1-methyltrimethylenediamine Chemical Properties,Uses,Production

Description

1-methyltrimethylenediamine can be produced from crotonaldehyde by amination under hydrogenation conditions. Diamines with four to five carbon atoms are important intermediates for pharmaceuticals. However, the production of these diamines is restricted by the fact that the starting materials are difficult to obtain and that there is a strong tendency for cyclization during preparation.
