With the development of a variety of explosive performance of the increasingly high demand. Ask the explosive energy as high as possible on the other hand requires explosives safety performance as good as possible . Since supramolecular β-CD cavity and the presence of nitro derivatives , which can be prevented with the object with the object after oxidation , photolysis , hydrolysis, moisture absorption , improve the apparent stability of the object , so the paper first β- cyclodextrin and RDX , HMX was studied with the situation , and the β- cyclodextrin nitrated prepare a variety of groups with different number of nitrate nitro derivatives of β- cyclodextrin Finally studied the β- cyclodextrin nitro derivatives with RDX , HMX with the situation . 1 UV absorption spectrum method , obtained β-CD and RDX, HMX with a molar ratio of 1:1 for ; method using a saturated aqueous solution of β-CD and RDX, HMX in a molar ratio of 1:1 means carried out with the obtained solid complexes by IR, XRD and other methods that the β-CD and RDX, HMX formation of complexes between . 2 were mixed with nitric acid and sulfuric acid nitrate as nitrating agent for the nitration β-CD , by thin layer chromatography and column chromatography , to give the number of β- cyclodextrin nitrate , determined by elemental analysis of the β- cyclodextrin nitrate nitrogen content of the product to determine the number of nitrate ester groups , respectively 6,11,14,16,17,18 3. by UV absorption spectroscopy methods derived β- CDN6, β-CDN11, β-CDN14, β-CDN16, β-CDN17, β-CDN18 and RDX, HMX molar mixing ratio of 1:1 ; using saturated solution method for β-CDN6, β-CDN11, β-CDN14 , β-CDN16, β-CDN17, β-CDN18 and RDX, HMX in a molar ratio of 1:1 with the manner of its product with , respectively, using IR, DSC, XRD, characterized by NMR and other methods , the results show that β-CDN6, β-CDN11, β-CDN14, β-CDN16, β-CDN17, β-CDN18 and RDX, HMX formation of complexes between . 4 by measuring the 50% drop height characteristic method of β-CDNn/RDX complexes and complexes were β-CDNn/HMX impact sensitivity performance evaluation results show that with the β-CDNn contain nitrates number (n ) reduction ( ie, degree of reduction as nitrification ), β-CDNn/RDX complexes and complexes β-CDNn/HMX impact sensitivity decreased rapidly.
