| titleOfInvention | The synthesis technique of 2 (base of 5 amino, 1,2,4 thiadiazoles 3) 2 methoxyimino acetic acid |
| abstract | The present invention relates to a kind of 2 (5 amino 1,2,The base of 4 thiadiazoles 3) 2 methoxyimino acetic acid synthesis technique,By using cyanoacetamide as initiation material,Through hydroxyl oximate,Methylate,Cyclization,2 (5 amino 1 are made in the reactions such as nitrile solution,2,The base of 4 thiadiazoles 3) 2 methoxyimino acetic acid,Hydroxyapatite is added especially in step 5 as catalyst,(5 amino 1 of intermediate product 2 can be effectively improved,2,The base of 4 thiadiazoles 3) 2 methoxyimino acetonitriles yield and (5 amino 1 of final product 2,2,The base of 4 thiadiazoles 3) 2 methoxyimino acetic acid total recovery,Compared to the total recovery that prior art is no more than 9%,The total recovery of technical scheme provided by the invention reaches 13% or so,Total recovery greatly improved,Reduce cost,Be advantageous to industrial large-scale application. |
