Show Dallas Texas Coal Coal tar highly valuable raw material by which organic organic organic or or- ganic chemists fashion scores of synthetic chemical products has a anew anew anew new rival in lignin tar obtained from cornstalks it was v indicated in the report to the chemists' chemists meeting here of G. G Leon Bridger of the chemical chemical chem chem- ical engineering department of Iowa State Stale university Synthetic resins plastics drugs dyes perfumes and flavors may be manufactured in the future from agricultural materials like corn corn- st stalks B By digesting cornstalks with strong alkalis like ordinary lye inthe Inthe in hi hithe the absence of air a black tar is produced which is somewhat similar to coal tar It is however far richer rich rich- er in phenols Moreover the yield of tar is much greater and as a result about 40 times as much phenols phenols phe phe- riols are obtained from a pound of lignin as from a pound of coal The preparation of phenols from rom the by destructive distillation was discovered by Dr Max Phillips of the United States Department of Agriculture |
