Abstract
Disclosed is a polycyclic azide desulfurizer, including the following raw materials in parts by mass: 20-35 parts of an alcohol amine, 20-35 parts of an amide, and an aldehyde, which is 10-15 parts of a small-molecule aldehyde or 20-35 parts of a polyaldehyde. Also disclosed is a method for synthesis of the polycyclic azide desulfurizer, including: mixing an alcohol amine with an amide and stirring, heating, adding a catalyst I dropwise, and performing reaction to obtain a monocyclic triazine, heating the monocyclic triazine, mixing with a polyaldehyde and stirring, adding a catalyst II dropwise, and performing coupling while stirring; alternatively, mixing a small-molecule aldehyde with an amide and stirring, heating, adding a catalyst I dropwise, and performing reaction, adding an alcohol amine, adding a catalyst II dropwise, and performing coupling while stirring; and separating a by-product from a product obtained after the coupling out, and purifying the product.
