Description

【特許請求の範囲】
【請求項１】 スズ化合物（Ｃ１）を触媒として原料の（メタ）アクリル酸アルキルエステル（Ｅ１）とモノアルコール（Ａ１）とをエステル交換反応（Ｒ１）させ、得られた反応液から蒸留により目的とする（メタ）アクリル酸エステル（Ｔ１）を留出させて取得し、その際に得られるスズ化合物を含む蒸留残渣（Ｃ２）を触媒として原料の（メタ）アクリル酸アルキルエステル（Ｅ２）とモノアルコール（Ａ２）とをエステル交換反応（Ｒ２）させ、目的とする（メタ）アクリル酸エステル（Ｔ２）を取得する（メタ）アクリル酸エステルの製造方法において、次の（１）〜（３）の特徴を有する（メタ）アクリル酸エステルの製造方法。
（１）前記エステル交換反応（Ｒ１）中の反応液に含まれる水分量を前記スズ化合物（Ｃ１）に含まれるスズ原子１モルに対して０．０００１〜５モルにする。
（２）前記蒸留残渣（Ｃ２）に含まれる水分量を、前記エステル交換反応（Ｒ２）に使用するまでの期間、スズ原子１モルに対して０．０２〜５モルにする。
（３）前記エステル交換反応（Ｒ２）中の反応液に含まれる水分量を前記蒸留残渣（Ｃ２）に含まれるスズ原子１モルに対して０．０００１〜５モルにする。 [Claims]
1. A transesterification reaction (R1) between a raw material alkyl (meth) acrylate (E1) and a monoalcohol (A1) using a tin compound (C1) as a catalyst, and the reaction mixture obtained is subjected to distillation by distillation. The (meth) acrylic acid ester (T1) is distilled off and obtained, and the distillation residue (C2) containing a tin compound obtained at that time is used as a catalyst and the raw material (meth) acrylic acid alkyl ester (E2) is used as a catalyst. In the method for producing a (meth) acrylic acid ester, which obtains a desired (meth) acrylic acid ester (T2) by subjecting the alcohol (A2) to a transesterification reaction (R2), the following (1) to (3) A method for producing a (meth) acrylic acid ester having characteristics.
(1) The amount of water contained in the reaction solution in the transesterification reaction (R1) is set to 0.0001 to 5 mol per 1 mol of tin atom contained in the tin compound (C1).
(2) The amount of water contained in the distillation residue (C2) is adjusted to 0.02 to 5 mol with respect to 1 mol of tin atom until it is used in the transesterification reaction (R2).
(3) The amount of water contained in the reaction solution in the transesterification (R2) is set to 0.0001 to 5 mol per 1 mol of tin atoms contained in the distillation residue (C2).
