摘要： In order to recover methacrolein and/or methacrylic acid by quenching a reaction product gas obtained by catalytic oxidation of isobutylene or the like, the reaction product gas is charged into a quench column through a double-wall pipe and is then brought into contact with a condensate as a cooling medium. Deposition of terephthalic acid and the like inside the column is prevented by controlling the temperature of a bottom in the quench column and that of an overhead gas of a quench column unit. An aromatic carboxylic acid, aromatic aldehyde, metal powder is added to an aqueous solution of methacrylic acid, which contains terephthalic acid and the like, so that the terephthalic acid and the like are caused to precipitate for their removal.

摘要： In a process for preparing a Diels-Alder addition product of a conjugated diolefin and acrylonitrile by reacting the conjugated diolefin with acrylonitrile, a vessel type reactor is used. The pressure of the gaseous phase in the reactor is increased by using an inert gas in the reaction. A premixed solution of the conjugated diolefin or a compound which produces the conjugated diolefin in the reactor and acrylonitrile is released through an upper portion of the reactor into the gaseous phase and then dropped into a liquid phase to react. A reaction product is taken out through a lower portion of the reactor. The process can be carried out continuously in a safe manner over an extended period of time without any adhesion of an insoluble polymer to the reactor or to the inlet or outlet pipes, and without sudden pressure fluctuations.
