1-Chlorheptane is a chemical compound from the group of saturated organic aliphatic halogenated hydrocarbons .
Extraction and presentation
1-Chlorheptane can be obtained by reacting 1-heptanol with thionyl chloride in pyridine .
properties
1-Chlorheptane is a moisture-sensitive, little volatile, colorless liquid that is practically insoluble in water. The compound boils at 159 ° C. under normal pressure. According to Antoine, the vapor pressure function results from log 10 (P) = A− (B / (T + C)) (P in bar, T in K) with A = 3.9631, B = 1410.064 and C = −77.511 in the temperature range from 308 K to 433 K. It forms highly flammable vapor-air mixtures. The compound has a flash point of 41 ° C. The ignition temperature is 220 ° C. The substance therefore falls into temperature class T3.
use
1-chloroheptane is used as a synthetic chemical. It was also used when coupling a GC to the ICP-MHMS-FPC for the determination of halogenated hydrocarbons and organometallic compounds.
