  • Process for the production of phenolic complexes of hexamethylenetetramine
    Patent number: 4069220
    Abstract: A process has been developed for producing complexes of phenol or phenolic compounds and hexamethylenetetramine by mixing the ingredients with only enough water, or other suitable solvent, to promote the reaction. Heat liberated by the reaction is controlled by cooling the mixing chamber, and drying is accomplished by removing the small amount of solvent in conventional type dryers.

  • Process for producing salts of hexamethylenetetramine
    Patent number: 3936451
    Abstract: A process for producing a salt of hexamethylenetetramine (hexa), such as the tolulene sulfonic acid (TSA) - hexa salt, by mixing an acid with hexamethylenetetramine and only enough solvent such as water to promote the reaction. Excess heat liberated by the reaction is controlled by cooling the mixing chamber and drying is accomplished in a heated or ambient atmosphere except for hygroscopic salts which are easily dried in a vacuum or may be dried in a very dry atmosphere.
