| description | PROBLEM TO BE SOLVED: To provide an improved process of producing (meth)acrylic acid.SOLUTION: There is provided a method of producing (meth)acrylic acid in which (meth)acrylic acid is recovered, and water and acetic acid are removed using a coupled, two tower purification system, wherein the water, acetic acid, and/or (meth)acrylic acid content of the system is monitored by using an on-line, near infrared (IR) spectroscopy comprising a pipe 26 equipped with a probe or a flow cell by creating an electronic signal based on at least one of the water, acetic acid, and/or (meth)acrylic acid content of at least one of (i) a tails stream 16 from the base of a first distillation tower 10, (ii) a condensed lights stream 7 from a condenser 13 which is coupled to the first distillation tower 10 and receives an overhead stream from the first distillation tower 10, and (iii) an overhead stream from a second distillation tower 17.SELECTED DRAWING: Figure 1
【課題】改良された（メタ）アクリル酸の製造方法の提供。【解決手段】連結された、二塔蒸留システムを用いて（メタ）アクリル酸を回収し、水及び酢酸を除去する（メタ）アクリル酸の製造方法であって、（ｉ）第一蒸留塔１０の底部からの残流１６、（ｉｉ）第一蒸留塔１０に連結され、第一蒸留塔１０から塔頂流を受ける凝縮器１３からの凝縮された軽質物流れ７、及び（ｉｉｉ）第二蒸留塔１７からの塔頂流の少なくとも一つの、水、酢酸及び／又は（メタ）アクリル酸の少なくとも一つの含有量に基づく電子シグナルを生成することにより、プローブ又はフローセルが取り付けられた配管２６を含むオンライン、近赤外線（ＩＲ）分光計を用いて、水、酢酸、及び/又は（メタ）アクリル酸のシステムの含有量をモニタリングする、（メタ）アクリル酸の製造方法。【選択図】図１ |
