| titleOfInvention | Colorimetric-fluorescent probe and detection test paper of cyanide/hydrogen cyanide and its preparation method |
| abstract | The invention discloses a cyanide/hydrogen cyanide colorimetric-fluorescent probe and detection test paper and a preparation method thereof. Selenium oxide selectively oxidizes the 2-methyl variable aldehyde group of 2-methyl-6-(N,N-di-n-butylamino)quinoline; under piperidine catalysis, 6-(di-n-butylamino)quinoline- 2-formaldehyde and malononitrile, carry out Knoevenagel condensation reaction at 25°C for 30 to 60 minutes to obtain probe compound 2-(6-(N,N-di-n-butylamino)quinoline-2-methylene)malononitrile; Probe compound 2-(6-(N,N-di-n-butylamino)quinoline-2-methylene)malononitrile with a mass ratio of 1:1000 and polyethylene oxide are dissolved in dichloromethane, dried The film is formed, and the test paper is obtained after cutting. The test paper can detect hydrogen cyanide gas by colorimetric and fluorescent methods, and has the advantages of high sensitivity and high selectivity. It is expected to conduct rapid on-site screening of suspicious objects in counter-terrorism, and has potential application prospects. |
