The invention discloses a lithium hexafluorophosphate synthesis technology with high reaction efficiency. The technology is characterized by: letting lithium fluoride anhydrous hydrogen fluoride solution from a blending tank pass through an intermediate tank and transferring the solution to a constant temperature mixing cooling kettle by a lithium fluoride anhydrous hydrogen fluoride solution intermediate pump, pumping the feed liquid in the mixing cooling kettle into a reaction tower feed inlet by a circulating absorption pump, performing atomization by an atomizing nozzle, then subjecting the processed feed liquid to full heat transfer and mass transfer with phosphorus pentafluoride gas from a phosphorus pentafluoride purification section, and carrying out synthetic reaction at a temperature at 0-10DEG C and under ordinary pressure, subjecting a little unreacted phosphorus pentafluoride gas to further reactive absorption by the lithium fluoride anhydrous hydrogen fluoride solution in a tail gas balance absorber, making the reacted solution enter the mixing cooling kettle to further participate in circulating absorption reaction. And the reaction tower, the tail gas balance absorber and the constant temperature mixing cooling kettle compose an airtight reaction system. The technology provided by the invention can realize continuous and automatic production, the production cost is low and the product consistency is good.
