- Triazine natural gas drag reducer as well as synthesis method and application thereof
-
The invention discloses a triazine natural gas drag reducer and a synthesis method thereof. The molecular structural formula of the drag reducer is shown in the description. The synthesis method of the drag reducer comprises the following steps: dissolving cyanuric chloride in a solvent, dropwise adding an alcohol and an inorganic alkali at -15-0 DEG C, carrying out a reaction at -15-0 DEG C for 2-6 h, adding morpholine and the inorganic alkali after the reaction ends, carrying out a reaction at 50-100 DEG C for 6-12 h, washing the obtained reaction product with water after the reaction ends,and drying the washed reaction product to obtain the product. The drag reducer has a multi-polar end and a non-polar end, and has a good adsorption performance and excellent drag reducing and transportation increasing effects. The synthesis method has the advantages of simplicity, mild conditions, short time, low device requirements, and easiness in realization of large-scale industrial production.
