摘要: A bismuth oxide/chromium oxide mixed phase pigment having the composition Bi.sub.2-x Cr.sub.x O.sub.3 wherein 0.05.times.0.5 and a specification surface of about 1.0 to 10 m.sup.2 /g is produced by mixing metallic bismuth intensively with a chromium (III) and/or chromium (VI) compound, calcining the homogeneous mixture in an oxidizing atmosphere at a temperature of about 500.degree. to 800.degree. C., and crushing the product to pigment size.

摘要: A process for scrubbing acid gases, especially carbon dioxide, from gas mixtures with an aqueous amine solution serving as the scrubbing liquid in which hexamethylene diamine serves as the amine. The concentration of the hexamethylene diamine in the aqueous solution is 5 to 40% by weight, preferably 25 to 35% by weight.
