Bismuth reactivity with water
WebAn important side reaction involves the isocyanate component and water. If moisture is present in the mixture ( Figure 4 ), then the isocyanate will react with this water to form an unstable carbamic acid which then decomposes to form urea and carbon dioxide gas thus resulting in foaming.

Atmospheric carbon dioxide or CO2 dissolved in water readily reacts with Bi2O3 to generate bismuth subcarbonate. Bismuth oxide is considered a basic oxide, which explains the high reactivity with CO2. However, when acidic cations such as Si(IV) are introduced within the structure of the bismuth oxide, the reaction with CO2 do not occur. Bismuth(III) oxide reacts with a mixture of concentrated aqueous sodium hydroxide and bromin… WebUpon dissolution of the metabisulfite in water, bisulfite is regenerated: Na 2 S 2 O 5 + H 2 O → 2 Na + + 2 HSO 3 −. Sodium bisulfite is formed during the Wellman-Lord process. …
WebIn all cases, the phenyl group was found to migrate in preference to hydrogen. In contrast, using other Lewis acids such as BF 3 Et 2 O or MgBr 2, the reaction is not regioselective and gives a mixture of both diphenylacetaldehyde and deoxybenzoin (hydrogen migration).The rearrangement of α-pinene oxide 74 with bismuth(III) oxide perchlorate … WebApr 8, 2010 · perhaps bismuth perchlorate could be made by NH4ClO4 + (BiO)2CO3 > Bi (ClO4)3? + (NH4)2CO3 problem would be that this reaction would be easiest to make with water, as in mixing both reagents (aq) it could perhaps be done both in anhydrous state? they mention in the picture of the old book that it doesnt work when it gets anywhere …
