The invention relates to a method for producing a master batch comprising between 0.01 and 50 wt. % of carbonaceous nanofillers and at least one sulphurated material such as elemental sulphur by melt compounding, and to the master batch thus produced and the different uses thereof. The invention also relates to a solid composition comprising carbonaceous nanofillers dispersed in a sulphurated material.

Production of a master batch based on sulphur and carbonaceous nanofillers, the master batch produced, and uses thereof

The present invention relates to a process for the preparation of bis(dimercaptothiadiazole) (or bis-DMTD), more particularly of 5,5'-dithiobis(1,3,4-thiadiazole-2-thiol), said process being carried out in a single reactor and making possible a preparation with improved yields which is more respectful of the environment.

Process for the preparation of bis-DMTD

The present invention relates to the field of vulcanization of unsaturated polymers, in particular halogenated, and more particularly chlorinated, unsaturated polymers, such as, for example, polychloroprene, using as vulcanization agent a mixture of bis(2,5-dimercapto-1,3,4-thiadiazole) and at least one organic base. The present invention relates to the process for vulcanization of said polymers with said vulcanization mixture.

Vulcanization composition for unsaturated polymers

The invention relates to a method for preparing lactames, according to which a photonitrosation of a cycloalkane is carried out using nitrosyl chloride (NOCI). According to the invention, said photonitrosation is carried out by means of LEDs emitting a monochromatic light. The method according to the invention can also include a step comprising Beckmann transposition/dechlorination of the oxime hydrochloride generated during said phonitrosation, preferably carried out in a glass microreactor.

Method for preparing lactames, comprising a photonitrosation step, followed by a Beckmann transposition step

In order to replace methyl bromide in all the uses thereof in soil or substrate treatment, the invention relates to the use of at least one sulphur compound having general formula: wherein R represents an alkenyl or alkyl radical, n is equal to 0, 1 or 2, x is a number between 0 and 4 and R' represents an alkenyl or alkyl radical or, only if n=x=0, a hydrogen or alkali-metal atom. The sulphur compounds (in particular dimethyldisulphide) can be applied according to standard soil treatment methods (by injection, spraying, dripping, sprinkling) and said compounds have no phototoxic effects.

Pesticide treatment of soils or substrates with sulphur compounds

The present invention is directed to the pesticidal treatment of stored foodstuffs, chambers, structures and works of art, using a volatile sulphur compound of general formula: in which R represents an alkyl or alkenyl radical containing from 1 to 4 carbon atoms, n is equal to 0, 1 or 2, x is a number ranging from 0 to 4, and R' represents an alkyl or alkenyl radical containing from 1 to 4 carbon atoms or, only if n=x=0, a hydrogen atom. These sulphur compounds (in particular dimethyl disulphide) are applied by nebulization directly to the material to be treated.

Pesticidal treatment of stored goods, enclosures, structures and works of art, with sulphur compounds
