反応手順
The dyestuff used can be prepared as follows: 15 g of 1,4,5,8-tetrachloro-anthraquinone, 75 g of dimethylformamide, 35 g of 2-mercaptobenzthiazole and 30 g of potassium carbonate are heated to 125°-130° C for about 3 hours. After cooling, the dyestuff which has precipitated in attractive red prisms is filtered off and washed with methanol and water. After drying, 34 g of 1,4,5,8-tetra-(2-benzthiazolyl-thio)-anthraquinone = 90% of theory are obtained.
