ABSTRACT:
Novel methods for preparing polycarboxylic compounds which are useful as metal sequestrants and food acidulants are disclosed. These compounds are aconitic and a mixture of aconitic acid, and the lactones of isocitric acid and alloisocitric acid. The compounds can be neutralized to the corresponding salts which, in turn, are metal sequestering agents. The novel methods include chlorination of propane-1,1,2,3-tetracarboxyalic tetraesters.
