There are various methods for synthesizing vanillin; the guaiacol-glycolic acid method causes less pollution and yields higher results, making it the widely used synthesis method at present； The lignin method involves obtaining vanillin through reactions such as hydrolysis and oxidation of lignosulfonates in pulp waste liquids; although the raw material cost is low, the yield of the product is low and pollution is severe ； The eugenol method uses eugenol present in cloves oil as the raw material; the resulting product has a good aroma, but the raw material is difficult to obtain and the production cost is high ； The p-cresol method uses p-cresol as a starting material to produce vanillin through multiple reactions such as bromination, etherification, and oxidation; it causes significant corrosion to the equipment.

Hehe, it was so hard for me to find it before,,

May I ask for the name of the factory on the 1st floor and when it will start operating?
