text: Usually, however, normal butane represents only a comparatively small percentage of a butadiene-containing mixed hydrocarbon stream, and since the azeotrope is the minimum boiling type and, therefore, boils at a lower temperature than butadiene, it would appear that by taking slightly more butadiene overhead than required to form the azeotrope with the normal butane present, the normal butane could be eliminated from the butadiene retained in the bottom product.
