摘要:
Peptides having essentially the sequence of bovine pancreatic trypsin inhibitor (aprotinin) wherein one or more of the amino acids at positions 15, 16, 17, 18, 34, 39 and 52 are replaced by any naturally occurring amino acid produced by recombinant DNA technology, process, expression vector and recominant host therefor and pharmaceutical use thereof. Such peptides being useful as therapeutic agents in diseases connected with the presence of excessive amounts of proteinases.
摘要:
The invention relates to the use of manganese oxalates in detergents and cleaning agents, in particular in cleaning agents containing peroxy compounds for hard surfaces.
摘要:
The invention relates to a method for producing acyloxy benzoic acids of the formula (I), in which R1 is a linear or branched saturated alkyl group with 6 to 30 carbon atoms, a linear or branched mono- or polyunsaturated alkenyl group with 6 to 30 carbon atoms, or an aryl group with 6 to 30 carbon atoms. The acyloxy benzoic acids of the formula (I) are produced from para-hydroxy benzoic acid and a corresponding carboxylic acid halide in the presence of an alkali hydroxide.
摘要:
The invention relates to co-granules containing a) at least one bleach activator, b) at least one metal-containing bleach catalyst, and c) at least 5 wt. % of at least one organic acid. The co-granules are easy to produce, have a high stability in storage and are advantageously suitable for producing cleaning products and detergents and especially products for cleaning crockery in a machine.
