| titleOfInvention | A kind of pyrido selenium diazine compound and its preparation method and application |
| abstract | The present invention relates to selenium-enriched foliage fertilizers, and in particular to a kind of selenium-enriched active ingredient is pyrido selenium diazine compound and its synthetic method and application.The object of the present invention is to provide active constituent pyrido selenium diazine compounds of a kind of selenium-enriched foliage fertilizer and its preparation method and application, the preparation method of chemical combination pyrido selenium diazine compound of the present invention includes the following steps: that (1) is separately added into the phenyl isocyanate of two-(3- amino -2- pyridine) base diselenides and two equivalents in reaction flask, until being heated slowly to reaction solution solidification, solid re crystallization from toluene, obtain yellow crystalline compound, as two-(3- phenylcarbamido -2- pyridine) base diselenides；(2) using toluene as reaction dissolvent, sequentially add the benzoyl peroxide of two-(3- phenylcarbamido -2- pyridine) base diselenides and 1.5 times of equivalents, it is heated to reflux 3 hours, after TLC lamellae detects fully reacting, vacuum concentration drains solvent, crude product obtains faint yellow solid, as target product pyrido selenium diazine with acetone recrystallization. |
