| Use | can be used for the coloring of plastics, paints, inks and paints. |
| production method | the synthesis of this product is the co-heating of ethylene glycol monoadduct of diimino isoindoline and N-methyl cyanoacetamide in aqueous ammonia solution, it is then treated with silicic acid and condensed with barbituric acid. Reaction equation operating method 14.5g of 1-amino-3-iminoisoindoline and 4.9g of cyanoacetylamine were refluxed in 50ml of methanol for 2H to give 10g of a bright yellow condensate. 4.52g of the above condensate was refluxed with 2.52g of barbituric acid in 80ml of acetic acid to give 6.6g of yellow product. |
