Ligroin is the petroleum fraction consisting mostly of C 7 and C 8 hydrocarbons and boiling in the range 90‒140 °C (194–284 °F). The fraction is also called heavy naphtha. [1] [2] Ligroin is used as a laboratory solvent. Products under the name ligroin can have boiling ranges as low as 60‒80 °C and may be called light naphtha.
Petroleum naphtha. Petroleum naphtha is an intermediate hydrocarbon liquid stream derived from the refining of crude oil [1] [2] [3] with CAS -no 64742-48-9. [4] It is most usually desulfurized and then catalytically reformed, which rearranges or restructures the hydrocarbon molecules in the naphtha as well as breaking some of the molecules ...
May 13, 2024 · Bertha Benz (born May 3, 1849, Pforzheim, Germany—died May 5, 1944, Ladenburg) was a German automotive pioneer who was instrumental in the development of the first engine-powered carriage, or automobile. She is best known for embarking on the world’s first long-distance drive in the Patent-Motorwagen, a car built by her husband, Karl Benz.
Ligroin. Ligroin is a refined saturated hydrocarbon petroleum fraction similar to petroleum ether used mainly as a laboratory solvent. It predominantly consists of C 7 to C 11 in the form of about 55% paraffins, 30% monocycloparaffins, 12% alkylbenzenes, and 2% dicycloparaffins. It is nonpolar. Generally laboratory grade ligroin boils at 60 to ...
8032-32-4. Petroleum ether, also known as benzine, X4 or Ligroin, is a group of various volatile, highly flammable, liquid hydrocarbon mixtures used chiefly as nonpolar solvents . Petroleum ether is obtained from petroleum refineries as the portion of the distillate which is intermediate between the lighter naphtha and the heavier kerosene.

Ligroin is used as a laboratory solvent. Products under the name ligroin can have boiling ranges as low as 60‒80 °C and may be called light naphtha. The name ligroin (or ligroine or ligroïne) appeared as early as 1866.
