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: Ethyl N-(o-, m-, p-)sulphophenyl-thiocarbamates (IA) are new. Also claimed is the use of thiocarbamate esters of formula (I) as depressant for CuS in the sepn. of Mo and Cu minerals by froth flotation: R -O-C(=S)-NH-R (I); R = 1-6 C aliphatic hydrocarbyl gp., opt. with hydrophilic substit(s).; R = 1-6 C aliphatic hydrocarbyl or phenyl gp. with hydrophilic substit(s).

Abstract: Alkenylsuccinamic acid derivatives of the formulae are used in water- and/or oil-containing formulations or liquids for treating metals as anticorrosive agents and emulsifiers. In the formulae A = C6-C30-alkenyl, R = H or R , R = -R -O-(CH2CHR -O)nH, R = C1-C10-alkylene, R = -H or -CH3, n = 0 to 50 and Me is an alkali metal ion, a proton or an ammonium ion of the formula HN R R R , where R , R and R are identical or different and denote hydrogen, C1-C6-alkyl and hydroxyalkyl.
