1-Bromopropane is an organic-chemical compound from the group of bromohydrocarbons .
presentation
1-Bromopropane is obtained from 1-propanol by reaction with hydrobromic acid (HBr) in the presence of concentrated sulfuric acid .
properties
1-Bromopropane is a highly flammable, volatile, colorless liquid with a phenol-like odor, which is sparingly soluble in water. When heated, it decomposes, producing, among other things, hydrogen bromide. The compound has an ozone depletion potential of 0.02 to 0.10.
Safety-related parameters
1-bromopropane forms highly flammable vapor-air mixtures. The compound has a flash point of −10 ° C. The explosion range is between 3.4% by volume (170 g / m 3 ) as the lower explosion limit (LEL) and 9.1% by volume (465 g / m 3 ) as the upper explosion limit (UEL). The ignition temperature is 490 ° C. The substance therefore falls into temperature class T1.
