Description
STH iso-octane for hromatogr. (3 ml)
Isooctane (2,2,4-trimetilpentan, iso-octane) — saturated hydrocarbon of aliphatic series.
Isooctane — transparent colorless liquid with gasoline smell; it is water-insoluble, we will dissolve in usual organic solvents; forms constant boiling mixtures, for example with benzene, methyl and ethyl alcohols. Antiknock properties of isooctane are taken for 100 units of scale of so-called octane values. Chemical formula: With (CH3)3 — CH2—CH(CH3)2
Synonym: 2,2,4-trimetilpentan, iso-octane
International name: ISO-OCTANE
CAS No: 540-84-1
Qualification: Imp.
Appearance: transparent colorless liquid
Packing: barrels, 140 kg
Storage conditions: in the aired dry room at low temperature
