Apparatus Description
The apparatus adapted for the generation of ketene is a modification of the conventional apparatus for ketene generation [9, 10], were the electrical chamber was replaced by a thermal chamber. The use of metals and thermal chamber provides a short contact time for ketene generation and subsequent high yield attributed to close packing of metals in 2 mm internal diameter and 3 cm long packing in a Pyrex glass combustion tube than conventional apparatus whose filament is 70 cm long and sealed in a Pyrex glass 25 cm long and 70 mm internal diameter. The novelty in this work is that, the use of metals and thermal chamber provides a shorter contact time for ketene generation and subsequent high yield attributed to close packing of metals in 5 mm internal diameter and 3 cm long packing in a Pyrex glass combustion tube than conventional apparatus whose filament is 70 cm long, sealed in a Pyrex glass 25 cm long with 70 mm internal diameter.
