“…Silicic acid esters are iiisoluble in water and in organic solvents (147,148). Pectic acid amide (-CONHz) is completely water insoluble, probably due to intermolecular hydrogen bonds between amide and hydroxyl groups (351). Alkyl amides (---CONHR), however, are soluble in water, the alkyl groups acting as internal plasticizers (52).…”

“…Side groups reduce the coagulability. Partial amides of pectic acid are very sensitive toward electrolytes (353,351 ). Partial amino-ethylene amides of pectic acid, being polyampholytes, are flocculated a t the isoelectric point (81,365).…”
