Casein pyrolysis was found to produce 2-nitropropane
, toluene, 4-methyl-pentanenitrile, ethylbenzene, and benzonitrile (Fig.
23-diamino-23-dimethylbutane (DDB) was prepared from 2-nitropropane
by half bromination to 23-dimethyl-23-dinitrobutane followed by reduction of nitro groups to amino groups with granules of tin and hydrochloric acid  the ether extract of diamine dried over anhydrous sodium sulphate was used.
The 11 solvents which would be precluded from landfill disposal are: benzene, carbon tetrachloride, chlorobenzene, cresols, MEK, trichloroethylene, 2-nitropropane
, nitrobenzene, pyridine, tetrachloroethylene and methylene chloride.
The VHAPs of Potential Concern and their de minimis usage levels are: dimethyl formamide (1.0 tons/year), formaldehyde (if used as a chemical reactant in a coating) (0.2 tons/years), methylene chloride (4.0 tons/year), 2-Nitropropane
(1.0 tons/year), Isophorone (0.7 tons/year), Styrene monomer (1.0 tons/year), Phenol (0.1 tons/year), Diethanolamine (5.0 tons/year), 2-Methoxyethanol (10.0 tons/year), 2-Ethoxyethyl acetate (5.0 tons/year).
