Latest Patents

Zelikman holds a patent for a method of preparing dicarboxylic acids. This method involves subjecting cycloolefins to ozonolysis in a medium of lower monocarboxylic acids to form an ozonalyzate. The ozonalyzate is then treated with a solution of hydrogen peroxide and passed through a solid acid catalyst, such as Amberlite IR-120 cation-exchange resin. The resulting product undergoes thermal treatment and decomposition to yield dicarboxylic acids like succinic, suberic, or 1,10-decanedicarboxy acids, achieving a yield of 98 percent of the theoretical value and 99.5 percent purity.
