摘要： This invention is directed to a method for mitigating HCl generation during 1230xa purification, which comprises the steps of; (a) adding a chelating agent into 1230xa crude, and (b) conducting the 1230xa purification in the presence of said chelating agent at a quantity sufficient to reduce or prevent 1230xa decomposition. Examples of chelating agent include tributyl phosphate (TBP), tripropyl phosphate (TPP), and triethyl phosphate (TEP). The concentration of chelating agent in 1230xa crude can range from 0.001 to 20 wt %, preferably from 0.01 to 10 wt %, and more preferably from 0.1 to 5 wt %.
