ABSTRACT:
Pectic acid and pectinic acid may be totally or partially esterified with aliphatic, arylaliphatic, cycloaliphatic or heterocyclic alcohols. When the acid is only partially esterified, the remaining free carboxyl groups may be salified with inorganic or organic bases. The esters may be used in the pharmaceutical, biomedical, alimentary and cosmetic fields. The esters may be prepared from a quaternary ammonium salt of pectic acid or pectinic acid and an esterifying agent such as a halogenide.
