Abstract: This invention relates to a process for the production of dithiophosphoric acid poly-sulfide mixtures, which is characterized in that dithiophosphoric acid disulfides are reacted with sulfur at elevated temperatures. The dithiophosphoric acid polysulfide mixtures produced using the process according to the present invention are used as sulfur donors for the vulcanization of natural and synthetic rubbers and in the latex vulcanization of natural and synthetic rubber latex.

Abstract: Dithiophosphoric acids are advantageously produced by reaction of an alcohol or phenol with phosphorus sesquisulphide in the presence of sulphur, preferably at the reflux temperature of the alcohol used.

Abstract: Preparing O,O'-diesters of thiophosphoric acid, O-monoesters of thiophosphonic acid or thiophosphinic acids and their salts, from diesters of phosphorous acid, monoesters of phosphorous acids or phosphinous acids and sulphur in the presence of an aqueous solution of an auxiliary base. The solutions can be used in further syntheses or as extraction agent for cations.

Abstract: Amine salts of phosphorothioic acids, useful for example in lubricant compositions, are made by forming a mixture of sulphur and an amine, and then adding a phosphite ester. The reaction is controlled by the rate of addition of the ester.

Abstract: Dialky and trialky phosphites are reacted with sulfur. The resulting product is the desired lubricant additive which is mixed with suitable lubricating oils.

Abstract: A method for oxidizing organic compounds by contacting organic compounds with molecular oxygen in the presence of a noble metal pyrochlore having the formula:A.sub.2+x B.sub.2-x O.sub.7-ywherein A is a pyrochlore structure metal cation, and B is one or more of Ru, Rh, Ir, Os, and Pt; x and y are greater than or equal to 0 and less than or equal to 1.0, at a temperature up to about 200.degree. C.

Abstract: Liquid mixed triaryl thiophosphate mixtures can be prepared by forming a mixture of phenol and substituted phenols, forming a phosphite from that mixture and sulfurizing the phosphite, washing the thiophosphate with aqueous base, and drying the so washed thiophosphate under mild conditions. The products are liquid while containing at least 25 percent symmetrical triaryl thiophosphate. Colorless and odorless products are prepared.

Abstract: The invention relates to new 2,3,4-trinor-1,5-inter-m-phenylene-PGI.sub.2 derivatives of the formula (I) ##STR1## wherein A stands for carboxy, cyano, tetrazolyl or --COOR.sup.3 or --CONR.sup.1 R.sup.2 ;R.sup.3 is C.sub.1-4 alkyl or an equivalent of a pharmacologically acceptable cation:R.sup.1 and R.sup.2 each stands for hydrogen, phenyl; C.sub.1-5 alkyl, optionally substituted by carboxy, hydroxy, phenyl or C.sub.2-5 alkoxycarbonyl; or C.sub.1-4 alkylsulfonyl; orR.sup.1 and R.sup.2 together form an .alpha.,.omega.-alkylene chain containing 3-6 carbon atoms;B stands for oxygen or methylene;Y is optionally bromo-substituted vinylene or a --C.tbd.C-- group:R.sup.4 stands for hydrogen or tetrahydro-pyran-2-yl;R.sup.5 represents an alkyl group containing 5-9 carbon atoms, which can be optionally interrupted by one or more oxygen atom(s) or --CH.dbd.CH-- or --C.tbd.

Abstract: A dithiolphosphoric acid ester of the formula, ##STR1## wherein A is sec-butyl or tert-butyl group, and B is iso-propyl, n-butyl, iso-butyl, sec-butyl or tert-butyl group, which is useful as a soil pesticidal composition for pests in soil.
