Abstract: In the process of the invention spent phosphoric acid is concentrated and stripped with air to a greater than 50% P.sub.2 O.sub.5 concentration to remove nitric acid. As a result of concentrating the spent acid a portion of the aluminum precipitates as monoaluminum phosphate, which is recovered by filtration. The filtrate is then ammoniated to produce a monoammonium phosphate solution. The solids precipitated during ammoniation and comprising aluminum ammonium phosphate which contains other metal phosphates are washed and reacted with aqueous ammonia to form diammonium phosphate.

Abstract: Reaction mixtures for forming curable epoxy resin compositions comprise an epoxy resin, a monoethylenically unsaturated monomer capable of forming polyacrylate rubber, a chain transfer agent to allow for higher levels of rubber in the curable epoxy resin without undesired viscosity increase and/or gellation, and a monomer soluble initiator. Optional ingredients include a crosslinking agent for the rubber-forming monomer, a grafting agent for rubber and epoxy resin, and an epoxy curing agent, preferably having activation conditions which are not satisfied when the initiator is activated. Heating the reaction mixture gives epoxy resin compositions containing polyacrylate rubber, the latter being optionally crosslinked and/or grafted to the epoxy resin. Activation of the curing agent, e.g., by heating, when such curing agent is present, yields cured adhesive compositions.

Abstract: A dispersed sulfur product having good flowability can be formed by dispersing particulate sulfur in a liquid poly(cis-isoprene) dispersion agent (i.e., either made by polymerizing synthetic cis-isoprene or by depolymerizing natural rubber). The sulfur product resulting therefrom has good dispersibility in rubber. The product can be formed without using an aqueous co-precipitation technique by simply mixing the liquid poly-(cis-isoprene) dispersion agent with a major amount of sulfur until the desired product results.

Abstract: A process for preparing substituted phthalic anhydrides, example 4-methylphthalic, in which the Diels-Alder addition product of a conjugated diene, example isoprene, and maleic anhydride is reacted with sulfur in the presence of a catalyst. The catalyst is zinc oxide and 2-mercaptobenzothiazole. This reaction is carried out at elevated temperatures. A resulting thio derivative by-product can further be reacted with water at elevated temperatures in the presence of catalytic amounts of a base to form 4-methylphthalic anhydride. This base can be sodium hydroxide or N,N,N', N'-tetramethylguanidine. o-Dichlorobenzene can be added to prevent solids distillation during the process.

Abstract: Triarylphosphates are prepared by phosphorylation of alkylphenols without use of phosphorylation catalyst. An improved phosphorylation step includes preheating alkylphenol feedstock to 150.degree. C. and completing reaction at 215.degree. C. or above in the presence of a stoichiometric excess of alkylphenol. The absence of phosphorylation catalyst simplifies distillative purification of reaction product by eliminating the need to withdraw purified product as distillate.
