| titleOfInvention | A kind of polyquaternium salt and its preparation method and application |
| abstract | The invention relates to a polyquaternary ammonium salt and its preparation method and application. The polyquaternary ammonium salt is a dendritic structure formed by alternating connection of the following two structural units; Wherein, A is an oxygen atom or a vacancy; R 1 , R 2 , R 3 , R 8 , and R 9 are each independently selected from C 6 -C 8 arylene groups, C 1 -C 8 straight chain alkylene groups, One of branched alkylene and C 1 -C 8 linear or branched alkylene hydroxy substituents; R 4 , R 5 , R 6 , and R 7 are each independently selected from C 1 -C 2 alkyl, X- is an anion. The polyquaternary ammonium salt of the invention can be used for sterilization and algae removal of reinjection water produced in oilfields or circulating cooling water of oil refineries and slime stripping of pipelines, and can also be used as a crude oil demulsification aid. |
