Specific gravity, apple

Ethyl Malonate.—Ethyl malonate is not a member of the parafiinoid acid esters, but is sufficiently nearly related to this series to be included here as a matter of convenience. It is of considerable value in modifying flower odours, having a more or less characteristic apple odour, but of a much sweeter type than the valerianic ester perfume. It is an oil of specific gravity 1 068, and boils at 198°.

This generally easy-to-ignite plastic burns with a yellow flame with a faint odor of apple. It produces black smoke. Thermoplastic polyurethane is soluble in tetrahy-drofuran and dimethyl formamide. The specific gravity of this material is 1.2.
