摘要:
The invention relates to a storage-stable condensation product prepared from 1-amino-2-propanol and formaldehyde in a molar ratio in the range from 1: 2.0 to 1: 3.1. The condensation product contains less than 10% by weight of water. The invention additionally relates to the preparation of the condensation product and the use thereof for reducing the amount of hydrogen sulphide in liquids and gases.
摘要:
The invention relates to an additive mixture for fuels, which comprises a) at least one N-formal, b) at least one antioxidant and c) at least one corrosion inhibitor. The additive mixture ensures that the additized fuels and lubricants have biocidal and corrosion-inhibiting additization, especially when they comprise proportions of renewable raw materials, such as biodiesel, and when they are in contact with copper-containing surfaces.
摘要:
The invention relates to a preparation which comprises a) at least one N-formal and b) at least one dialkylhydroxylamine. The preparation is preferably formulated as a concentrate. The invention further relates to the use of the preparation (in particular in the form of the concentrate) for the reduction of free oxygen and the preservation of water, and also correspondingly additivated water. The mixture of N-formals with dialkylhydroxylamine is not only outstandingly compatible, but considerably improves the activity of dialkylhydroxylamines as oxygen scavengers.
摘要:
The invention relates to a microbicidal use solution which comprises a) one or more isothiazolin-3-ones and b) one or two organic amines selected from N-dodecylpropane-1,3-diamine and bis(aminopropyl)-dodecylamine and optionally c) one or more oxidizing agents. The use solution is preferably in the form of technical and domestic products.
摘要:
The invention relates to a preparation comprising a) 10 to 80% by weight of α,α′,α″-trimethyl-1,3,5-triazine-1,3,5-(2H,4H,6H) triethanol (TTT) and b) one or more additives selected from i) ammonia, ii) alkanolamines with primary amino group and alkyl group having at most eight carbon atoms and iii) alkylamines with primary amino group and alkyl group having at most eight carbon atoms, where the weight ratio a):b) is in the range from 100:30 to 100:1. The preparation is present as semi-concentrate and has an advantageously lower viscosity, is moreover storage-stable, in particular storage-stable over a long period.
摘要:
The invention relates to a microbicidal composition in the form of a concentrate which comprises a) one or more isothiazolin-3-ones, b) one or more organic amines with an alkyl group having at least 8 carbon atoms and c) one or more oxidizing agents. The concentrate is storage-stable and is used for the preservation of technical and domestic products.
摘要:
The invention relates to the use of a composition comprising a) 3,3'- methylenebis(5-methyl oxazolidine) and b) one or more additives selected from among (i) urea, urea derivatives, amino acids, guanidine and guanidine derivatives and (ii) 1,2-diols in the removal of sulphur compounds from process streams. The composition is preferably used in the removal of hydrogen sulphide from process streams.
摘要:
Composition characterized in that, it consists of, for 100 weight %: a) From 1 weight % to 10 weight % of at least one of 1,2-benzisothiazolin-3one and its derivatives, b) From 0.5 weight % to 5 weight % of at least one of 2-mercaptopyridine N-oxide, its salts and its derivatives c) From 1 weight % to 6 weight % of N,N-bis(3-amino propyl)-dodecylamine d) At least one alkalinizing agent, in a concentration such that the pH is greater than 11, and e) Water up to 100 weight %; the process for its preparation and its as an additive of technical products.
