    • Process for producing hydroxyalkylaminoacetic acids having the general formula (I):R--CHOH--CHR.sub.1 --NR.sub.2 --CH.sub.2 --COOH (I)in which:R represents a hydrogen atom, a C.sub.1 -C.sub.18 -alkyl group, with straight or ramified chain, or a phenyl group possibly substituted by one or more radicals (preferably one or two) selected from the group comprising: C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alcoxy or halogeno radicals;R.sub.1 represents a hydrogen atom or a C.sub.1 -C.sub.4 -alkyl group;R.sub.2 represents a C.sub.1 -C.sub.18 -alkyl group or R.sub.3 --CHOH--CHR.sub.4 --group in which R.sub.3 identical to R represents a hydrogen atom or a C.sub.1 -C.sub.18 -alkyl group with straight or ramified chain, and R.sub.4 is identical to R.sub.1, according to which glyoxal is reacted hot upon a secondary hydroxylated amine having the general formula (III): ##STR1## in which R, R.sub.1 and R.sub.2 have the meaning as given above.
    • 制备具有通式(I)的羟基烷基氨基乙酸的方法:R-CHOH-CHR1-NR2-CH2-COOH(Ⅰ)其中:R表示氢原子,直链或支链的C1-C18-烷基, 或可以被一个或多个选自以下的基团(优选一个或两个)取代的苯基:C 1 -C 4 - 烷基,C 1 -C 4 - 烷氧基或卤代基; R1表示氢原子或C1-C4烷基; R2表示C1-C18-烷基或R3-CHOH-CHR4-基,其中与R相同的R3表示氢原子或具有直链或支链的C1-C18-烷基,R4与R1相同,根据 (III)的仲羟基化胺:其中R 1,R 2和R 2具有如上所述的含义。
