Johnson Matthey and Dow License LP Oxo Technology in China – Chemical Engineering

September 30, 2022 | By Mary Bailey

Johnson Mattie plc (JM; London) and Dow (Midland, Michigan) announced that Anqing Shuguang Petrochemical Oxo Co., Ltd. (Anqing) was licensed by LP Oxo Technology to produce approximately 200,000 tons per year of 2-ethylhexanol and 25,000 tons per year of iso-butyraldehyde.

This license, LP Oxo’s second license for Anqing and LP Oxo Technology’s 23rd license served in China, will support the expansion of Anqing’s oxo business in the growing oxo spirit market. The plant is expected to be operational in 2024. Anqing first launched LP Oxo Technology in 2016 to produce 100,000 tons/year of 2-ethylhexanol, 115,000 tons/year of regular butanol and 23,000 tons/year of isobutanol.

Hector Miravete, Global Commercial Director of Catalyst Technologies at Johnson Matthey, says: “This is an important endorsement of our technology. The new design incorporates the improvements we’ve made to ensure LP Oxo Technology remains world-leading. We have started designing the technological process and look forward to working closely with Anqing in the construction of the plant.”

“This second license to LP Oxo Technology from Anqing reinforces the value of this proven technology and its extensive intellectual property portfolio,” said Lauren James, global business director of Dow Industrial Solutions. “Furthermore, this project provides an opportunity for rapid expansion in the Chinese oxalcohol market with new innovations that complement the technology with which Anqing has extensive experience. As the official licensee, Anqing will have access to new innovations in addition to the first plant and access to the expertise of JM and Dow to support this new second plant.”

2-ethylhexanol is used for plasticizing PVC, making special glues and paints. Isobuyraldehyde is used for special coatings and solvents.

LP Oxo technology is a low pressure hydroformation process most commonly used with propylene and syngas (a mixture of hydrogen and carbon monoxide) to produce normal and isobutyraldehyde. These butyric aldehydes are then converted into 2-ethylhexanol (2-EG), normal and isobutanol, which are used mainly for plasticizers, paint production, and specialty coatings and solvents, respectively. Additional LP Oxo technology applications include the isononyl alcohol and 2-propylheptanol process, both growing the alcohol plasticizer alternative 2-EH from mixed butene streams and the C12 to C15 C11 to C14 Fischer surfactant alcohol process. Tropsha olefins. The technology is also used as a component of a process plant to convert heptene-1, which has been extracted from Fischer-Tropsch products, into octane-1 grade itself.
