WebA variety of bismuth compounds have been used in organic transformations over the last 10–15 years because of their low toxicities, a wide range of reactivities, and low cost.62 Catalytic quantities of bismuth (III) compounds are effective in promoting the rearrangement of epoxides to carbonyl compounds. WebSep 26, 2000 · Acid values of the polyol components were monitored along with surface dry of cast films. A slight decrease in acid value was noted (from 4.5 to 3.7) as the dry time increased (see Figure 7) in the system without 2,4-pentanedione. Acid value of the system with 2,4-pentanedione remained constant while only a slight increase in dry time was noted.
