Synthesis route:
Natural extraction: Obtained from natural essential oils such as lemongrass oil and lemon eucalyptus oil through methods such as distillation and purification with sodium bisulfite addition. Chemical synthesis:
Catalytic hydrogenation of citral: The main method in industry is to produce citral by hydrogenation of citral under the action of a catalyst.
Catalytic dehydrogenation of citronellol: In the presence of lead chromium catalyst, citronellol can be dehydrogenated to form citral.
Other methods: such as preparing from pinene through multi-step reactions, or hydrogenating citral in isopropanol under the action of nickel formate/alumina catalyst.
