Claims12
A fluid composition comprising:
- (a) a compound of formula I:
- wherein R1 is linear C4 alkyl, and R2 is C1–C4 alkyl;
- and
- (b) a compound of formula II:
- wherein R1 is branched C4 alkyl, and R2 is C1–C4 alkyl;
- and R1 of formula I and R1 of formula II have an equal number of carbons, with formula I and formula II being present at a weight ratio of 3.5-100:1;
- and
- (c) a compound of formula III:
- wherein R1 is C4 alkyl, R2 is C1–C4 alkyl, and R3 is C1–C4 alkyl wherein the composition has:
- a) an initial boiling point of at least about 60° C., b) a flash point of at least 3° C., c) no more than 2.0 wt % halogen, d) a water content of less than or equal to about 1.0 wt. % e) a total acid content of less than or equal to 0.1 wt. %, and f) an evaporation rate of 0.1 to 12 relative to that of n-butyl acetate.
