540-54-5

A clear colorless liquid. Boiling point 46.6°C. Flash point below 0°F. Less dense than water and slightly soluble in water. Vapors are heavier than air. Irritant and narcotic.

1-CHLOROPROPANE(540-54-5) presents a dangerous fire risk. May be incompatible with strong oxidizing and reducing agents. Incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides.

Highly flammable. Slightly soluble in water.

Highly flammable, dangerous fire risk, explosive limits in air 2.5–11%. Irritant and nar- cotic.

Exposure can cause irritation of eyes, nose and throat. May cause nausea, headache, and vomiting. High concentrations may have a narcotic effect.

CLEAR COLOURLESS LIQUID

Used in organic synthesis, pesticides, pharmaceutical intermediates.

Chloro-n-propane is prepared as follows:

1) Zinc chloride and ammonium chloride are mixed homogeneously according to the molar ratio of 1:1, heated and melted, the temperature is controlled at 340 ℃, and the steam of propanol is passed through

Dry the chloride with MgSO4 and fractionally distil. It can be more extensively purified using extraction with H2SO4 as for n-propyl bromide. Alternatively, Chien and Willard [J Am Chem Soc 75 6160 1953] passed a stream of oxygen containing about 5% ozone through the n-propyl chloride for three times as long as was needed to cause the first coloration of starch iodide paper by the exit gas. After washing with aqueous NaHCO3 to hydrolyse ozonides and remove organic acids, the chloride was dried with MgSO4 and fractionally distilled. [Beilstein 1 IV 189.]
