    摘要: A process for preparing a low-dusting, free-flowing pigment which has not been subjected to any micronizing treatment comprising the steps of providing an inorganic pigment material; providing a source of water; forming a fine, well dispersed slurry of the pigment and water; milling the slurry; depositing a treating agent having the formula ROOCCHSO.sub.3 MCH.sub.2 COOR' wherein R and R' are monovalent alkyl radicals having from about 2 to about 20 carbon atoms, and M is a metallic monovalent cation on the slurried milled pigment; and drying the pigment material having a treating agent deposited thereon. The invention also provides the free-flowing pigments produced by this process.

    摘要: A catalyst for production of unsaturated aldehydes, such as methacrolein, by gas phase catalytic oxidation of olefins, such as isobutylene, contains oxides of molybdenum, bismuth, iron, cesium and, optionally, other metals. The catalyst has a certain relative amount ratio of cesium to bismuth, a certain relative amount ratio of iron to bismuth and a certain relative amount ratio of bismuth, iron, cesium and certain other metals to molybdenum and, optionally, tungsten. For a catalyst of the formula: Mo12BiaWbFecCodNieSbfCsgMghZniPjOx wherein a is 0.1 to 1.5, b is 0 to 4, c is 0.2 to 5.0, d is 0 to 9, e is 0 to 9, f is 0 to 2.0, g is from 0.4 to 1.5, h is 0 to 1.5, i is 0 to 2.0, j is 0 to 0.5 and x is determined by the valences of the other components, c:g=3.3-5.0, c:a=2.0-6.0 and (3a+3c+2d+2e+g+2h+2i)/(2×12+2b)=0.95-1.10.
