    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.
