Abstract: 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.

Abstract: Finely divided particulate inorganic antimony compounds which are surface modified with an organic titanium compound having the formulaTi(OR).sub.4wherein each R is independently an alkyl, aryl, cycloalkyl, or vinyl group containing from one to about 18 carbon atoms, orTi(OR').sub.2 (OYX).sub.2wherein X is oxygen or nitrogen, Y is a two- or three-carbon atom chain, and R' is equal to R, H or the ligand represented by XYOH 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.

Abstract: 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.

Abstract: Finely divided particulate inorganic antimony compounds which are surface modified with up to about 5% by weight of an organosilane having the formula ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 are each independently hydrogen, lower alkyl, lower alkenyl, alkoxyalkyl aryl, lower alkylaryl, or lower arylalkyl groups, and R' is an organo functional group 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.

Abstract: Bright zinc deposits are obtained from an acid bath containing a carboxy terminated anionic wetting agent and a brightener comprising a heterocyclic compound selected from the group consisting of furans, thiophenes and thiazoles.

Abstract: Organic dyes or dye intermediates are crystallizable in an aqueous medium in the presence of finely divided, solid polytetrafluoroethylene (hereinafter referred to as "PTFE") resin particles. Crystals of desirable, very small size are precipitated more quickly than with conventional seeding. This process is particularly useful for crystallizing disperse dyes of two types:1. azo dyes formed by coupling a diazonium salt with a substituted aromatic amine, and2. anthraquinone dyes formed by condensing a nitroanthraquinone compound with an aromatic amine.
