| 摘要 |
The invention provides novel mixtures of at least two aminoalkanols of the formula: <IMAGE> wherein R1 and R2 each represent a C1-21 alkyl and the sum of the carbon atoms in R1 and R2 is 6 to 22; and the R1-CH-CH-R2 units are mixtures containing 8 to 24 carbon atoms of at least two compounds. The vicinal OH and NH2 substituents are uniformly distributed statistically along the chain. The mixtures are readily prepared from mixtures of C8-C24 olefins by epoxidation followed by reaction with ammonia. The mixtures are useful as intermediates in the production of hydroxyalkyl-aminobutyric acid mixtures for lubricating the cold working of aluminum and as corrosion inhibitors for corrodible iron-containing metals.
