Opened the theory of absolute boiling point of liquids. Designed pycnometer; a device for determining the density of a liquid. Created a hydrated theory of solutions. Found the general equation of state of an ideal gas. He put forward a hypothesis of the origin of oil from carbides of heavy metals.

WORKS “Organic Chemistry” (1861), “Fundamentals of Chemistry” (1869-1871), more than 500 works.
