Industrial N-pentane blowing agent 99% Purity,CAS:109-66-0
Introduction
N-pentane is an organic compound that appears as a colorless flammable liquid and is slightly soluble in ethanol, ether, and hydrocarbons. It is mainly used as a solvent, gas chromatography reference liquid, anesthetic, and can also be used to manufacture artificial ice, anesthetic, and synthesize pentanol, isopentane, etc.
Use of n-pentane
N-pentane is used as a low boiling solvent, a foaming agent in the plastic industry, and together with 2-methylbutane, it is used as fuel for automobiles and aircraft, manufacturing artificial ice, anesthetics, and synthesizing pentanol, isopentane, etc; Gas chromatography analysis standard, used for the manufacture of anesthetics, solvents, low-temperature thermometers, as well as for the manufacture of artificial ice, pentanol, isopentane, etc; Used for preparing standard gas, calibration gas, and as a molecular sieve desorption agent; Used as a solvent, gas chromatography reference liquid, and anesthetic, as well as in organic synthesis and the manufacture of low-temperature thermometers.
