A green approach to starch modification by solvent-free method with betaine hydrochloride

International Journal of Biological Macromolecules, 2021
In this study, a novel simple and eco-efficient, semi-dry method with a spray system for starch modification has been developed. Compared to conventional semi-dry methods, this method does not use solvents so that no slurry or semi-liquid mixture is obtained, the material is in a moisted/semi-moisted state.

Molecular association of betaine and betaine hydrochloride in aqueous solutions – a study by Raman spectroscopy

Biochimica et Biophysica Acta (BBA) - General Subjects, 2001
Raman vibrational spectroscopy, at 298 K, has been used to study the hydration of betaine hydrochloride and betaine in the concentration range 0.5-2 M. The observed changes in the internal vibrations of the solutes, namely, in the C=O, COO- and C-H stretchings, and in the components of the O-H stretching band are consonant with anionic water-betaine ...

Calculation of the vibrational spectra of betaine hydrochloride

Journal of Molecular Structure, 1997
Abstract The molecular geometries of betaine hydrochloride, BET·HCl, and free protonated betaine, BET·H + , were calculated with the 6–31G(d,p) basis set at the SCF, MP2 and DFT levels of theory. At the SCF level, the minimum energy corresponds to the ionic pair, B + Htctdot;A − , however, the equilibrium Otctdot;Cl distance is 0.14 A shorter than ...

Spectroscopic and theoretical studies of bis(dimethylphenyl betaine) hydrochloride monohydrate

Vibrational Spectroscopy, 2015
Abstract Bis(dimethylphenyl betaine) hydrochloride monohydrate was prepared and characterized by FTIR, Raman spectroscopes, and B3LYP/6-311++G(d,p) calculations. In the optimized structure of the complex, two betaine moieties are joined by a very strong asymmetric hydrogen bond with an O⋯O distance of 2.439 A.
