EXCESS MOLAR VOLUMES OF BINARY-MIXTURES OF ALKYL ACETATES WITH HEXANE, TETRACHLOROMETHANE, AND TRICHLOROMETHANE

Excess molar volumes VE have been determined from density rho measurem ents, using a vibrating-tube digital densimeter DMA 60/602 for binary mixtures of methyl acetate (MA), ethyl acetate (EA), and n-amyl acetat e (n-AA) with n-hexane (C6H12), tetrachloromethane (CCl4), trichlorome thane (CHCl3) and of iso-amyl acetate (i-AA) with CCl4, and CHCl3. The results we refitted to the polynomial relations to obtain the coeffic ients and the standard deviations. The results have been analyzed in t erms of disruption of dipolar association of alkyl acetates and molecu lar interactions between alkyl acetate and chloromethane. (C) 1998 Els evier Science B.V.
