Abstract: Alkyl glucoside amino carboxylates of the formula in which at least two R substituents are or H, L is an iminodiacetate, aspartate, glutamate, sarcosinate, glycinate, serinate, hydroxyaspartate, ethanolaminoacetate, diethanolamino, alanate or taurinate residue, X is hydrogen, alkali metal, ammonium or substituted ammonium ion, R is R is H or -CH3 and n is 0 to 4, preparation of the compounds of the formula I by esterification of (a) hydroxyalkyl glucosides with (b) maleic anhydride in the molar ratio (a):(b) of 1:at least 2 to 5.5 and addition of amines or amino acids of the formula L-H, in which L has the abovementioned meaning, onto the double bonds of the esters. The compounds of the formula I are used as complexing agents for heavy metal ions.

Abstract: N,N,N',N'-Tetracyanomethyl-1,3-diaminopropane is prepared by a reaction of 1,3-diaminopropane and formaldehyde and a compound giving cyanide ions in an aqueous medium, a) by reacting 1,3-diaminopropane, formaldehyde and the compound giving cyanide ions first in the weakly acidic range and at a temperature of 20-60@C to give N,N'-dicyanomethyl-1,3-diaminopropane and b) completing the cyanomethylation to give the tetracyanomethyl compound in the strongly acidic range at a temperature of 40-80@C.

Abstract: The process entails the extraction of long-chain alkyl glucosides from reaction mixtures which can be obtained by reacting monosaccharides and alcohols containing at least 8 C atoms or by transacetalisation of short-chain alkyl glucosides with alcohols having at least 8 C atoms, and which in each case are adjusted to a pH above 6, with the aid of water.
