ABSTRACT:
This invention relates to an improved process for storing and transporting toluenediamine, particularly for long term storage or storage in large containers, e.g., shipboard containers. The improvement in the process resides in substantially reducing the melting or freezing point of anhydrous toluenediamine obtained by the fractional distillation of a reaction product generated by the hydrogenation of dinitrotoluene. Such melting point reduction is accomplished by maintaining a water concentration in the toluenediamine in an amount of from 5 to 15% by weight under molten conditions for storage and transport. Preferably the level of water maintained in the toluenediamine is from about 7 to 10% by weight.
