Production of Cyclic Anhydride-Modified Starches

7/5/2021 · 2.3. Modification of Starch with Cyclic Anhydrides in a Melt Mixer Uncooked waxy starch (22.0 g, 0.136 mol GPy units) and distilled water (4.4 mL, 0.244 mmol, 20 wt% wrt starch) were loaded into a melt mixer (Half Size Mixer, C. W. Brabender, 30 mL capacity Fractionation effects of polystyrene on acylation reaction 5/4/2013 · With acylation with PHA (d), four characteristic signals around 7.2, 7.3, 7.6, and 7.8 ppm, due to aromatic protons, are observed. And also with acylation with PA (e), characteristic signals around 3.4 ppm, due to methylene (CH 2 ) protons of –COCH 2 CH 3 moiety and about 1.3 ppm due to methyl (CH 3 ) protons of –COCH 2 CH 3 moiety, are observed.

Acylation of Lignin with Different Acylating Agents by

12/8/2018 · All acylated lignins that are prepared by microwave-assisted acylation with non-cyclic anhydrides as acylating agents are more thermally stable than the original lignin, and longer chains of anhydride lead to lower glass transition temperatures (T g) of acylated16,].

of lignin-based polycarboxylates as a plasticizer for

For acetylation, 50 mg of each sample was dissolved in 0.5 mL of pyridine, and 0.5 mL of acetic anhydride was added. Acetylation was conducted for 2 h at 105 °C. Next, acetylated KL was obtained by adding the solution into water. Polymers | Free Full-Text | Acylation of Lignin with Differe 12/8/2018 · Acylated lignins with substituents consisting of different lengths of carbon chains were prepared by a mechanical activation-assisted solid phase synthesis (MASPS) technology with a customized stirring ball mill as a reactor. The structures and properties were analyzed by UV/Vis, FTIR, NMR, SEM, DSC, and TG. The results showed that the acylated lignins were successfully prepared with either

High-Solids, Solvent-Free Modification of Engineered

All runs were carried out above the melting point of the SA (122 C) at 130 C for 14 h. The pertinent acylation reaction does not involve a byproduct, and therefore no mass loss was anticipated. However, the mass loss curves quoted in Figure 4 indicate that the neat anhydride (blue line) was volatile at this temperature and the extrapolated loss at 14 h would be ca. 52 wt.%. of lignin-based polycarboxylates as a plasticizer for For acetylation, 50 mg of each sample was dissolved in 0.5 mL of pyridine, and 0.5 mL of acetic anhydride was added.
