Furfurol

(furf-fu-rol). The aldehyd of furfuryl alcohol is produced in the distillation of bran with dilute or of sugar, etc. It is also derived from arabinose or xylose and occurs in the decomposition-products of albuminoid bodies, as meat, cheese, urine, etc. With phenyl hydra zin it forms a nearly insoluble compound, furfurol hydrazon. It is a colorle volatile oil, with an aromatic odor. Its specific gravity at 1300 C. is 1.163. It boils at 1620 C. It combines with dimethyl anilin to form a green dye-stuff, corresponding to malachite green. It exists in certain new whiskies; but as the spirit becomes older the furfurol gradually disappears.
