    Abstract: Gasoline and diesel fuels contain minor amts. of: (a) an ethoxylated, propoxylated or butoxylated mono- or polyhydroxy cpd. with a no.-av. molecular wt. of 500-6000; and (b) an NTA or EDTA imide deriv. of formula (I): (where Q = CH2COX or CH2CH2N(CH2COX)2; X = NHR or X+X = NR; R = 7-18C aliphatic gps. (same or different)). Component (a) is specifically derived from an alcohol of formula R(OH)n, where n = 1-4 and R = 1-20C alkane, by reaction with butylene oxide or a combination of propylene oxide and butylene oxide in a ratio of 5:95 to 95:5. The (a):(b) wt. ratio is 5:1 to 1:3. The fuels contain 0.01-0.3 wt.% (a) + (b).

    Abstract: Preparation of the trisodium salt of isoserine-N,N-diacetic acid (I) by reaction of acrylonitrile with aqueous hydrogen peroxide to give glycidamide (II) and further reaction of II with the disodium salt of iminodiacetic acid (III) to give I, by carrying out the process continuously and, in it, successively a) reacting together acrylonitrile and aqueous hydrogen peroxide at pH 7-8 and 30-60 DEG C, b) removing unreacted acrylonitrile by distillation, c) passing the reaction mixture over a solid hydrogen peroxide-decomposing catalyst, d) reacting the aqueous solution of II, obtained in this way, with III at pH 7-9 and 40-90 DEG C, e) reacting the resulting solution with a basic sodium compound at pH 9-14 and 60-95 DEG C, f) removing the ammonia which is produced by distillation and g) if desired, working up the aqueous solution of I, obtained in this way, in a manner known per se to give solid I.
