Uses

Used in Military and Ammunition Industry:
BIS-(2,2-DINITROPROPYL)ACETAL is used as a propellant and explosive ingredient for its explosive properties, which are crucial in the production of various explosive materials and formulations. Its reactivity and low sensitivity to friction and impact make it a preferred choice in this industry.
Due to its potential for misuse and the associated safety concerns, the handling and distribution of BIS-(2,2-DINITROPROPYL)ACETAL are subject to stringent regulations and controls in many countries, emphasizing the need for secure and responsible use in approved applications.

METHOD FOR PRODUCING BIS-(2,2-DINITROPROPYL)ACETAL

PROBLEM TO BE SOLVED: To provide a highly safe method for producing bis-(2,2-dinitropropyl)acetal (BDNPA) in a high yield. SOLUTION: There is provided a method for producing BDNPA by reacting component (A) 2,2-dinitropropanol, component (B) an acetaldehyde source and component (C) concentrated sulfuric acid, where a mixed liquid (AB) of the component (A) and the component(B) and the component (C) are mixed and continuously reacted at a reaction temperature of 0 to 25°C so that the mixing ratio (molar ratio) of the component (A), the component (B) and the component (C) is (B)/(A)=0.5 to 1.0 and (C)/(A)=0.1 to 1.5 using a circulating-type reactor (3) having a first passage (6) in which the mixed liquid (AB) flows and a second passage (7) in which the component (C) flows.

METHOD FOR PRODUCING AND PURIFYING BIS-(2,2-DINITROPROPYL)ACETAL

PROBLEM TO BE SOLVED: To provide a method for producing BDNPA having high safety and a high recovery rate. SOLUTION: There is provided a method for producing bis-(2,2-dinitropropyl)acetal by continuously reacting a mixture solution of (A) 2,2-dinitropropanol and (B) an acetaldehyde source in the presence of (C) an acid in a flowing passage of a flow-through type reactor, where the (C) acid is a solid acid disposed in the flowing passage, the reaction temperature in the flowing passage is 0 to 50°C, the mixing ratio (molar ratio) of the component (A) to the component (B) (where the component (B) is expressed in terms of acetaldehyde) is 0.5 to 1.0 and a polar solvent is not used as the reaction solvent.

Process and intermediates for the production of BDNPA and BDNPF and other bis(dinitroalkyl)acetals and formals

Bis(dinitroalkyl)acetals and formals having the formula (1) particularly bis(2,2-dinitropropyl)acetal and bis(2,2-dinitropropyl)formal are produced by oxidative nitration of compounds having the formula (2): preferably via a sodium or other alkali metal, or alkaline earth metal, salt of compounds of Formula (2). Certain of the compounds of formula (1) are novel. All of the intermediates of formula (2) are novel and form another aspect of this invention, as does a process for their production by reacting an aldehyde with a nitroalkanol. The process can readily produce a mixture of the dinitro compounds known as BDNPA and BDNPF (also known as A/F) using the non-explosive intermediates, BNPA and BNPF, both of which are novel.
