Description
| - Analýza sulfonovaných barviv založených na diaminobifenylu s využitím hmotnostní spektrometrie (cs)
- The title dyes, a group of new homo-bireactive disazo reactive dyes having molecular masses of 10001400 Da, were developed because of their potential use as low salt, easy wash-off colorants for cotton. Following dye synthesis from diaminobiphenyls with and without substituents in the 2,2'-positions, negative-ion electrospray ionisation mass spectrometry (ESI-MS) was used to characterise the dyes, The MS obtained were characterised by signals arising from [M - xH](x-) ions plus fragment ions produced by cleavage at C-N bonds adjacent to the azo linkage. In addition, better results were produced when J-acid was the coupler employed rather than H-acid. The characteristic fragmentation behaviour of the studied dyes is discussed and illustrated on selected example.
