Questions about 1,3-propanediol

Here is some information on the production of 1,3-propanediol; I hope it will be useful to you. This information was also found online. Abroad: Company name, Production capacity (10,000 tons/year), Production method, Location – Degussa: 5 tons/year, Hydrogenation of acraldehyde; Shell: 7.26 tons/year, Using ethylene oxide, Louisiana; Joint venture between DuPont and Degussa: 0.91 tons/year, Hydrogenation of acraldehyde; DuPont Tate&Lyle: 4.5 tons/year, Biological fermentation, Tennessee; DuPont Tate&Lyle: 1.6 tons/year, Biological fermentation (capacity expanded in the second quarter of 2011), Tennessee. Total: 19.27 tons/year. As of 2010, the global production capacity for 1,3-PDO was 20.27 tons/year. The production methods include: the acraldehyde method, the ethylene oxide method, and the microbial fermentation method. It is mainly in the hands of Shell, Dow Chemical, and DuPont. Analysis of domestic 1,3-PDO production capacity: Company name, Production capacity (tons/year), Production method – Shandong Zouping Mingbo Chemical Co., Ltd.: 6,500 tons/year, Ethylene oxide method; Heilongjiang Chenneng Bioengineering Co., Ltd.: 2,500 tons/year, Biological fermentation method (Tsinghua University technology); Henan Tianguan Enterprise Group: 1,000 tons/year, Biological fermentation method (Tsinghua University technology); Shanghai Demao Chemical Co., Ltd.: Biological fermentation method (DuPont technology); Shanghai Petrochemical: Acrolein method (proprietary technology); Anhui Lixing Chemical Co., Ltd.: 10,000 tons/year, Biological fermentation method (currently in pilot stage, with a plan to reach 10,000 tons/year). In addition, Shanghai Demao Chemical Co., Ltd. claims to be able to produce 1,3-propanediol with a purity of over 99.8% using biological methods; its factory is located in Anhui. The main application areas of this product are pharmaceutical synthesis and the cosmetics industry, but its production capacity is not known.

Are there any updates on the manufacturers and their production capacity? Could you share it? Thank you!

Our company has developed a process for producing high-value 1,3-propanediol using ethylene and formaldehyde as raw materials; the raw materials for this process are readily available, and the production costs are lower compared to traditional methods. We look forward to collaborating with various enterprises. Those interested in this technology please contact me.

The technology for producing 1,3-propanediol through fermentation is quite mature. —————————————————————————————— Signature: Discussions on distillation and fine chemical engineering technologies; Group ID: 594042196.
