    摘要: An improved method of preparing 1,6-di(N.sup.3 -cyano-N.sup.1 -guanidino) hexane from alkali dicyanamide and a hexamethylene diammonium salt in alcoholic solution or suspension. The reaction is carried out in the presence of a limited amount of water and of a catalytic amount of a base, preferably a tertiary amine. The pH of the reaction mixture at the start of the reaction is 8 to 10. After the reaction is over, the reaction mixture is compounded with water at a temperature above 80.degree. C. and the coarse product which crystallizes out is separated from the liquid phase.Preferably, sodium dicyanamide and hexamethylene diamine dihydrochloride, preferably formed in situ from aqueous 1,6-diaminohexane and aqueous hydrochloric acid, are reacted at pH 9-9.5 in n-butanol in the presence of 0.1 to 20% by wt. water in relation to the solvent including water.1,6-di(N.sup.3 -cyano-N.sup.1 -guanidino) hexane is obtained in a high yield (85-86%) and with great purity (95-97%) and with a considerably improved space-time yield.

    摘要: L-amino acids present in cleavage solutions obtained in the acylase-catalyzed cleavage of N-acetyl-D,L-amino acids are isolated by use of a strongly acidic ion exchanger in H+ form. First, the mother liquor from a previous treatment cycle is fed to the ion exchanger, and then the cleavage solution and finally the wash water and the discharge from the ion exchanger which is pH-controlled is analyzed into an "effluent water fraction", an "N-acetyl-D-amino acid fraction" and an "L-amino acid fraction". The last fraction is adjusted by addition of fresh cleavage solution to a pH of between 4.0 and 6.0, and from the mixture which is thus obtained the L-amino acid is isolated by crystallization. The mother liquor which is obtained is recycled back into a subsequent treatment cycle.
