摘要:
Method for improving plant growth by application of a mixture M comprising a component a) of a1) 20 to 96% by weight of sulfur, a2) 4 to 80% by weight of a complexing agent and, if appropriate, one or more crop protectants b) and/or additives c).
摘要:
In a chemical soil disinfestation method, a fungicidally, insecticidally or nematicidally active amount of a mixture M comprising a component a) of a1) 20 to 96% by weight of sulfur, a2) 4 to 80% by weight of a complexing agent and, if appropriate, one or more crop protection agents b) and/or additives c) is applied.
摘要:
The invention relates to a method for vulcanizing caoutchouc or latex by adding a mixture M which contains a component a) from a1) 20 to 96% by weight of sulfur, a2) 4 to 80% by weight of a complexing agent, and optionally other additives b) to caoutchouc or latex and then vulcanizing the mixture. The inventive method is characterized in that the average particle size of the primary particles of component a) ranges from 0.05 to 20 μm.
摘要:
Alkali metal salts of arabonic acid are manufactured by oxidizing D-hexoses in the presence of alkali metal compounds under specific conditions in respect of temperature, pressure, reaction time, sequence of addition of the individual reactants and mixing.The alkali metal salts of arabonic acid which may be manufactured by the process of the invention are valuable starting materials for the manufacture of vitamins, electro-coating assistants, crop protection agents and metal complexing agents.

摘要:
A process for the manufacture of N-[3,4-dimethylphenyl]-D-ribamine, in which(a) a mixture of 3,4-dimethylaniline and/or 3,4-dimethylnitrobenzene and a D-ribonic acid derivative of the formula ##STR1## where each R' is hydrogen or one of the R's together with R" is a single bond, R" is hydroxyl, R'" --O-- or, together with R', a single bond, and R'" is a hydrocarbon radical of 1 to 10 carbon atoms which may or may not be substituted by hydroxyl groups, or(b) D-ribonic acid 3,4-dimethylanilide is catalytically hydrogenated in an inert solvent at from above 100.degree. C. to 155.degree. C.
摘要:
Amines of the formula Ar--NH--CH.sub.2 --R, where Ar is unsubstituted or substituted phenyl and R is alkyl of 3 to 6 carbon atoms substituted by hydroxyl groups, are manufactured by catalytic hydrogenation of a salt of an acid of the formula R--COOH in the presence of (a) a compound of the formula Ar--Z, where Z is a nitro or reduced nitro group, and a strong acid or (b) a salt of an amine of the formula Ar--NH.sub.2 and a strong acid, in an organic solvent.
摘要:
The invention relates to a method for chemically decontaminating soil by applying a fungicidally, insecticidally or nematicidally active quantity of a mixture M containing a constituent a) consisting of a1) between 20 and 96 wt. % of sulphur and a2) between 4 and 80 wt. % of a complexing agent, and optionally at least one plant protecting agent b.) and/or additive c).
