A solvent composition comprising:
- 1,2-dichloro-3,3-difluoro-1-propene,
- wherein the 1,2-dichloro-3,3-difluoro-1-propene contains both of cis-1,2-dichloro-3,3-difluoro-1-propene and trans-1,2-dichloro-3,3-difluoro-1-propene,
- and wherein a molar ratio of the cis-1,2-dichloro-3,3-difluoro-1-propene to the trans-1,2-dichloro-3,3-difluoro-1-propene in the solvent is 50.00:50.00 to 99.99:0.01.
