Abstract: The use as an activator for a chemical blowing agent, or as an accelerator or activator in the vulcanization of rubber, of a reaction product of urea and an oxide, carbonate or hydroxide of zinc, cadmium, calcium or lead, which reaction product may be optionally solvated, and certain such products per se.

Abstract: The invention provides compounds of formula I ##STR1## in which X, R.sup.1, R.sup.2 and R.sup.3 are as defined in the description. The compounds have valuable fungicidal activity.

Abstract: The invention provides novel herbicidal sulphonanilides of the formula: ##STR1## where R.sup.1 -R.sup.8 have the meanings given in the specification, and salts thereof, processes for their preparation, and herbicidal compositions containing them.

Abstract: Chemical dispensing apparatus for emptying and rinsing containers of chemicals, with dilution of chemical. The apparatus includes a chamber in which the container can be enclosed and supported, draining means provided at a lower portion of said chamber and a hollow perforated wash pipe mounted on the chamber so as to be moveable into the interior thereof to pierce twice any container supported therein, the wash pipe being connected to a diluent supply. The chamber is provided with means for supporting the container in a generally tilted manner such that a corner thereof is presented as the lowest portion and the wash pipe is arranged to pierce the container through said corner, means being provided on the wash pipe to hold apart the lowest pierced portion of the container and one or more nozzles being provided to spray diluent over a substantial part of the interior of the container while the pierced portion is held apart.

Abstract: Compounds of the formula: ##STR1## where: A is oxygen or sulphur;R.sup.1 is phenyl or substituted phenyl in which the substituent is at least one member selected from the group consisting of halogen, C.sub.1-6 -alkyl, C.sub.1-6 -haloalkyl, C.sub.1-6 -alkoxy, C.sub.1-6 -haloalkoxy and nitro;R.sup.2 is 1-imidazolyl or 1,2,4-triazol-1-yl; andR.sup.3, R.sup.4, R.sup.5 and R.sup.6, which may be the same or different, are each hydrogen, halo, C.sub.1-6 -alkyl or C.sub.1-6 -alkoxy have valuable fungicidal properties.

Abstract: There are described new pyrimidine derivatives of the general formula I ##STR1## in which n is 0, 1 or 2;R.sub.1 is(a) the group --CXR.sub.5, where X is oxygen or sulphur and R.sub.5 is hydrogen, a nitrogen or sulphur containing heterocyclic group, which can contain other hetero atoms, optionally substituted alkenyl, acyl, alkoxycarbonyl, alkyl substituted by aryloxy, or optionally substituted mono- or dialkylamino; or R.sub.5 is the group --NHR.sub.6, where R.sub.6 is substituted amino, substituted carbamoyl, optionally substituted alkylsulphonyl, acyl or arylsulphonyl, and when n is 0 or when X is sulphur, R.sub.5 can also be alkyl, haloalkyl, aryl, aralkyl, alkoxycarbonylalkyl or arylamino;(b) cyano or the group --CXYR.sub.7, where X and Y are the same or different and are oxygen, sulphur or optionally substituted imino and R.sub.

Abstract: Compounds are disclosed having fungicidal activity and are of general formula I ##STR1## where at least three of A, C, D and E are --CX.dbd. and the other is --CX.dbd. or --N.dbd., where X is hydrogen, C.sub.1-8 -alkyl (optionally substituted by halogen), halo, nitro or phenoxy, in which the phenyl is optionally substituted by one or more groups selected from halo and trifluoromethyl;R.sup.1 is --SO.sub.2 R.sup.3 or ##STR2## and R.sup.2 is ##STR3## where R.sup.6 is hydrogen, C.sub.1-8 -alkyl (optionally substituted by one or more groups selected from halogen and hydroxy), C.sub.1-8 -alkanoyl, benzoyl, cyclohexylcarbonyl or aminocarbonyl (in which the amino is substituted by benzoyl or chlorobenzenesulphonyl);R.sup.3, R.sup.4, and R.sup.5 may be the same or different and have the meanings given to R.sup.6 or can be di-C.sub.1-8 -alkylamino; and Z is oxygen or sulphur; and when R.sup.1 is ##STR4## R.sup.2 can also be --CN.

Abstract: Compounds of any of one of formulae I-VII ##STR1## where is a single or double bond;A is oxygen or sulphur;R.sup.1 is aryl;R.sup.2 is 1-imidazolyl or 1,2,4-triazol-1-yl; andR.sup.3, R.sup.4, R.sup.5 and R.sup.6, which may be the same or different, are each hydrogen, halo, alkyl or alkoxy, have fungicidal activity.
