Abstract: Alkyl- and/or alkenyl-succinamic derivs., referred to as salts, of formula (Ia) and/or (Ib) are new: R1 = 6-100C alkyl or alkenyl; R2 = a deoxy-saccharide gp. derived from a mono-, di- or oligosaccharide; R3 = H, 1-6C alkyl or R2; X = H, alkali(ne earth) metal, NHR4R5R6 or NHR2R3R4; R4-R6 = H, 1-20C alkyl, OH, 1-6C hydroxyalkyl or 3-6C polyhydroxyalkyl. Also claimed is the prodn. of alkyl- and/or alkenyl-succinamate salts by reacting alkyl- or alkenyl-succinic anhydrides with amino-substd. carbohydrates in the presence of basic cpds.

Abstract: Process for preparing water-soluble polysaccharides contg. (a) substituents chosen from alkyl, hydroxyalkyl, carboxyalkyl and sulphoalkyl and (b) N,N-disubstd. aminoalkyl gps., comprises alkylating a polysaccharide in the presence of a base with a mixt. of one or more alkylating agents (I) chosen from alkyl gp.-transferring cpds. (Ia), hydroxyalkyl gp.-transferring cpds. (Ib), carboxyalkyl gp.-transferring cpds. (Ic) and sulphoalkyl gp.-transferring cpds. (Id), and an N,N-disubstituted aminoalkyl sulphuric acid ester (II).
