Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Diethylenetriamine | HCID 8111 | — |
| Reactant | 2-((2-Nitrophenyl)azo)-4-(1,1,3,3-tetramethylbutyl)phenol | HCID 103927 | — |
| Solvent | O-Xylene | HCID 7237 | — |
| Product | Octrizole | HCID 62485 | 92% |
Reaction Steps
Example 1 is repeated, except that an equivalent amount of 2-nitro-2'-hydroxy-5'-tert.-octylazobenzene (93% pure) is used instead of 2-nitro-2'-hydroxy-5'-methylazobenzene and a mixture of 60 g of xylene and 40 g of diethylenetriamine instead of 80 g of xylene and 20 g of diethylenetriamine. The hydrogenation is carried out at 45° C. The title product is isolated in a yield of 92% of theory. Melting point: 101°-103° C.
