Hexamethylenediamine → Hexamethylenediamine

Participants

Reaction Steps

14.6 Parts of 5-(3-t-butyl-2-hydroxy-5-methyl-phenyl)-5-methyl-hexanoic acid from Example 46 and 2.9 parts of hexamethylene diamine were heated at 150° C. for 24 hours. The solid obtained on cooling was crystallised from toluene and gave bis-5-(3-t-butyl-2-hydroxy-5-methyl-phenyl)-5-methyl-hexanoic acid amide of 1,6-diaminohexane m.p. 139°-42° C. with the following percentage composition by weight.
