Embodiment Construction

[0023] A kind of characteristic CL-20 purity analysis method, adopts calibration curve method to analyze, and described calibration curve method comprises the steps:

[0024] (1) Weigh two parts of CL-20 standard sample (each part is 0.01g-0.05g, accurate to 0.0001g), put them in two 25mL volumetric flasks respectively, dissolve with a proper amount of acetonitrile and dilute to volume; use acetonitrile to dilute the mother liquor Stepwise dilution, the two standard samples were prepared into 3 to 5 different concentrations of the standard test solution (concentration at 5 × 10 -6 g / mL -1 ~5×10 -5 g / mL -1 Within the scope), carry out the chromatographic determination of the above-mentioned standard test solutions with different concentrations under the specified conditions, draw their chromatograms, record the standard sample concentrations and standard sample chromatographic peak heights of all standard test solutions, and then combine the above data with the formula (1.1 ...

Abstract

The invention relates to techniques of analyzing purities of explosives, in particular to a method of analyzing purity of special CL-20 and solves the problem that a method to accurately analyze purity of special CL-20 is not provided presently. The method that performs analysis by a correcting curve method comprises the steps of (1) weighing two CL-20 standard samples, and preparing 3 to 5 standard test solutions different in concentration, performing chromatographic measurement on the standard test solutions different in concentration under specified conditions, drawing their chromatograms,recording standard sample concentrations and standard sample chromatographic peak heights of all the standard test solutions, and calculating correcting curve parameters A and B according to the abovedata; (2) weighing two CL-29 samples under measurement, adding into volumetric flasks, performing chromatographic measurement under the conditions the same as those of the standard test solutions, recording chromatographic peak heights of the samples, calculating concentrations of CL-20 solutions, and reversing according to original masses of the samples, dilution factors of the sample solutionsto obtain CL-20 contents.

Description

technical field [0001] The invention relates to an explosive purity analysis technology, in particular to a special CL-20 purity analysis method. Background technique [0002] Special CL-20 is a kind of special performance in crystal shape, crystal density, particle size distribution, product purity and other indicators obtained by special process, which can meet the special requirements of special CL-20 for blasting operations. Require. However, there is currently a lack of a method that can effectively and accurately analyze the purity of the special CL-20. Contents of the invention [0003] The present invention provides a method for analyzing the purity of idiosyncratic CL-20 in order to solve the technical problem of lacking a method capable of accurately analyzing the purity of idiosyncratic CL-20. [0004] The present invention is realized by adopting the following technical solutions: a method for analyzing the purity of special CL-20, which adopts a calibration ...
