Charge neutralization Chemical derivatization

Thus, native CDs and their derivatives are definitely established as a major group of chiral selectors in CE, CEKC, and MEKC. Perhaps, in the near future, the main emphasis will be directed to the use of a well-characterized, single isomer native and derivatized (neutral and charged) CDs as chiral selectors and to the use of chiral CE for solving problems in chemical, agrochemical, food, environmental, and, mainly, in... 

Since nonionic carbohydrate-derived surfactants are available in sufficient quantities and at competitive costs at present, anionic versirais of these chemicals such as carboxylates, sulfates, and phosphates are less common. Until now there have been only a few products (anionic derivatives of APG) established in the market [29]. Indeed, the derivatization of neutral sugar-based surfactants to furnish anionic compounds is not easy at a competitive cost with the sulfate (alcohol ether sulfates, AES) and sulfonate (linear alkylbenzene sulfcaiates, LAS) surfactants derived from petrochemicals. Within this context, uronate derivatives possessing carboxylate functionality represent attractive starting materials for the preparation of negatively charged surfactants.
