The company said that the new site is the world’s largest single-unit citral production plant.

Citral, often regarded as the 'crown jewel' of fine chemicals, is renowned for its intricate production process and stringent technical requirements, Wanhua said. The product is a crucial intermediate in creating aroma and nutrition and an indispensable component in the fragrance raw materials market.

In 2011, Wanhua started its citral production with small-scale trials. After 13 years of innovation and research, the company said that it has not only achieved optimal product quality from the very first production run but has also laid a solid foundation for expanding its downstream aroma and nutrition businesses.
