Diisobutylamine synthesis
- Product Name:Diisobutylamine
- CAS Number:110-96-3
- Molecular formula:C8H19N
- Molecular Weight:129.24
As with other secondary amines, diisobutylamine can be nitrosated to form the highly toxic (Olah 1975) N-nitrosodiisobutylamine (Guttenplan 1987; Vlasenko et al 1981; Spiegeholder et al 1978). Thus, nitrosation of commercial preparations of diisobutylamine occurs on standing, presumably by reaction with nitrogen oxides in the air (Spiegelhalder et al 1978) and N-nitrosodiisobutylamine has been found in various fishery products (Kawabata et al 1974) and other foods (Osborne 1972; Telling 1972).
Yield:110-96-3 98% ,6898-82-4 2%
Reaction Conditions:
with hydrogen at 220;
Steps:
Hydrogenation of iso-butyronitrile (1a)
The conditionalresidence time of hydrogen was 40 s kgcat mol-1,and that of nitrile 1a, 119 s kgcat mol-1. The reaction wasperformed at 220°C. The conversion of nitrile 1a was100%. The selectivity with respect to di-iso-butylamine4a was 98%, and its yield, 98%. Mass spectrum (EI,70 eV), m/e ((Irel, %): 130.0 (16) [M + 1], 128.7 (2) [M],86.0 (100), 57.0 (30), 41.0 (30), 44.0 (19), 42.1 (10).The selectivity with respect to N-iso-butylidene-isobutylamine3a was 2%, and its yield, 2%. Mass spectrum(EI, 70 eV), m/e (Irel, %): 128.0 (34) [M + 1], 126.8 (6)[M], 84.0 (100), 41.0 (57), 56.9 (51), 56.0 (40), 42.0(26), 70.0 (10)
