抄録

This report relates to the detergency building action of organic acids containing ether linkages. The authors synthesized two series of oxamonobasic acids, i.e. alkyloxyacetic acids and 3-alkyloxypropionic acids, two kinds of oxatribasic acids, i.e. 2-oxapentane-1, 5, 5-tricarboxylic acid and 3-oxahexane-1, 6, 6-tricarboxylic acid, and alkylated oxadibasic acids, i.e. 1, 2-dicarboxymethoxyalkane. The building performances of the sodium salts of these acids compared with those of disodium oxadiacetate and sodium tripolyphosphate (STPP) using alkylbenzenesulfonate (LAS).<BR>The detergency tests were carried out on naturally soiled cotton fabrics and the detergency powers were evaluated by Scheffe's method.<BR>From Table-13 and Table-14, it is evident that in low molecular organic electrolytes, the destinction among oxamono-, oxadi- and oxatribasic acids is not clear, but the acid which has the minor molecular weight per carboxyl radical tends to exhibit better detergency building performance. On the other hand, much better detergency performance can be expected by the introduction of long chain group to oxamonobasic acid such as dodecyloxyacetic and 3-dodecyloxypropionic acids. This might be due to the synergism with LAS and dodecyloxyacetic and dodecyloxypropionic acids in their detergency.
