WebApr 4, 2024 · It is a known fact that the bromobutyl rubber can form carbon-carbon crosslinks when it is heating with zinc oxide at a temperature greater than 160 °C. Generally, the rate of ZnO vulcanization is slow at this temperature. If any, attempt to enhance the rate of cure by rising the temperature will lead to an inferior state of cure. It has also been reported … WebZinc is the most efficient metal found to participate in the water-phase Barbier reaction. It could catalyze the allylation of carbonyl and carbonyl compounds as well as participate in the benzylation of carbonyl and some special alkylation. Also, zinc participates in carbon-oxygen and carbon-nitrogen double bond barrier reaction.
