Description
-Patented Sept. 20, 1938 UNITED STATES PATENT OFFICE POLYAMINO CARBOXYLIC ACIDS AND PROCESS OF MAKING SAME Ferdinand Mi'mz, Fran kIort-on-the-Main, Germany, assignor to General Aniline Works, Inc., New York, N. Y., a corporation of Delaware No Drawing. original application October 22,
1936, Serial No. 107,020.
Divided and this application April 3, 1937, Serial No, 134,737. In Germany October 30, 1935 2 Claims. (cl. 260-534) This application is a division o f my copending application Ser. No. 107,020, filed October 22, 1936, which relates to the use ofamino polycarboxylic acids for avoiding and rendering 5 harmless the precipitates of water-insoluble metal salts, particularly formed owing to the hardness 1 In this manner polyamino-polycarboxylic acidsare obtained which correspond to the general formula:
noocnlc cmccon ,HOOCHC CHICOOE wherein R stands for a lower alkylene radicle.
The following example will :iurther illustrate how the said invention may be carried out in 26 practice, but the invention is not restricted to this example. The parts are by weight.
Example parts of ethylene diamine in an aqueous solution of 10% strength are mixed with 466 parts of the sodium salt of monochloracetic acid and 212 parts of sodium carbonate and the mixture is heated at to C. for 8 to 10 hours. Then v470 parts oi a hydrochloric acid of 20 B. are added. When cool an acid of the formula:
11000-1110 CHIGOOH N-CH -Clzh-N' HUGO-Hi0 011.0001: 10
precipitates, which is scarcely soluble in water and may be recrystallized from water.
I claim: d i 1. Polyamino polycarboxylicacids correspond:
ing to the formula: ll
noocmc cmcoon N v noocmc cmcoon wherein It stands for a lower alkylene' radicle.
2. A polycarboxylic acid of the formula;
aooc-mc omccon n-cm-cmnoes-mo which is scarcely soluble in water and may be recrystallized rrom water.
