What is 4-Tolyl ether?
Chemical properties
Di-p-tolyl ether is a white or colorless flaky or leafy crystals. Almost insoluble in water, soluble in alcohol, miscible with most perfume oils. Mild, green-rosy, somewhat woody odor of great tenacity.
The Uses of 4-Tolyl ether
Di-p-tolyl ether is used to form conformationally chiral molecules in the solid state, while the chirality of 1,3-dimethyl-2-phenoxybenzene arises from the formation of supramolecular helices.
What are the applications of Application
Suggested for use in soap and detergent perfumes, partly as a fixative, partly as a background note in Rose, Geranium, Lavender, New Mown Hay, Fougère and many other perfume types. It is sufficiently mild. not harsh, that it can be utilized in a great variety of fragrance types.
