| titleOfInvention | Synthesis method of 2,2' -hydrazine-bis (3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt |
| abstract | The invention provides a synthesis method of 2,2' -hydrazine-bis (3-ethylbenzothiazoline-6-sulfonic acid) diamine salt (ABTS), belonging to the field of organic synthesis. The 2-hydroxybenzothiazole firstly reacts with 2-bromoethane to generate 3-ethylbenzothiazole-2-ketone, then reacts with hydrazine hydrate to generate 2,2' -azino bis (3-ethylbenzothiazoline), then reacts with concentrated sulfuric acid for sulfonation to generate a compound 2,2' -azino bis (3-ethylbenzothiazoline-6-sulfonic acid), and finally reacts with ammonia gas to generate salt so as to obtain 2,2' -biamino-bis (3-ethylbenzothiazoline-6-sulfonic acid) diamine salt. The method has the advantages of cheap and easily obtained raw materials, simple and convenient operation, mild reaction conditions and high yield. |
