[×ÊÔ´] The Chemistry and Technology of Furfural and its Many By-Products

Elsevier Science |
ISBN:   044450351X

PDF | 374 pages

This book is a "world first", since the furfural industry has beentraditionally secretive to the point of appearing shrouded in clouds ofmystery. Even renowned encyclopedic works have published but scant andoften erroneous information on the subject.
                     
Striking a healthy balance between theory and practice, the book leadsthe reader from reaction mechanisms and kinetics to the technology ofmaking furfural by various old and new processes, using conventionalraw materials or sulfite waste liquor. Detailed discussions of means ofincreasing the yield are of great chemical and technological interestas well as of immense economic importance.
                     
From furfural proper, the treatise shifts to the fascinating field ofwanted and unwanted by-products ranging from largely unutilizedcarboxylic acids to troublesome impurities such as 5-methyl furfuraland 2-furyl methyl ketone, and then to extremely valuable serendipitousflavor compounds such as diacetyl and 2,3-pentanedione. A wide varietyof derivatives are discussed; considerable space is devoted topolytetrahydrofuran, an important building block of stretchablesynthetic fibers, while furan resins from both furfural and furfurylalcohol are given the attention commensurate with their industrialimportance.
                     
Notable supplementary chapters cover the in-line measurement offurfural, the treatment of furfural waste water, and various aspects ofcorrosion. A chapter on the applications of furfural elaborates notonly traditional uses in extracting petroleum and vegetable oils butalso the sensational discovery that furfural is a highly effective"indirect nematocide". Without becoming toxic, it changes themicroflora of the soil by stimulating bacteria antagonistic tonematodes, thereby reducing the nematode population to zero, at anunprecedented low price. It is believed that this application will bethe principal outlet for furfural in the future.
                     
A comprehensive list of physical properties, some never publishedbefore, make the book an indispensable companion for producers, usersand researchers alike
