Abstract
The present application provides compositions comprising 1,2-dichloro-1,2 -difluoroethylene (i.e., CFO-1112) and an additional component. The present application further provides use of the compositions provided herein in fire suppression applications (e.g., total flooding and/or streaming fire suppression applications).
Claims16
A process for extinguishing or suppressing a flame, comprising dispensing at the flame a composition comprising:
- i) 1,2-dichloro-1,2-difluoroethylene;
- and
- ii) a compound selected from R-1336mzzZ, R-1336mzzE, R-1233xfB, R-1438mzzE, R-1438mzzZ, R-1224ydZ, R-1224ydE, R-1336yf, R-125, R-227ea, R-236fa, R-1225yeE, R-1225yeZ, 1,1,1,2,2,4,5,5,5-nonafluoro-4-(trifluoromethyl)pentan-3-one, water, carbon dioxide, nitrogen, and argon;
- in a concentration sufficient to extinguish or suppress the flame.
2-19. (canceled)
A method of reducing the flammability of a fluid, comprising contacting the fluid with a composition comprising:
- i) 1,2-dichloro-1,2-difluoroethylene;
- and
- ii) a compound selected from R-1336mzzZ, R-1336mzzE, R-1233xfB, R-1438mzzE, R-1438mzzZ, R-1224ydZ, R-1224ydE, R-1336yf, R-125, R-227ea, R-236fa, R-1225yeE, R-1225yeZ, 1,1,1,2,2,4,5,5,5-nonafluoro-4-(trifluoromethyl)pentan-3-one, water, carbon dioxide, nitrogen, and argon;
- in a concentration sufficient to reduce the flammability of the fluid.
A method of extinguishing or suppressing a fire, comprising:
- (a) providing a composition comprising:
- i) 1,2-dichloro-1,2-difluoroethylene;
- and
- ii) a compound selected from R-1336mzzZ, R-1336mzzE, R-1233xfB, R-1438mzzE, R-1438mzzZ, R-1224ydZ, R-1224ydE, R-1336yf, R-125, R-227ea, R-236fa, R-1225yeE, R-1225yeZ, 1,1,1,2,2,4,5,5,5-nonafluoro-4-(trifluoromethyl)pentan-3-one, water, carbon dioxide, nitrogen, and argon;
- (b) disposing the composition in a pressurized discharge system;
- and
- (c) discharging the composition into an area to extinguish or suppress the fire in that area.
A method of inerting an area to reduce or prevent occurrence of a fire, explosion, or combination thereof, in the area, the method comprising:
- (a) providing a composition comprising:
- i) 1,2-dichloro-1,2-difluoroethylene;
- and
- ii) a compound selected from R-1336mzzZ, R-1336mzzE, R-1233xfB, R-1438mzzE, R-1438mzzZ, R-1224ydZ, R-1224ydE, R-1336yf, R-125, R-227ea, R-236fa, R-1225yeE, R-1225yeZ, 1,1,1,2,2,4,5,5,5-nonafluoro-4-(trifluoromethyl)pentan-3-one, water, carbon dioxide, nitrogen, and argon;
- (b) disposing the composition in a pressurized discharge system;
- and
- (c) discharging the composition into the area to reduce or prevent the fire, explosion, or combination thereof from occurring.
A fire suppression apparatus or system comprising a composition comprising:
- i) 1,2-dichloro-1,2-difluoroethylene;
