摘要:
A method for producing a dimerized aldehyde, which comprises subjecting a feed aldehyde to a condensation reaction and a dehydration reaction in the presence of a basic catalyst, wherein the feed aldehyde is the one having one or two hydrogen atoms at the .alpha.-position, an organic feed stream containing the feed aldehyde is supplied to a reactive distillation column, and the condensation reaction and the dehydration reaction are carried out simultaneously in the reactive distillation column.
摘要:
A DRAM control circuit, having a second counter 12 which counts the number of times of generation of a refresh request signal generated by a first timer circuit 100, a set value register 13 which holds the maximum number of reservations for refreshing a DRAM 52, and a second comparator 14 which compares the count value of the counter 12 and a value held by the set value register 13, which cancels high-speed page mode and refreshes the DRAM 52 in a predetermined procedure only at a time when the second comparator 14 detects coincidence between the count value of the second counter 12 and a value held by the set value register 13. This configuration enables it to limit refreshing during high-speed page mode, while achieving a DRAM control circuit capable of operating in high-speed page mode more efficiently.
摘要:
A method for producing an aldehyde, which comprises reacting an olefin with carbon monoxide and hydrogen in a hydroformylation reaction zone in the presence of a rhodium catalyst having an organophosphorus compound as a ligand, wherein a reaction solution withdrawn from the hydroformylation reaction zone, which contains an unreacted olefin, an aldehyde product and the catalyst, is countercurrently contacted with carbon monoxide and hydrogen in a contact tower to separate and recover the unreacted olefin without substantially deactivating the rhodium catalyst and supplying the recovered unreacted olefin together with the carbon monoxide and the hydrogen to the hydroformylation reaction zone.
