Abstract
Abstract —Solubility of potassium and sodium orthophosphates in ethylene glycol was determined. DOI: 10.1134/S1070427212050278 Phosphates of metals are used in various industries (textile, cement, glass, and ceramic) and in everyday life, including the use as components of cleaning agents, min-eral fertilizers, structural materials, and food and fodder additives. In the most widespread handbooks and separate papers [1–5] there is only information about dibasic so-dium phosphate solubility in methanol and ethanol. Data on the solubility of acid and neutral orthophosphates of alkali metals in other alcohols, glycols, cellosolves, and glycerin are absent. It is known [6–13] that the alcoholysis of weak-acid salts (carbonates, orthophosphates, sul fi des, and cyanides), of organometallic compounds, and other derivatives of alkali metals, such as acetylenides, am-ides, hydrides, nitrides, and azides, can be considered as a mode of preparation of corresponding alcoholates, whereas the alcoholysis of hydroxides is one of industrial methods of producing potassium and sodium alcoholates:
