Abstract:
The present invention relates to a method for producing C4-C15 lactams, in which a C1-C10 alkyl nitrite is reacted with a C4-C15 cycloalkane and is exposed during the reaction by means of a light-emitting diode. The thus produced C4-C15 cyclohexanone oxime is then further reacted to a C4-C15 lactam, and the formed C1-C10 alcohol is recycled in the production of the C1-C-10 alkyl nitrite.
Abstract:
The present invention is in the field of processes for the generation of thin inorganic films on substrates. More specifically, the present invention relates to a process comprising bringing a compound of general formula (I) into the gaseous or aerosol state and depositing the compound of general formula (I) from the gaseous or aerosol state onto a solid substrate, wherein R11, R12, R13, R14, R15, R16, R17, R18 are independent of each other hydrogen, an alkyl group, an aryl group, or a trialkylsilyl group, R21, R22, R23, R24 are independent of each other an alkyl group, an aryl group, or a trialkylsilyl group, n is 1 or 2, M is a metal or semimetal, X is a ligand which coordinates M, and m is an integer from 0 to 3.
Abstract:
Method for producing alkoxylated polyalkylene polyamines, comprising the following steps (a) homogenously-catalysed alcohol-amination, wherein aliphatic amino alcohols are reacted with one another or aliphatic diamines or polyamines with aliphatic diols or polyols with elimination of water in the presence of a homogenous catalyst, to form polyalkylene polyamines, (b) reaction of said polyalkylene polyamines with alkylene oxides into alkoxylated polyalkylene polyamines. Special alkoxylated polyalkylene polyamines, obtainable by means of such methods and alkoxylated polyalkylene polyamines and method for the production thereof. Use of alkoxylated polyalkylene polyamines as detergent additives, dispersing agents, textile auxiliary agents, wood protection agents, and corrosion protection agents.
Abstract:
The invention relates to a method for the production of polyalkylene polyamines by homogeneously catalyzed alcohol amination, wherein aliphatic alkanolamines are reacted with each other or aliphatic diamines or polyamines are reacted with aliphatic diols or polyols in the presence of a homogeneous catalyst while eliminating water and in the presence of hydrogen gas. The invention further relates to polyalkylene polyamines, which can be obtained by said methods, and to polyalkylene polyamines which contain hydroxyl groups, secondary amines or tertiary amines. The invention finally relates to uses of said polyalkylene polyamines as adhesion promoters in inks, adhesion promoters in composite films, cohesion promoters in adhesives, cross-linkers/hardeners for resins, primers for paints, wet adhesion promoters for dispersion paints, complexing agents and flocculants, penetration auxiliaries for use in wood preservation, corrosion inhibitors, and immobilization agents of proteins and enzymes.
