生物化学的／生理学的作用

Potassium carbonate(K2CO3) is used as a drying agent for ketones, alcohols, amines, and non-acidic compounds before distillation. It serves as a buffering agent and controls pH during wine and mead production. Potassium carbonate is also used in the extraction of artemisinin, a potent antimalarial drug, from Artemisia annua plant extracts.
