Abstract: PROBLEM TO BE SOLVED: To obtain the subject high-purity compound in high yield without causing waste water, by reacting N-lauroyl-L-glutamic acid dimethyl ester with n-butylamine in the presence of a specific auxiliary solvent. SOLUTION: N-Lauroyl-L-glutamic acid dimethyl ester (hereinafter abbreviated as the ester) is reacted with n-butylamine in the presence of a hydrocarbon or a hydrocarbon mixture as an auxiliary solvent. n-Nonane, n-decane and a high-boiling multi-alkylated cyclohexane derivative having >=100 deg.C boiling point are preferable as the hydrocarbon. The ratio of the auxiliary solvent to the ester used is preferably 50-150wt.%. The amount of the n-butylamine used is preferably 3-6mol based on 1mol of the ester. Preferably, after the reaction, excessive n-butylamine is removed by distillation and a polar solvent such as acetone is added to the reaction mixture to precipitate the objective compound.

Abstract: The novel urethanes correspond to the formula I below in which a denotes a number from 5 to 17 and b denotes a number from 1 to 7. These urethanes are prepared by reacting the corresponding perfluoroalkylethanol/epichlorohydrin adducts with toluelene diisocyanates. The novel aqueous dispersions are essentially composed of the novel urethanes, cationic or betaine emulsifiers and non-ionic emulsifiers, water-insoluble carboxylic and/or dicarboxylic acid esters and alkanediols or polyalkanediols which can be etherified on one or both sides, in water. The novel urethanes and the novel aqueous dispersions are used to impart an oleophobic and hydrophobic finish to textiles, leather and furs. They are also suitable for the treatment of unpainted timber, for example unpainted furniture.

Abstract: The novel urethanes conform to the following formula I: where a is from 5 to 17 and b from 1 to 7. These urethanes are prepared by reacting the corresponding perfluoroalkylethanol-epichlorohydrin adducts with toluylene diisocyanates. The novel aqueous dispersions consist essentially of novel urethanes, cationic or betainic and nonionic emulsifiers, water-insoluble carboxylic and/or dicarboxylic esters and alkanediols or polyalkanediols, which may be etherified in either or both positions, in water. The novel urethanes and the novel aqueous dispersions are used for conferring oleophobic and hydrophobic properties on leather and furs.
