Claims14
A compound having the formula:
- wherein R1 is —CR5R6R7 or —CR5R6CR8R9R10;
- R2, R3 and R4 are each independently selected from halogen and hydrogen;
- and
- R5, R6, R7, R8, R9 and R10 are each independently selected from halogen and hydrogen, wherein at least one of R5, R6, R7, R8, R9 and R10 is halogen, and:
- wherein when R1 is —CR5R6CR8R9R10 and R8, R9 and R10 are each F, then at least one of R2, R3 and R4 is halogen;
- wherein when R1 is —CR5R6CR8R9R10 and R8, R9 and R10 are each F and when R2 is Br then one of R3 and R4 is halogen, or one of R5 and R6 is hydrogen;
- wherein when R1 is —CR5R6R7 and R5, R6, R7 are each F and R2 is Br, then R3 is halogen when R4 is selected from hydrogen or Br, or R3 is selected from hydrogen, Cl, Br or I when R4 is F;
- and
- wherein when R1 is —CR5R6R7 and R5, R6, R7 are each F and R2 is I, then R3 is halogen when R4 is hydrogen, or R3 is selected from hydrogen, F, Cl and I when R4 is F.
6 more elements
A fire extinguishing unit comprising a container and delivery system, the container containing a fire extinguishing compound according to the formula:
- wherein R1 is —CR5R6R7 or —CR5R6CR8R9R10;
- R2, R3 and R4 are each independently selected from halogen or hydrogen wherein at least one of R2, R3 and R4 must be halo;
- and
- R5, R6, R7, R8, R9 and R10 are each independently selected from halogen or hydrogen wherein at least one of R5, R6, R7, R8, R9 and R10 must be halogen;
- wherein when R1 is —CR5R6CR8R9R10 and R8, R9 and R10 are each F, then at least one of R3 and R4 is halogen when R2 is hydrogen, or R2 is Cl, F or I when R3 and R4 are both hydrogen;
- and
- wherein when R1 is —CR5R6R7 and R5, R6, R7 are each F then R2, R3 and R4 are each hydrogen or halogen, or when R2 is Br then R3 is selected from halogen and R4 is selected from hydrogen, Cl, F and I.
