<Summary of Awarded Invention>
“PROCESS FOR PRODUCING ACETIC ACID” (Japanese Patent Number: 5662269)
Hiroyuki Miura, Masahiko Shimizu, Takashi Ueno, Kazuo Yamaguchi, Kensuke Goto
This invention relates to a process for producing acetic acid as a result of the reaction of methanol with carbon monoxide, which efficiently removes the reaction heat by condensing a portion of the vaporized material in the evaporator and recycling it to the reactor. This process allows the apparatus such as the distillation column to be miniaturized, inhibits loss of the carbon monoxide and will also enable the production of acetic acid in a resource and energy efficient manner.
