| titleOfInvention | Synthesis method of cyanide antidote |
| abstract | The invention relates to a synthesis method of a cyanide antidote, which comprises the steps of adding a formaldehyde solution and p-nitroanisole into an ethanol solution, regulating the pH value to be 4 by hydrochloric acid, heating, slowly adding iron powder, and reacting after the addition is finished to obtain 4-dimethylaminobenzoic ether; adding 4-dimethylaminobenzene into toluene, adding aluminum trichloride, heating for refluxing, removing methyl, cooling, adding saturated sodium bicarbonate solution, filtering off solid while hot, separating liquid, washing toluene phase with water, evaporating toluene under reduced pressure after separating liquid, and heating to evaporate product. The product obtained by curing of the invention has the purity of more than 99 percent and the yield of more than 80 percent; the method has the advantages of cheap and easily-obtained raw materials, no dangerous operation, less produced wastewater, less environmental pollution and high overall yield, and is suitable for large-scale production. |
