In this process a stoichiometric amount of 35% w/w concentrated hydrochloric acid was added to the zwitterion, stirred for 30 min at room temperature to form the viscous ionic liquid and then kept in vacuum desiccator prior to use.
For clays modified with zwitterion, nonionic and anionic surfactants (TMG, HEC, TRITON X-100, LABSA and SLES), it was seen that the liquid limit and plasticity index increased when surfactant percentage was increased.
Zwitterions are chemical compounds that have a total net electrical charge of zero but contain positively and negatively charged groups.
Their model which employs the zwitterions mechanism for the C[O.sub.2]-amine reaction, constant global concentration of amine based species and equal diffusion coefficients was numerically solved.
The two species may then react to couple the radicals and produce a Zwitterion. The Zwitterion is stabilized via resonance through both the MA component and the ITX component.
This structure decomposes to Zwitterion (1) and a carbonyl compound (2), which can recombine to a normal ozonide (3).
