phloroglucine is about 180 to 220 DM per kg A new way of synthesis would be interesting for this valuable product As, however, the worldwide need in phloroglucine is about 150 to 200 annual tons, provision of 15 to 20 million DM investment funds required for the

Title Reactions of Ketene with Phenol, Resorcine

The reactions of ketene with phenol, resorcine, phloroglucine and dimedone have been studied (1) Without catalyst, ketene gave always 0-acetyl derivatives of them (2) With sulfuric acid, pyridine or sodium acetate as catalyst, 0-acetyl de- Table 1
