Abstract: The present invention relates to N-alkyl-N'-poly(oxyalkyl)hexahydropyrimidines of the formula I in which R is C1-C30-alkyl or C2-C30-alkenyl, R is hydrogen or C1-C3-alkyl, A denotes 1,2-alkylene groups having 2 to 10, preferably 2 to 5, C-atoms, and p represents a number from 1 to 50. The invention furthermore relates to the use of N-alkyl-N'-poly(oxyalyl)hexahydropyrimidines of the formula I as corrosion inhibitors in water/oil emulsions as they are found in mineral oil.

Abstract: According to the invention the alkoxylation of compounds containing active hydrogen atoms is carried out in the presence of specific alkaline earth metal salts of alkylor alkenylsuccinic monoesters as catalyst. The alkoxylates obtained have a narrow homolog distribution and a good appearance.

Abstract: According to the invention, the alkoxylation of compounds containing active H atoms is carried out in the presence of specific alkaline earth metal salts of alkyl- or alkenylsuccinic acid monoesters as catalyst. Alkoxylates having a narrow homologue distribution and good appearance are obtained.

Abstract: HOE 90/F 182 Salts of alkenylsuccinic monoamides and their use as anticorrosive agents and emulsifiers for metal-working oils The invention relates to alkenylsuccinic monoamides of the formulae or in which R is C13-C30-alkenyl and Me+ is an alkali metal ion, a proton or an ammonium ion of the formula +NHR1R2R3 and R1, R2 and R3 are identical or different and are hydrogen, 2-hydroxyethyl or 2-hydroxypropyl. The invention further relates to the use of these alkenylsuccinic monoamides as anticorrosive agents in waterand/or mineral oil-containing formulations, if appropriate together with ethoxylates and/or fatty acid alkanolamides, and water- and/or mineral oil-containing anticorrosive agents, containing alkenylsuccinic monoamides of this type.

Abstract: The present invention relates to a process for separating molybdenum minerals and copper minerals by flotation using a depressant for copper sulfide, which comprises using one or more thiocarbamic esters of the formula I (I) in which R1 is an aliphatic hydrocarbon radical which is unsub stituted or substituted by hydrophilic groups and has 1 to 6 carbon atoms and R2 is an aliphatic hydrocarbon radical which is substi tuted by hydrophilic groups and has 1 to 6 carbon atoms or is a phenyl radical which is substituted by hydrophilic groups, as depressants.
