Studies in the Terpene Series. IX.¹ Isomerization Accompanying Cycloalkylation of Benzene²

Isomerization

“…The isomerization of acetylenic hydrocarbons with metal oxide catalysts has been the subject of a series of Russian articles, of which the most recent one is listed (24). Isomerization reactions accompanying alkylation have been discussed in a number of interesting papers (17,18,23,26,37,38).…”

“…The Du Pont Co. also plans to install a similar unit in an explosives factory to be built near Martinsburg, W. Va. The Biazzi continuous nitration and washing process (17) for making nitroglycerin will be used by Canadian Industries, Ltd., and Du Pont. This process has been in use in several countries in Europe for a number of years and it was referred to in earlier reviews (18,19).…”

“…It has been pointed out (17) that the main advantage of the Biazzi process over the batch process is its safety factor, as only a relatively small quantity of explosive material is in process at any one time. In case of an accident, this reduces to a minimum the possibility of the communication of explosion to other buildings and the damage to property.…”
