| abstract | 319,808. Kolloidchemie Studienges., Carpzow, J. B., March M., Lenzmann, R., and Sanders, H. May 30, 1928. Body colours or pigments are made by bring- ing dyestuffs into intimate contact with salt- or fresh-water mud containing at least 20 per cent of unsaturated colloidal compounds, stated to be unsaturated silicon compounds, in the naturally moist or still reactive state, in the presence of metal salts which can form silicates with the unsaturated colloidal constituents of the mud, such as salts of aluminium, magnesium, calcium, barium, iron or copper, or by forming the dyestuffs from their components in the presence of such a mud. The colloidal constituents may be separated from the mud by washing or centrifuging, and may be allowed to stand for some time in a state of suspension, in the absence of air, with or without the addition of bacteria foods and anaerobic bacteria cultures, in order to in-- crease their activity. In examples, (1) fuchsine is treated with alum in the presence of mud of the character described, (2) crude aniline or a mixture of aniline and tolidine is mixed with the mud, dried, and oxidized by air or other oxidizing agents such as nitric acid or hydrogen peroxide; blue-red to white-red body colcurs are formed. |
