Abstract: Citric acid or a citrate ester can be prepared by the process comprising the steps of oxidizing isotetralin to form cyclodeca-1,6-diene-4,9-dione, converting the dione into the bis-cyanohydrin derivative, ozonating the bis-cyanohydrin and recovering citric acid or a citrate ester. It is preferred that the isotetralin be prepared by reduction of naphthalene.
