Latest Patents

One of his latest patents is a method for producing α-hydroxycarboxylate. This invention provides a process for more efficiently producing an α-hydroxycarboxylic acid ester while inhibiting side reactions compared to prior art production processes. The method involves three steps: first, reacting a 1,2-diol with another 1,2-diol or an alcohol in the presence of oxygen; second, separating the α-hydroxycarboxylic acid ester from the reaction product through distillation under reduced pressure; and third, feeding the reaction with a mixture obtained by partially or entirely removing water from the reaction product.

Another significant patent is a method for the exchange of catalysts in a carbon steel shell and tube type reactor. This invention addresses the issue of rust formation on the internal surface of the tubes during catalyst exchange, which can lead to the formation of impurities such as aldehydes. The method involves maintaining the temperature of the internal surface of the tubes higher than the dew point during the catalyst exchange process.
