After this period of time, further treating did not increase the amount of furfuraldehyde produced.    From Wordnik.com.  [Scientific American Supplement, No. 821, September 26, 1891] Reference

The percentage yields of furfuraldehyde obtained from these fractions were as follows: A, insoluble, 0.86; precipitated, 4.35; dissolved, 1.10.    From Wordnik.com.  [Researches on Cellulose 1895-1900] Reference

The neutral or very faintly alkaline solution was then distilled almost to dryness, when practically the whole of the furfuraldehyde comes over.    From Wordnik.com.  [Scientific American Supplement, No. 821, September 26, 1891] Reference

The tint obtained with the standard was then compared with that yielded by the gum distillate from which the respective ratios of furfuraldehyde are obtained.    From Wordnik.com.  [Scientific American Supplement, No. 821, September 26, 1891] Reference

From these and some other substances, the following percentage yields of furfuraldehyde were obtained: Hydrocellulose, 0.854; oxycellulose, 2.113; reduced cellulose.    From Wordnik.com.  [Researches on Cellulose 1895-1900] Reference

The yields of furfuraldehyde would appear to have no definite relation to the other chemical data about a gum, such as the potash and baryta absorptions or the sugar produced on inversion.    From Wordnik.com.  [Scientific American Supplement, No. 821, September 26, 1891] Reference

The yield of furfuraldehyde by the breaking down of arabin and metarabin was thought possibly to be of some value in differentiating the natural gums from one another, but we have not succeeded in obtaining results of much value.    From Wordnik.com.  [Scientific American Supplement, No. 821, September 26, 1891] Reference

It appears, from the foregoing results, that the cellulose molecule, after oxidation, is easily decomposed by potash, the insoluble and larger portion having all the characters of the original cellulose, whilst the soluble portion is of an aldehydic nature, and contains a substance, precipitable by acids, which yields a relatively large amount of furfuraldehyde.    From Wordnik.com.  [Researches on Cellulose 1895-1900] Reference

That portion of the carbohydrates known as pentosans gives rise to furfuraldehyde, one of the important components of caffeol.    From Wordnik.com.  [All About Coffee] Reference

Although furfuraldehyde is the natural decomposition product of pentosans, furfuryl alcohol is the main furane body of coffee aroma.    From Wordnik.com.  [All About Coffee] Reference

The chemical the friend wanted to produce, furfuraldehyde alcohol, is made from corncobs and used in pharmaceuticals and steel foundries, things Lohia knew nothing about.    From Wordnik.com. Reference

He considers the roasting of coffee as a destructive distillation process, summarizing the results, briefly, as the production of furfuraldehyde from the carbohydrates, acrolein from the fats, catechol and pyrogallol from the tannins, and ammonia, amins, and pyrrols from the proteins.    From Wordnik.com.  [All About Coffee] Reference
