Paragraph 0093-0105, (2018/11/21)
There is provided an economically advantageous manufacturing method capable of efficiently obtaining 1-chloro-2,3,3,3-tetrafluoropropene by using 1,2-dichloro-2,3,3,3-tetrafluoropropane as a raw material. A manufacturing method of 1-chloro-2,3,3,3-tetrafluoropropene is characterized in that it includes subjecting 1,2-dichloro-2,3,3,3-tetrafluoropropane to a dehydrochlorination reaction in a liquid phase in a presence of a base.

The relationship between 19F chemical shifts in halogenated propanes and their structures are elucidated using MNDO calculations to determine the population of rotamers.The pairs of atom gauche to a fluorine atom and van der Waals interaction between the two terminal substituents are responsible for the 19F chemical shifts.The differences among chemical shifts in diastereomers are also discussed in terms of the conformation of molecule.
