    摘要: A method of preparing esters and salts of esters of pentavalent antimony from hydrated metal antimonates is disclosed. The method comprises heating a mixture of a hydrated metal antimonate and an organic compound selected from the group consisting of(i) a polyhydroxy or a polymercapto compound containing vicinal hydroxy or mercapto groups, or a mixture of the two groups,(ii) an alpha-hydroxy or alpha-mercapto carboxylic acid or thiocarboxylic acid, and(iii) glyoxal,To a temperature sufficient to form the salt of the ester. The salts which are prepared in this manner are effective flame retardants for cotton and other organic polymers.

    摘要: Finely divided particulate inorganic antimony compounds which are surface-modified with an organic zirconate having the formula(RO).sub.4 Zrwherein each R is independently an aliphatic radical containing from one to about 18 carbon atoms are described. These surface-modified antimony compounds may be incorporated into various organic resin and elastomer systems to improve the flame-retardant properties of these materials.
