PRODUCTION OF STABILIZED ALUMINUM BROMIDE SOLUTIONS

摘要

Stabilized solutions of aluminum bromide in cyclohexane are produced by adding 0.5 - percent by volume of benzene or 0.5 - 2 percent by weight of triphenol [1,1,3(3-hydroxyphenyl) propane]. The rapid degradation of unstabilized solutions at room temperature is markedly retarded for a period of at least 30 days so that the solutions may be shipped and stored and used instead of solid aluminum bromide as a Lewis acid type catalyst.
