retention time of nitrate esters in the thermal reactor. Therefore, the production of
nitrous acid can be decelerated to signi cantly improve the safety of the production

process.
The crude products will be put into a distillation system to collect the fraction in
the boiling range of 88 C. The obtained colorless liquid is pure ethyl nitrate,

whose IR spectrum is shown in Fig. 5.4 .

asymmetric and symmetric stretching vibrations of NO 2 , respectively. The bands at
1,455 and 1,382 cm − 1

can be assigned to C
