doi:10.3866/PKU.DXHX202208024

Abstract

Abstract:

Starting from ancient poems, this paper explores the chemical knowledge in the romantic and graceful ancient poems with readers and tells the dyeing principle of synthetic Indigo, the detection and identification of wine aroma and the chemical composition of tea from a chemical point of view. The purpose is to let readers have more understanding of the chemical knowledge in poems, stimulate their interest in chemical learning and appreciate the beauty of chemistry.
