    Abstract: Alkanolamine salts of amido acids of the formula I in which the ring denotes a mononuclear aromatic ring or a mono- or bicyclic aliphatic ring system in each case having 5 or 6 C atoms per ring, R denotes an isoalkyl radical having a chain of 6 to 8 C atoms at the longest and a total carbon number of 8 to 12 C atoms and R denotes a radical - alkylene - X, it being possible for the alkylene chain to be straight-chain or branched and to contain 1 to 4 carbon atoms, where X represents OR , O(C2H4O)n-R , O(C3H6O)n-R , NR R , CN, CONH2 or COOR and R denotes hydrogen, C1- to C4-alkyl and n = 1 to 4, the carboxyl and carboxamide group in formula I being bonded to non-olefinic C atoms and being arranged in neighbouring positions, and the use of these salts as corrosion inhibitors in aqueous systems.

    Abstract: A process for the preparation of 1,3-disubstituted 4,5-cis-dicarboxy-2-imidazolidones useful as intermediates in the preparation of Vitamin H (biotin), said intermediates have the general formula in which R is an aliphatic hydrocarbon radical having 1 to 8 carbon atoms, an aralkyl radical or an aromatic hydrocarbon radical, preferably an allyl radical or a benzyl radical, comprising reacting a defined diaminosuccinic acid with phosgene in the presence of an alkali metal hydroxide.

    Abstract: Quaternary ammonium compounds of the formula where R1 and R2 are identical or different and each is H, halogen, phenyl, alkyl, alkoxy or alkylthio, R3 is H or alkyl, hydroxyalkyl, cycloalkyl or aralkyl, R4 and R5 are identical or different and each is alkyl, phenyl, cycloalkyl or aralkyl or R4 and R5 together are a -(CH2)4- bridge, a -(CH2)5- bridge or a -(CH2)2-O-(CH2)2- bridge, R6 is alkyl and X(-) is Cl(-), Br(-), I(-), CH3SO4(-) or C2H5SO4(-), a process for their preparation from Mannich bases of the formula and alkylating agents, and the use of these quaternary ammonium compounds as initiators for the photopolymerization of polymerizable mixtures containing olefinically unsaturated compounds, especially for the preparation of aqueous polymer dispersions or polymer solutions.
