In the investigated threefold stratified systems, except for systems with methanol and ethanol, there is an interaction between dinitrates diantipyrylmethahiy and alcohol. In solvat molnoe the attitude {relation} salt : alifaticheskiy alcohol 1:1 and salt : benzilloviy alcohol 2:1. Solubility solvate decreases with growth moliar weights of spirit. Since oktilovago alcohol the branch of crystallization solvate lays below critical point binodalnoi a curve that results in formation of the second area monotektichescoi balance of crystals solvate and two mutually sated liquids. Because of development of a field of crystallization solvate the area of stratification which in system with decilovai alcohol disappears in general is narrowed. Systems with metanol, etanol, butanol it is impossible to count threefold because of solivoliz salts, and it is necessary to consider as a diagonal cut of fourfold systems diantipyrylmethah nitric acid benzyl alcohol.
