Reaction Steps
This example demonstrates preparation of a chain extender having the inventive aromatic diamine as a minor proportion. The reaction time was shorter. A sample was prepared using a single equivalent of methyl disulfide (95.4 g) under similar reaction conditions and the reaction was completed in 16 hours. The product was predominantly mono(methylthio)-2,4-diaminotoluene containing a minority portion of di(methylthio)-2,4-diaminotoluene. A distilled fraction (b.p. 156-161 @ 1.0 mm) had the following analysis:
