Complexes of deprotonated hyaluronic acid with 3d metal ions of the 4th period of the Periodic Table and compositions containing these complexes as active ingredients or carriers. A process for the preparation of the complexes and compositions (pharmaceutical and cosmetic compositions) containing these complexes as active ingredients are disclosed in which zinc or cobalt (II) hyaluronate is preferably used as active ingredient.

Acaricidal compositions and process for preparing same

A Raney catalyst composition which has ice as a solid carrier. The reaction involving the Raney catalyst of the invention is carried out by portionwise adding a Raney catalyst containing ice as solid carrier to the reaction mixture. The operation-safe cylindrical or angular vessel used for the storage and/or handling of the Raney catalyst has a conical casing or side walls joining to the bottom through a bend radius of greater than 0.5 mm. The vessel is covered by a tightly closing cap.

Reliable Raney catalyst composition and vessel for containing same

The invention relates to a novel herbicide composition, which comprises the (S) enantiomer or racemate of a compound of the general formula (I), ##STR1## wherein R stands for a methyl or ethyl group, as active ingredient in an amount of 0.01 to 95% by weight together with one or more solid and/or liquid carrier(s), preferably grist(s) of native or synthetic material(s) and/or with inert solvents(s), preferably xylene(s) and/or cyclohexanone; and optionally with surface active agents(s), preferably anionic and/or nonionic emulsifying or dispersing agent(s). The invention further relates to the above compounds of the general formula (I) as well as to a process for the preparation thereof. The compounds according to the invention possess an outstanding herbicidal effect (over 90%) and advantageous selectivity threshold values against cultivated plants.

Novel herbicide composition

A herbicide composition, which comprises (S)-1'-methoxycarbonylethyl 2-bromo-5-(2-chloro-4-trifluoromethylphenoxy) benzoate or (S)-1'-ethoxycarbonylethyl 2-bromo-5-(2-chloro-4-trifluoromethylphenoxy)benzoate as active ingredient in an amount of 0.01 to 95.0% by weight together with one or more solid and/or liquid carriers, preferably grists of native or synthetic materials; and/or with inert solvents, preferably xylenes and/or cyclohexanone; and optionally with surface active agents, preferably anionic and/or nonionic emulsifying or dispersing agents.

Herbicide composition

The invention relates to new compounds of the general formulae (I) and/or (II), ##STR1## wherein R.sup.1 is a C.sub.1-6 alkyl or an aralkyl group, and

Trimethylsilylcarbamates and a process for the preparation thereof

A herbicidal composition capable of preventing weed growth of potatoes or soybean plants consists of a triazene or an aromatic nitro compound together with an inorganic salt, especially sodium bisulfate or potassium bisulfate which reduced the quantity of the organic herbicide below that usually required to obtain a corresponding herbicidal effect and hence prevents phytotoxic damage. The composition contains 0.1:1 to 15:1 parts by weight of the inorganic compound to the organic compound and is applied in an amount of 0.1 to 30 kg of the composition per hectare.
