| titleOfInvention | PROCEDURE FOR OBTAINING ALKALINE DERIVATIVES OF FOUR FOUR PRIMA METHYLENE DIANILINE .. |
| abstract | Process for obtaining alkaline derivatives of four four-methyl methylene dianiline, characterized in that an aqueous solution containing a sodium, lithium chloride, bromide, iodide or nitrite, or a mixture of said salts with four four-methyl methylene dianiline present is reacted in a slightly greater amount than the stoichiometric amount required to react with that amount of salt that is present in approximately more than twelve percent by weight of the solution, in a solvent having an appreciable degree of solubility for both water and water. Four four cousins methylene dianiline, at a temperature comprised approximately in the temperature range of twenty-five to ninety-five degrees centigrade; then separating the crystalline precipitate from the liquid phase.
