    摘要: Methods of producing ABO.sub.3 compounds in which A represents a first metal ion and B represents a second metal ion from mixed metal coordination complexes are disclosed. The methods involve reacting compounds serving as a source of the B metal ion with a substituted aromatic compound, in solution, and thereafter reacting the metal coordination complex formed with a compound serving as a source of the A metal, in solution. An example is the reaction of titanium tetraisopropoxide with catechol to form a titanium catecholate coordination complex which is thereafter reacted with barium hydroxide octahydrate to form a pentamethanol barium triscatecholatotitanate mixed metal coordination complex which can be calcined at elevated temperatures to produce the ABO.sub.3 compound, barium titanate (BaTiO.sub.3), which is known to have outstanding dielectric, ferroelectric and piezoelectric properties. Portions of the A and/or B ions can be substituted with other metals.

    摘要: Certain tetrahydrocarbylphosphonium bicarbonate salts are produced by reacting a trihydrocarbyl(hydrocarbylcarboxymethyl)phosphonium hydroxide inner salt with water. For example, methyl tri-n-butylphosphonium bicarbonate salt was prepared in quantitative yields by heating tri-n-butylcarboxymethylphosphonium hydroxide inner salt in an aqueous methanol solution at 100.degree. C. for 3 hours.

    摘要: Compounds of formulas I and II are heat-activated catalysts used in making polyurethanes. ##STR1## wherein R, R.sub.1, and R.sub.2 are each independently H, hydrocarbyl or an inertly-substituted hydrocarbyl; R.sub.3 and R.sub.4 are each independently hydrocarbyl or an inertly-substituted hydrocarbyl; and X is an anion. Upon heating, Compounds I and II catalyze the reaction and may release gaseous by-products which cause the resulting polyurethane compound to foam. For example, the catalyst, t-butyl imidazole-N-carboxylate, when heated to 120.degree. C., catalyzes the reaction between a polyol and a polyisocyanate to give a foamed polyurethane which cured in 16 minutes.

    摘要: Ar-cyclic sulfonium arenethiol salts exemplified by the formula: ##STR1## may be converted to their corresponding zwitterion, exemplified by the formula: ##STR2## The latter polymerize very readily upon exposure to mild conditions of heat or radiative energy. The resultant polymers are water-insoluble resins useful as adhesives, coatings, films and the like. The zwitterions containing more than one arenesulfide and cyclic sulfonium group per molecule, crosslink upon exposure to heat to form thermoset resins.
