    摘要: A new process for the production of high purity (cyclo)aliphatic diurethanes from (cyclo)aliphatic diamines, alcohols and urea in a multistep reaction in which (1) urea is reacted with alcohol with elimination of ammonia, (2) diamine is then introduced into the reaction mixture, optionally in the form of a solution in alcohol, and reacted with continuous release of ammonia and (3) the reaction mixture is freed from volatile components by distillation. The diurethanes produced by this process are useful as starting materials for the production of the corresponding diisocyanates by thermal urethane cleavage.

    摘要: A process is described for the preparation of cellulose derivatives containing amino groups that involves reacting, in the presents of water as a reaction medium, alkali cellulose or alkali cellulose derivatives with reagents represented by the following formula, X—(CH2)n—NR1R2 in which: X is selected from the group consisting of chlorine, bromine, iodine and a sulfonic acid radical R′SO3, in which R′ is an aromatic radical or an aliphatic radical; n is at least 2; and R1 and R2 independently of each other are selected from the group consisting of aliphatic substituents, branched alkyl substituents, cyclic alkyl substituents, aryl substituents, aryl substituents substituted by heteroatoms, H, and R1 and R2 together form a ring with the nitrogen. In the process, the mole ratio of cellulose to water, of said reaction medium, is 1:5 to 1:40 mol water per mol of anhydroglucose unit (AGU). Amino functional cellulose derivatives prepared in accordance with the method of the present invention are useful in cosmetic formulations and aqueous paper treatment compositions.
