Claims2
A composition comprising:
- (A) 80 to 99.99% by mass of an asymmetric chain carbonate represented by Formula (3):
- R1OCOOR2 (3),
- wherein, in Formula (3), R1 is an organic group;
- and R2 is an organic group different from R1, and
- (B) at least one selected from the group consisting of symmetric chain carbonates represented by Formula (4):
- R1OCOOR1 (4),
- wherein, in Formula (4), R1 is as defined above;
- and
- symmetric chain carbonates represented by Formula (5):
- R2OCOOR2 (5),
- wherein, in Formula (5), R2 is as defined above, and
- (C) a halocarbonate ester compound represented by Formula (2):
- XCOOR2 (2)
- wherein, in Formula (2), X is a halogen atom, and R2 is as defined above;
- and
- wherein the asymmetric chain carbonate represented by Formula (3) is at least one selected from the group consisting of CF3OCOOCH3, CF3CH2OCOOCH3, CF3CF2OCOOCH3, CF3CF2CF2OCOOCH3, CF3CF(CF3)OCOOCH3, CF3CH(CF3)OCOOCH3, CF3CF(CH3)OCOOCH3, CF3CH(CH3)OCOOCH3, CF3OCOOCH2CH3, CF3CH2OCOOCH2CH3, CF3CF(CF3)OCOOCH2CH3, CF3CH(CF3)OCOOCH2CH3, CF3CF(CH3)OCOOCH2CH3, CF3CH(CH3)OCOOCH2CH3, CH3OCOOCFHCH3, and CH3CH2OCOOCFHCH3.
