Latest Patents

Shan Gao holds a patent for a method of preparing diamino-dicyclohexyl methane (HMDA). This method involves the hydrogenation of diamino-diphenyl methane (MDA). The process begins with the hydrogenation of 4,4'-MDA to produce 4,4'-HMDA. As the catalyst's activity diminishes, the feed is switched to a mixture of 2,4'-MDA and 4,4'-MDA. Once the conversion stabilizes, the feed returns to 4,4'-MDA. This innovative approach allows for the production of 4,4'-HMDA with a trans-trans isomer content of 16-24 wt%, along with a mixture containing 2,4'-HMDA and 4,4'-HMDA, where the content of 2,4'-HMDA is 4-15 wt%.
