An improved method for preparation of 1-propanol nitrate is proposed and the product yield can be increased to 77%therefrom. By using the mixture of nitric acid and ammonium-rnagnesium nitrate (MNAN ) as nitrate agent, the nitration technology and waste acid disposal will be obviously improved,which is benefit to cycled utilization of nitric acid,creating a favourable procedure for industrial manufacture of 1-propanol nitrate.
