Embodiment 1
[0029] Take 28.56 g (0.24 mol) of benzotriazole and dissolve it with 100 ml of distilled water. Add 12 g of NaOH (0.3 mol), stir and heat. Dissolve NaOH completely, add 22.16g (0.24mol) of n-chlorobutane, increase stirring, keep the reaction temperature at 60-80°C, react for 20 hours, distill the solvent, wash the excess benzotriazole with heated water, separate It is the water layer and the oil layer, and the water layer is separated to obtain the oil layer, and then dried with calcium chloride to obtain 20.9 g of the intermediate product N-n-butylbenzotriazole.
[0030] Take 10.79g (0.06mol) of the intermediate product N-n-butyl benzotriazole, use 70ml of distilled water as a solvent, add it to a four-necked flask, control the temperature at 50°C, and add 22.68g (0.18mol) of dimethyl sulfate , stirred and reacted for 3 hours to obtain 33.2 g of n-butyl benzotriazole cationic compound.
Embodiment 2
[0032] Take 28.56 g (0.24 mol) of benzotriazole and dissolve it with 100 ml of distilled water. Add 16.8 g of KOH (0.3 mol), stir and heat. KOH is completely dissolved, add 29.7g (0.20mol) of chloro-n-octane, increase stirring, and keep the reaction temperature at 60-80°C. After reacting for 20 hours, distill the solvent, wash the excess benzotriazole with heated water, and separate It is the water layer and the oil layer, and the water layer is separated to obtain the oil layer, and then dried with calcium chloride to obtain 37.6 g of the intermediate product N-n-octylbenzotriazole.
[0033] Take 13.86g (0.06mol) of the intermediate product N-octylbenzotriazole, use 70ml of absolute ethanol as a solvent, add it to a four-necked flask, control the temperature at 50°C, and add 16.65g (0.18mol) of epichlorohydrin mol), stirred and reacted for 3 hours to obtain 28.4 g of n-octylbenzotriazole cationic compound.
Embodiment 3
[0035] Take 28.56 g (0.24 mol) of benzotriazole and dissolve it with 100 ml of distilled water. Add 20.4g of CH 3 CH 2 ONa (0.3mol), stirred and heated. CH 3 CH 2 ONa was completely dissolved, added 53.2 g (0.26 mol) of chlorododecane, increased stirring, and kept the reaction temperature at 60-80 ° C. After reacting for 24 hours, the solvent was distilled, and excess benzotriazole was washed with heated water, and separated It is the water layer and the oil layer, and the water layer is separated to obtain the oil layer, and then dried with calcium chloride to obtain 52.45 g of the intermediate product N-dodecylbenzotriazole.
[0036] Take 17.60 g (0.06 mol) of the intermediate product N-dodecylbenzotriazole, use 70 ml of distilled water as a solvent, add it to a four-necked flask, control the temperature at 50 ° C, add 11.39 g (0.09 mol) of benzyl chloride, The reaction was stirred for 3 hours to obtain 26.51 g of dodecylbenzotriazole cationic compound.
