  • Patent number: 9334224
    Abstract: This invention relates to a process for the preparation of alkenoic acid esters comprising contacting a lactone with an alcohol and an acidic catalyst in the gas phase, characterized in that the process is carried out in the presence of at least 0.26 wt. % water, relative to the amount of the lactone. The process may result in a good production yield and selectivity with respect to the production of alkenoic acid esters and may also result in less formation of dialkylethers. The improved yield advantageously allows energy conservation.

  • Patent number: 9227899
    Abstract: Propylene glycol methyl ether is produced by feeding a solution of a basic catalyst in methanol to a catalytic distillation column containing a heterogeneous basic catalyst defining a heterogeneous reaction zone, and feeding propylene oxide to the column. The methanol reacts with the propylene oxide according to a dual homogeneous catalytic reaction and heterogeneous catalytic reaction to form propylene glycol methyl ether, which is removed from the column as a bottoms product. Alternatively, methanol can be reacted with propylene oxide in a pre-reactor, to form propylene glycol methyl ether, and, when the temperature in the pre-reactor reaches about 100° C., the reaction products are transferred to the catalytic distillation column for further reaction.

  • Patent number: 9199862
    Abstract: Disclosed are an adsorption process whereby a fluorocarboxylic acid having an ether bond can be adsorbed to a high extent by using active carbon without changing the form thereof, and a desorption process whereby the adsorbed material can be desorbed from the active carbon to thereby enable the reuse of the active carbon and the adsorbed material. In the aforesaid processes, a solution containing a fluorocarboxylic acid having an ether bond is contacted with active carbon and thus the active carbon is allowed to adsorb the fluorocarboxylic acid, to thereby give a solution having a small fluorocarboxylic acid content. Then, the active carbon having adsorbed the fluorocarboxylic acid is heated to thereby desorbs the fluorocarboxylic acid from the active carbon.
