New type Polybasic acids containing either ether linkages or ether and hydroxyl groups were prepared from glycerol, diglycerol, triglycerol and tetraglycerol. The polybasic acids were synthesized by the reaction of the corresponding alcohols with ethyl diazoacetates, monochloroacetic acid or acrylonitrile. And their building performances detergency were compared with those of disodium oxadiacetate (ODA) -Na and sodium tripolyphosphate (STPP) in a sysem formulating alkylbenzene sulfonate (LAS). The detergency were tested on naturally soiled cotton patches and the detergency powers were evaluated by Scheffe's method. <BR>From the results summarized in Fig.-1, it is evident that a building performance of the tetrasodium salt of diethyl 5, 9-bis (ethoxycarbonylmethoxy) -3, 7, 11-trioxatridecanedioate (VIII) n=2 was similar to that of STPP, and a building performance of pentasodium salt of diethyl 5, 9, 13-tris (ethoxycarbonylmethoxy) -3, 7, 11, 15-tetraoxaheptadecanedioate (VIII) n=3 and trisodium salt of tris (ethoxycarbonylmethyl) glycerol (VIII) n=1 was slightly superior to that of disodium salt of oxadiacetic acid (ODA). But the corresponding polypropionates did not show the good building power. In comparison with the large biodegradability of disodium oxadiacetate (96.44%), the biodegradabilities of these sequestrant builders were rather poor : (VIII) n=2-Na ; 6.6O%, (VIII) n=1-Na ; 8.35%
