| titleOfInvention | A kind of synthetic method of methyl cyanine dye |
| abstract | The present invention relates to a kind of synthetic method of methine cyanine dye, it comprises the following steps: (1) N-methylquinoline-2-thione, methyl p-toluenesulfonate, heterocyclic quaternary ammonium containing active methyl group Add salt and absolute ethanol into the round-bottomed flask, drop triethylamine, and reflux; (2) evaporate part of the solvent from the refluxed solution in the above step (1) under reduced pressure, cool down, and then pump Filter, dry, and recrystallize to finally obtain a finished product of a cyanine dye. The invention has the advantages of simple operation, high synthesis yield, few steps and short time, can effectively avoid the purification treatment of intermediate products, has high synthesis efficiency and low synthesis cost. |
