Nitroethane is a harmful chemical compound that is a colorless liquid at room temperature. It has an ignition temperature of 410 ° C and a flash point of 28 ° C.
use
Nitroethane is required in organic chemistry for the synthesis of a wide variety of substances, since the carbon atom bound to the nitro group has an acidic character due to the mesomeric stabilization of the anion. For example, nitroalkanes form salts with bases. One of the most important reactions here is the Henry reaction ; Depending on the conditions, nitroalkenes or nitroalcohols can be formed. This reaction is an important way of forming C – C bonds. Nitroethane is also suitable as a special solvent. In nail design nitroethane is used as a bargaining aid use.
