Embodiment 1
[0025] The synthetic technique of a kind of organic polymer flocculant that the present invention relates to comprises the following steps:
[0026] (a) Measure a certain amount of polyacrylamide, formaldehyde, dimethylamine, and hydrochloric acid for subsequent use. In terms of mass percentage, hydrochloric acid accounts for 1.0% of the total amount;
[0027] (b) Formaldehyde is placed in the reaction vessel;
[0028] (c) slowly add polyacrylamide and catalyst in reaction vessel, stir while adding;
[0029] (d) Then, the reaction vessel is placed in a water bath to be heated;
[0030] (e) Next, add dimethylamine in the reaction vessel;
[0031] (f) cooling, then adding hydrochloric acid quaternization;
[0032] (g) Finally, the target product is obtained through evaporation, concentration and filtration.
[0033] Because in the synthesis process of organic polymer flocculant, the concentration of hydrochloric acid has a great influence on the conversion rate of synthesis ...
Embodiment 2
[0036] The only difference between this embodiment and embodiment 1 is that in this embodiment, hydrochloric acid accounts for 0.8% of the total amount in terms of mass percentage, and the other parts of this embodiment are the same as embodiment 1, and will not be repeated.
Embodiment 3
[0038] The only difference between this embodiment and embodiment 1 is that in this implementation, in terms of mass percentage, hydrochloric acid accounts for 1.2% of the total amount, and other parts of this embodiment are the same as embodiment 1, and will not be repeated.
