A simple production process is provided of a perfluoroalkyl compound that uses monohydroperfluoroalkane as a starting material, the perfluoroalkyl compound being an important intermediate of organic electronic materials, medicine, agricultural chemicals, functional polymer materials and the like. With monohydroperfluoroalkane is reacted a base and then a carbonyl compound to produce an alcohol having a perfluoroalkyl group. For example, potassium hydroxide is made to interact with trifluoromethane, and a reaction with a carbonyl compound is induced to produce an alcohol having a trifluoromethyl group.

A method for purifying polybutylene terephthalate (PBT) includes: providing or receiving initial PBT, in which oligomers and tetrahydrofuran are present; dissolving the initial PBT in hexafluoroisopropanol (HFIP) to form a solution, in which the oligomers are also dissolved in the HFIP; and contacting the solution with compressed CO.sub.2 at a temperature and a pressure, thereby precipitating the purified PBT, resulting from a large portion of the oligomers are still dissolved in the HFIP, in the operation the temperature is in a range of 20 C. to 35 C., and the pressure is in a range of 900 psi to 1400 psi. A device for purifying PBT is also provided.
