Henry's Law Constants for t-Butyl Chloride in Aqueous Methanol Solutions

Abstract

Notes 5255 not proceed by the primary mechanism alone. Drops of diethyl phthalate have been identified in the decomposition apparatus, which suggests dissociation according to equation 7 ZrCl4-C«H4(COOC2H5)2-> ZrCh + CelLCCOOCiHsh (7)It is possible that the ethylene results from the decomposition of the ester, as reported for ethyl benzoate.1 2345 *If this is so, the phthalic acid, resulting from equation 8, would react with any free metal tetrachloride to give hydrogen chloride.C6H4(COOC2H5)2 ->-C6H4(COOH)2 + C,H4 (8) ZrCl4 + C,H4(COOH)2 -*-ZrCl2(OOC)2CtH4 + 2HC1 (9) In the zirconium case only, trace quantities of phthalic anhydride were identified among the decomposition products.Acknowledgment.-This work was supported in part by the U.
