    • The invention relates to a method for producing alkyl polyglycol carboxylic acids and polyglycol dicarboxylic acids by means of direct oxidation. The aim of the invention is a method for producing compounds of the formula (Ia) and/or compounds of the formula (Ib), wherein R1 is a saturated, linear or branched alkyl radical having 1 to 22 carbon atoms or a monounsaturated or polyunsaturated linear or branched alkylene radical having 2 to 22 carbon atoms; R2, R3 independently from each other represent hydrogen, a linear or branched alkyl radical having 1 to 22 carbon atoms, a monounsaturated or polyunsaturated linear or branched alkylene radical having 2 to 22 carbon atoms, or an aryl radical having 6 to 12 carbon atoms; X represents an alkyl radical having 2 to 4 carbon atoms; n represents a number between 0 and 100; m represents a number between 1 and 250; and B represents a cation or hydrogen, and/or the corresponding protonized carboxylic acids, in that one or more compounds of the formula (IIa) and/or the formula (IIb), with R1, R2, R3, X, n, and m having the meanings indicated above, are oxidized with oxygen or oxygen-containing gases in the presence of a gold-containing catalyst and at least one alkaline compound.
    • 本发明涉及通过直接氧化制备烷基聚乙二醇羧酸和聚乙二醇二羧酸的方法。 本发明的目的是制备式(Ia)化合物和/或式(Ib)化合物的方法,其中R 1是具有1至22个碳原子的饱和,直链或支链烷基或单不饱和或多不饱和的 具有2至22个碳原子的直链或支链亚烷基; R2,R3彼此独立地表示氢,具有1至22个碳原子的直链或支链烷基,具有2至22个碳原子的单不饱和或多不饱和直链或支链亚烷基或具有6至12个碳原子的芳基; X表示碳原子数2〜4的烷基, n表示0至100之间的数字; m表示1至250之间的数字; 并且B表示阳离子或氢,和/或相应的质子化羧酸,在一个或多个式(IIa)和/或式(IIb)的化合物中,R 1,R 2,R 3,X,n和 具有上述含义的m在含金催化剂和至少一种碱性化合物的存在下用氧或含氧气体氧化。
