Popis: 1. The possibility was investigated of the replacement of isopentane by nitrogen as a phlegmatization diluent for acetylene in its condensation with cyclopentadiene in a flow apparatus, and it was shown that the yield of norbornadiene is maintained at its former level. 2. An investigation was made of the relation of the yields of norbornadiene and by-products to temperature in the range 250–375‡, to pressure in the range 7–17 atm excess, and to space velocity for the feed of cyclopentadiene in the range 0.05–1.1 h−1. It was found that the optimum conditions for the process are: temperature 340‡, pressure 13 gage atm, rate of feed of cyclopentadiene 0.25 h−1. The yield of norbornadiene is then 65% on the cyclopentadiene that reacts. 3. The amount of resinous products formed in the reactor does not depend on whether isopentane or nitrogen is used as diluent and is about 0.5% on the amount of cyclopentadiene passed.
