“…of mercury), (2) 22-hour period at 302°C. and constant flow rate, (3) four feed rates at 302°C ., (4) four feed rates at 318 °C., (5) four feed rates at 339°C ., (6) four feed rates at 358°C ., (7) two feed rates at 339°C ., (8) two feed rates at 318°C ., and (9) two feed rates at 302°C. Each condition of temperature and feed rate was maintained for 4 hours.…”

“…Furthermore, studies of olefin and ether formation have not. been reported for the higher normal aliphatic primary alcohols, although several studies on the dehydration of such alcohols to olefins appear (8,4,8).…”
