Propyl disulfide Usage And Synthesis


Chemical Properties

CLEAR COLURLESS TO PALE YELLOW LIQUID

Chemical Properties

Propyl disulfide has a pungent, sulfur-like odor, with penetrating qualities like the odor of onion and garlic.

Preparation

By boiling propyl bromide and Na2S2 in propyl alcohol; from iodine and n-propyl mercaptan; from propyl iodide and sodium thiosulfate by way of sodium propyl thiosulfate, followed by heating.

Taste threshold values

Taste characteristics at 10 ppm: alliaceous, sulfurous, green, vegetative and asefetida nuances.
