Title:

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

Document Type and Number:

Japanese Patent JP2016079137

Kind Code:

A

Abstract:

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.SELECTED DRAWING: Figure 1
