High-purity octafluorocyclobutane rectification system

The high-purity octafluorocyclobutane rectification system comprises an octafluoro separation tower, an octafluoro rectification tower, an octafluoro detection tank and a molecular sieve adsorber, the input end of the octafluoro separation tower is communicated with a crude octafluoro conveying pipe, a second separation output end is arranged at the top of the octafluoro separation tower, and a second separation output end is arranged at the bottom of the octafluoro rectification tower. The input end of the octafluoro rectifying tower is communicated with the second separation output end; a second rectification output end is arranged at the top of the octafluoro rectification tower. The octafluoro detection tank is communicated with the second rectification output end and is provided with a finished product output end, and the finished product output end is communicated with the octafluoro finished product tank through a second pump body. The input end of the molecular sieve adsorber is communicated with the
