The compound 4, 4-dinitro-l, 7-diazidoheptane. Use of the compound as a plasticiser in a binder system for a propellant or an explosive composition, e.g. a binder system based on GAP, BAMO or BAMO/GAP, and a plasticiser comprising the compound.
4,4′-Diphenylmethane dicarbamates are produced with high selectivity and in high yield by the one-stage condensation of a N-phenyl carbamate with a methylenating agent in presence of zinc halide as catalyst.

A gasoline product containing a combustion improver and a manufacturing method therefor. A combustion improver is added to gasoline to reduce an ignition point of the gasoline, so that the gasoline product can be applied to a compression ignition engine. Content of the combustion improver is controlled according to a value of octane in base gasoline, so as to implement homogeneity of a nitrogen oxygen equivalent contained in the gasoline product. The combustion improver is selected from at least one of ammonium nitrate and a derivative thereof, nitric acid ester and a derivative thereof, aniline and a derivative thereof, and nitrobenzene and a derivative thereof.
Provided is a gasoline product containing a combustion improver, and a method for preparing the gasoline product. The combustion improver is added to gasoline to reduce an octane number and thus an ignition point of the gasoline, so that the gasoline product can be used in a compression ignition internal combustion engine. The combustion improver-containing gasoline product is a low-octane number gasoline, and is capable of being ignited through compression by an internal combustion engine having a compression ratio in the range from 12 to 22.
