| titleOfInvention | Method for preparing black reversible thermochromic dye |
| abstract | The invention discloses a method for preparing blackA method of color reversible thermochromic dyes. The black reversible thermochromic dye takes a compound (II) as a raw material, and has a structure shown in a formula (II): wherein R is 1 ：C 1 ‑C 10 An alkane; r 2 ：C 1 ‑C 10 An alkane. The compound of formula (II) reacts with various alkylating reagents to prepare corresponding double-alkylated substances, and then the target compound (I) is obtained through hydrolysis reaction. The compound of formula (II) is used as a core fragment substance and reacts with different alkyl reagents, so that a series of black reversible thermochromic dyes can be quickly prepared, the synthesis efficiency is high, and the industrial production of series products is convenient to realize. |
