    摘要: The present disclosure is concerned with aqueous dispersions of anionic acid dyes, especially the monosulphonated level dyeing acid dyes, which have low room temperature, low shear viscosities and good storage stability. This low viscosity enables them to be readily poured, pumped and otherwise handled. These dispersions comprise dyestuff solids with a controlled particle size distribution having a median value between about 1 and 10 microns; an anionic dispersant; and an electrolyte. In a preferred embodiment the pH is adjusted to give an optimum viscosity value. Another preferred feature is the adjustment of the rheology with a thickening agent such as xanthan gum. These dispersions find particular utility in the continuous dyeing of carpet, especially in Kuesters or foam dyeing equipment.

    摘要: The present invention is concerned with the modification of the sodium salt of a known optical brightener to obtain a white crystalline material. The commercially available 4,4'-bis-(2-anilino-4-phenylamino-1,3,5-triazinyl-6-amino)-stilbene-2,2'-disulphonic acid is neutralized with a sodium base such as caustic and exposed to temperatures above about 65.degree. C. as an aqueous slurry containing some undissolved disodium salt. The water solubility of this salt may be inhibited by the addition of an electrolyte and the product may be recovered by spray drying.

    摘要: The present disclosure is concerned with a process of reacting a solid aromatic amine with liquid acetic anhydride to yield a solid amide. The amine is in a flowable particulate form and it is subject to sufficient agitation during the reaction to prevent agglomeration. The amide is recovered as a flowable particulate by evaporation of the acetic acid by product and any excess acetic anhydride.
