摘要：
A liquid methylenedianiline product is disclosed. The product is produced by reacting aniline and ethylaniline with formaldehyde with an amine to formaldehyde ratio greater than about 2:1. The resulting reaction product is a liquid mixture of methylenedianiline, monoethyl methylenedianiline, and diethyl methylenedianiline having a viscosity of less than about 1000 cps at 40° C.
