Identifying unknown liquid

A colorless liquid, bp = 199 - 201 degrees C, burns with a yellow, sooty flame.  The sodium fusion test proved negative for the presence of halogens, nitrogen, and sulfur. It was not soluble in water, 5% aqueous sodium hydroxide, or 5% hydrochloric acid. However, it dissolved in sulfuric acid with evolution of heat. It did not give a precipitate with 2,4-dinitrophenylhydrazine solution, and it did not decolorized bromine-methylene chloride solution. The unknown liquid did give a positive hydroxamate test and was found to have saponification equivalent of 136. Identify the unknown liquid.
