| titleOfInvention | A kind of renewable organic amine fume desulfurizing agent and preparation method thereof |
| abstract | The present invention relates to a kind of renewable organic amine fume desulfurizing agent and preparation method thereof.This fume desulfurizing agent is the aqueous solution of 1-(2-ethoxy)-4-(2-hydroxypropyl) piperazine sulfate.The preparation manipulation step of this fume desulfurizing agent is: first prepare 1-(2-ethoxy)-4-(2-hydroxypropyl) piperazine, in sulfuric acid solution, slowly add 1-(2-ethoxy)-4-(2-hydroxypropyl) piperazine, dissolve and obtain the aqueous solution of 1-(2-ethoxy)-4-(2-hydroxypropyl) piperazine sulfate completely.The present invention is solvent-free participation in building-up process, and reaction products therefrom is without the need to being separated solvent, and building-up process is simple, and mild condition, adds moderate amount of sulfuric acid at normal temperatures and mix with water and obtain desulfurizing agent; This fume desulfurizing agent remains liquid state more than 0 DEG C, and temperature in process of production slightly can not Crystallization Plugging pipeline in low environment. |
