Calcium sequestering agents based on carbohydrates

Chemical Modification of Inulin, a Valuable Renewable Resource, and Its Industrial Applications

“…The calcium carbonate binding capacity was found to be excellent (2.0-2.5 mmol of Ca/g), comparable to that of commercial builders and better than the products prepared from starch. 90 The sequestering activity of the oxidized inulin shows indeed a linear relationship with the degree of oxidation of inulin.…”

Two-steps synthesis of D-glucaric acid via D-gluconic acid by electrocatalytic oxidation of D-glucose on gold electrode: Influence of operational parameters

“…One of these products is glucaric acid, whose immense market value (at USD 550.4 million in 2016 [9]) is due to its high functionalization, which makes it a potential building block for the production of a variety of commodity products: i.e. detergents [10], polymers [11][12][13][14][15], new nylons (sustainable precursor for adipic acid production [13]), hyperbranched polyesters and food [16], cement and concrete additives [17]. In particular, the interest in the use of glucaric acid for the manufacture of detergents originates from recent economic policies adopted in the EU and US against the use of phosphates, as they are responsible for a decrease in water quality [18][19][20][21].…”

Determination of the Substituent Distribution of O-(2-Hydroxypropyl)Inulin by Methylation Analysis

“…2,1-fructan inulin should also be influenced by the adjacent anomeric center in this way. Timmermans et al reported on slight differences of reactivity in the order 3 > 4 > 6 for the methylation of the 2,1-linked fructosyl moiety in the inulinrelated tetrasaccharide nystose [11], while Besemer et al found a preferred carboxymethylation of inulin in position 4 [12]. This difference may be explained by the much higher concentration of base in Williamson-type ether formations compared to the addition of an oxirane, where only catalytic amounts of base are used.…”
