The extraction equilibria of chromium(VI) from sulfuric acid solutions with tri-n-octylphosphine oxide (TOPO) dissolved in kerosene at 25Β‘C have been studied. The possible complexes of chromium(VI) with TOPO in organic phase and extraction constants were determined by best Γtting the distribution co
## Contrary to the literature that isoprene was dimerieed to the mixture of dipentene and sn aliphatic dimer in the presence of sulfuric acid (l), we can now report that the major products in this reaction are unsaturated and saturated cyclic ethers. In our experiments, isoprene was stirred at 20
