N- nonane is referred to as a straight-chain alkane having the empirical formula C9H20. The group is called its isomers nonanes. All 35 isomers are colorless flammable liquids.

Properties

Nonanes are colorless, flammable liquids with benzinartigem odor. The unbranched n -nonane melts at -54 ° C and boils at 151 ° C; the nearly spherical 3.3 - Diethylpentan melts at -33 ° C. The flash point of n-nonane is 31 ° C, the ignition temperature at 205 ° C. In water nonanes are insoluble in most organic solvents miscible in all proportions.

Use

Nonanes are components of fuels. In the distillation equipment to be used as entrainer. N- nonane is also used for the synthesis of washing-active substances. In addition, it is used for calibration of measuring equipment of the fire department, with which explosive atmospheres are detected - so-called EX meter.

Hazards

Nonanes are flammable; Nonanbehälter must be kept in a well-ventilated place. They must also be kept away from ignition sources and measures against static discharges must be taken. n -nonane forms explosive mixtures with an air volume fraction from 0.7 to 5.6 %.
