triphosgene / Solid Phosgene): As the company's most representative flagship product, triphosgene (molecular formula: C₃Cl₆O₃) is a white crystalline solid at room temperature, dissolves in various organic solvents such as ether, tetrahydrofuran, and benzene. Its core value lies in serving as a safe substitute to highly toxic gaseous phosgene – whereas traditional phosgene is a gaseous and a highly toxic chemical with difficult handling and storage, triphosgene, as a stable crystalline solid, is far safer to handle, transfer, and store. Notably, in comparable reactions, its dosage is typically reduced to one-third that of phosgene.

In terms of applications, triphosgene is a critical intermediate in the synthesis of pharmaceuticals, pesticides, and polymer materials:

The Shandong production base currently boasts an annual capacity of 8,000 tons, and completed a technological upgrade with an investment of RMB 30 million in 2025, introducing 60 cutting-edge chlorination towers and other equipment. This upgrade ensures stable production capacity while further enhancing security and environmental performance.

Beyond triphosgene, the company has also cultivated a rich portfolio of other fine chemical intermediates:

These items span multiple manufacturing chains, including pharmaceuticals, pesticides, pigment synthesis, and polymer materials, delivering reliable solutions to downstream customers through consistent condition and stable supply capability.

From a modern manufacturing plant in southwestern Shandong to an international trade gateway on the banks of the Qiantang River, Shandong Chengwu Zhongyuan Chemical Co., Ltd. and Hangzhou Xinyuan Zhong Chemical Co., Ltd. are steadily advancing toward a broader global stage under the clear strategy of "parent plant strengthening the foundation, subsidiary expanding the market." Looking ahead, the company will continue to uphold its operating philosophy of "condition as the foundation, integrity as the core," delivering superior items and greater agile services to co-author a new chapter in the chemical sector with partners around the world.
