N,N-diethylaniline was synthesized from aniline with bromoethane using tetraethylammonium chloride as phase transfer catalyst under atmospheric presure.
They are formed byatmospheric photochemistry reaction, and could product OH radical, alkyl radical, ozone,carboxylic acid peroxyacetyl nitrates by atmospheric photochemistry reaction.
It includes the function of vacuometer, atmospheric pressure altimeter, thermometer (environment) and pressuremeter (for example the standard pressure meter of sphygmomanometer calibration).
