Abstract: An improved process for making a bismuth carboxylate is disclosed which generally comprises (A) heating an anhydrous reaction mixture comprising a carboxylic acid or anhydride, bismuth metal, and hydrazine to a temperature of from about 80.degree. C. up to, but not including, the temperature of decomposition of any reactant, hydrazine, or the desired bismuth carboxylate, (B) bubbling an oxygen-containing gas through the reaction mixture during (A), and (C) removing water formed during (B) from the reaction mixture. Bismuth carboxylate compositions are also disclosed which contain at least 70 equivalents of a bismuth carboxylate derived from at least one carboxylic acid or anhydride having from about 6 to about 20 carbon atoms, the composition having a viscosity of not more than 1000 centipoise at 25.degree. C.

Abstract: Antimony mercaptide esters of the formula ##STR1## are provided. The preparation of such esters comprises reacting an antimony oxide compound with a mercapto alcohol in a first reaction to form an antimony mercaptide intermediate. The intermediate is then reacted with an organic acid or the anhydride thereof in a second reaction to form the antimony mercaptide ester.

Abstract: A bismuth-containing product in the form of a powder easily dispersible in water to form a colloidal solution suitable for oral administration as an antiulcer drug is obtained from an aqueous solution of potassium citrate, bismuth citrate and potassium hydroxide, the product being precipitated from the aqueous solution by dilution with acetone.

Abstract: Species-linked diamine triacetic acids of the formula ##STR1## wherein T is an organic species containing at least one amine, hydroxyl, or thiol functional group, L is the residue of at least one of those functional groups and R is a two or more atom long covalent bridge, are disclosed. Methods for their preparation, for the preparation of metal chelates from them and for the use of the chelates are also disclosed. In a preferred embodiment, the metal ions employed in the formation of the chelates are rare earth metal ions capable of forming fluorescent chelates which can in turn be employed in fluoroassay techniques.

Abstract: Antimony trioxide is reached with an organic mercaptan R.sup.1 --SH or R.sup.2 --OCO--(CH.sub.2).sub.n --SH (where R.sup.1 is an alkyl, alkenyl, aryl, aralkyl, cycloalkyl or heterocyclic group having from 1 to 18 carbon atoms, which optionally has sulfide bond or ether bond or a hydroxyl or carboxyl group as a substituent, R.sup.2 is a hydrogen atom or an alkyl, alkenyl, aryol, aralkyl, cycloalkyl or heterochclic group having from 1 to 18 carbon atoms, which optionally has sulfide bond or ether bond or a hydroxyl or carboxyl group as a substituent, and n is 1 to 3) in the presence of a lower aliphatic carboxylic acid to give an antimony mercaptide Sb(--SR.sup.1).sub.3 or Sb(--S--(CH.sub.2).sub.n --COOR.sup.2).sub.3 of high purity with high yield. The products are excellent in the time-dependent stability and the effect as a passivator for catalysts for catalytic cracking of hydrocarbons.

Abstract: A method for isolating a vinyl salt compound in solid form from an aqueous solution thereof by spray drying such an aqueous salt solution.

Abstract: Novel organic water-soluble antimony compounds are prepared by reacting an alkoxyalkylamine with a hydroxycarboxylic acid to form an intermediate product and then reacting the intermediate product with an antimony oxide. These compounds are useful for use as catalyst metal poison passivators.

Abstract: Novel organic water-soluble antimony compounds are prepared by reacting ammonia or an alkylamine with a hydroxycarboxylic acid to form an intermediate product and then reacting the intermediate product with an antimony oxide. These compounds are useful for use as catalyst metal poison passivators.

Abstract: Novel organic water-soluble antimony compounds are prepared by reacting an alkanolamine with a hydroxycarboxylic acid to form an intermediate product and then reacting the intermediate product with an antimony oxide. These compounds are useful for use as catalyst metal poison passivators.
