Preparation method of 1, 6-dihexyl triamine pentamethylenophosphonic acid

The invention relates to the technical field of chemical industry, in particular to a preparation method of dihexyl triamine pentamethylenophosphonic acid. The method comprises the steps of: (1) adding bishexamethylenetriamine and water into a reaction kettle, performing cooling to less than 25DEG, starting adding 31% hydrochloric acid dropwise to carry out salt-forming reaction for 2h; (2) adding phosphorous acid into the reaction kettle, performing heating to 80-110DEG C, and carrying out reaction for 3-8h; and (3) transferring all the materials into an elevated tank, adjusting the temperature of the reaction kettle to 120-150DEG C, adding the materials in the elevated tank dropwise into the reaction kettle slowly, and keeping the temperature in the reaction kettle at 120-150DEG C, and performing heat preservation for 2-3h at the end of dropwise adding. The method provided by the invention avoids the material-spraying phenomenon in the final distillation process, also can reduce the residual formaldehyde of the final product from 2-3% to 10mg/L, and the chloride from original 6-8% to 100mg/L.
