  In the synthesis of 1,1,1,3,3-pentafluorobutane (R-365mfc), a mixture of R-365mfc and the impurity 1-chloro-3,3,3-trifluoropropene (R-1354zd) is purified and R-1354zd is removed from the mixture by contacting the mixture with 1-5 mols of chlorine for each mol of R-1354zd in the presence of ultraviolet light having a wavelength between about 300 to 400 nm which provides at least 0.02 watts-hour/kg of the mixture. The R-1354zd is reduced to below 10 wt. ppm as it is converted to 2,3-dichloro-1,1,1,3-tetrafluorobutane (R-354) or other butane containing more chlorine and having a higher boiling point than R-365mfc. The butane(s) may be separated more easily from R-365mfc. The photochlorination is effected in a manner such that at least about 96 weight percent of the starting amount of R-365mfc is maintained in the mixture.

  在合成 1,1,1,3,3-五氟丁烷（R-365mfc）的过程中，R-365mfc 和杂质 1-氯-3,3,3-三氟丙烯（R-1354zd）的混合物被提纯，R-1354zd 被从混合物中除去，方法是在波长介于约 300 至 400 纳米之间的紫外线存在下，每摩尔 R-1354zd 与 1-5 摩尔氯接触，可提供至少 0.02 瓦时/千克的混合物。当 R-1354zd 转化为 2,3-二氯-1,1,1,3-四氟丁烷（R-354）或其他含氯更多且沸点高于 R-365mfc 的丁烷时，其浓度会降至 10 wt.ppm 以下。这些丁烷可能更容易从 R-365mfc 中分离出来。光氯化的方式是在混合物中至少保持约 96 重量百分比的 R-365mfc 初始量。
