摘要:
The invention relates to the use of one or more N-substituted 2-pyrrolidone-4-carbonic acid esters of formula (1), where R1 and R2 independently represent linear, branched, or cyclic C1-C6 alkyl, as (a) solvent(s). Said compounds can be used as solvents in industrial applications, e.g. for the production of varnishes and paints, in chemical syntheses, for cleaning or degreasing, in petrochemical processes, in the electronics and photovoltaic industries, or in pesticide preparations, for example.
摘要:
The invention relates to pesticide preparations that contain one or more pesticides and one or more N-substituted 2-pyrrolidone-4-carboxylic acid derivatives and to the use of said pesticide preparations for controlling and/or combating weeds, fungal diseases, or insect infestation. The N-substituted 2-pyrrolidone-4-carboxylic acid derivatives act as adjuvants, emulsifiers, dispersants, and/or wetting agents in the pesticide preparations.
摘要:
The invention relates to a continuous method for producing hydroxycarboxylic acid amides, according to which at least one hydroxycarboxylic acid of formula (I) HO—R3—COOH (I) wherein R3 is an optionally substituted aliphatic hydrocarbon group comprising between 1 and 100 carbon atoms, is reacted with at least one amine of formula (II) HNR1R2 (II) wherein R1 and R2 are independently hydrogen or a carbon group comprising between 1 and 100 C atoms, to form an ammonium salt, and said ammonium salt is then reacted to form a hydroxycarboxylic acid amide, under microwave irradiation in a reaction pipe, the longitudinal axis of the pipe being oriented in the direction of propagation of the microwaves of a monomode microwave applicator.

The invention relates to compositions that contain A) one or more copolymers, said copolymers containing one or more structural units obtained from a) 19.9 to 75.9 wt. % glycerin, b) 0.1 to 30 wt. % at least one dicarboxylic acid, and c) 24 to 80 wt. % at least one monocarboxylic acid according to formula (I) R1—COOH (I), in which R1 is (C5-C29)-alkyl; (C7-C29)-alkenyl; phenyl; or naphthyl, and B) one or more solvents that are not miscible with water. The invention is characterized in that said compounds either do not contain water or contain water in a quantity less than or equal to 1.0 wt. % with respect to the total weight of the respective composition. The compositions are advantageously suitable for producing pesticide compositions for example.

The invention relates to the use of polysilazanes as permanent coatings on metal surfaces for the prevention of the susceptibility to fingerprints, characterized in that the polysilazane is in the form of a solution of a polysilazane or a mixture of polysilazanes of the general formula 1 —(SiR′R″—NR′″)n— (1) where R′, R″, R′″ independently=H, optionally-substituted alkyl-, aryl, vinyl- or (trialkoxysilyl)alkyl, n=a whole number such that the polysilazane has a number-average molecular weight of from 150 to 150,000 g/mol in a solvent. The invention further relates to a method for production of the coating.
摘要:
The invention relates to a surface coating comprising at least one type of perhydropolysilazane of the formula I wherein n is an integer of a value such that the perhydropolysilazane number-average molecular weight of from 150 to 150 000 g/mol, a solvent and a catalyst and, possibly one or more cobinding agents. The hardened coating has thickness of at least 1 micrometer, preferably ranging from 2 to 20 micrometers. The inventive coating containing at least one type of perhydropolysilazane is suitable for protecting rims, in particular, aluminum rims.
摘要:
Diketopyrrolopyrroles of the formula (I): wherein R1, R2, R3 and R4 independently of one another are a C1–C4 alkyl radical or a substituted or unsubstituted phenyl radical, wherein the phenyl radical can be substituted by 1, 2, 3 or 4 substituents from the group C1–C4 alkyl, C1–C4 alkoxy, CN, F, Cl, Br, NO2, CF3, S—C1–C4 alkyl, phenyl or (C1–C2)alkylenephenyl, with the proviso that at least one of the radicals, R1, R2, R3, or R4, is one of the stated substituted or unsubstituted phenyl radicals.
摘要:
The invention relates to suspension concentrates comprising a) one or more pesticides that are solid at room temperature, b) one or more specific copolymers, c) one or more additional auxiliary substances as applicable and d) one or more solvents. The copolymers b) comprise structural units of formula (I), wherein A stands for C2-C4-alkyls, B stands for a C2-C4-alkyl different from A, R stands for hydrogen or methyl, m is a number from 1 to 500, n is a number from 1 to 500, the sum of m+n is equal to 2 to 1000 and P stands for H or for a specific other concluding group, and structural units derived from specific ethylenic, unsaturated monomers that comprise an aromatic group, and structural units derived from specific ethylenic, unsaturated monomers that comprise aliphatic hydrocarbon residue. The suspension concentrates according to the invention are advantageously suitable for use as pesticides.
摘要:
The invention relates to the use of polysilazanes as a permanent coating on metal and polymer surfaces for preventing corrosion, increasing scratch resistance and to facilitate easier cleaning. The invention comprises a solution of a polysilazane or a blend of polysilazanes of the general formula 1 —(SiR′R″—NR′″)n— (1) where R′, R″ and R′″ are identical or different and independently of one another represent hydrogen or an optionally substituted alkyl, aryl, vinyl or (trialkoxysilyl)alkyl group and n represents a whole number and is calculated in such a way that the polysilazane has a numerical average molecular weight of 150 to 150 000 g/mol, in a solvent. The invention also relates to a method for producing the coating.
