Latest Patents

One of Kalz's latest patents is titled "White modification of a bis-triazinyl amino stilbene optical brightener." This invention focuses on modifying the sodium salt of a known optical brightener to produce a white crystalline material. The process involves neutralizing the commercially available 4,4'-bis-(2-anilino-4-phenylamino-1,3,5-triazinyl-6-amino)-stilbene-2,2'-disulphonic acid with a sodium base and exposing it to elevated temperatures in an aqueous slurry. The addition of an electrolyte can inhibit the water solubility of the salt, allowing for recovery through spray drying.

Another significant patent is the "Process for the direct acetylation of aromatic amines." This disclosure details a method of reacting solid aromatic amines with liquid acetic anhydride to yield solid amides. The process ensures that the amine remains in a flowable particulate form and is agitated sufficiently to prevent agglomeration. The resulting amide is recovered by evaporating the acetic acid byproduct and any excess acetic anhydride.
