Description
本発明は、炭素数４以上の環式骨格を有するアルコール（以下、これを環式骨格含有アルコールと略称する）と（メタ）アクリル酸またはその反応性誘導体を反応させる工程、および該工程で得られる反応生成物を、アンモニアまたはアミン類を含む洗浄液で洗浄する工程を含むことを特徴とする環式骨格含有（メタ）アクリル酸エステルの製造方法である。 The present invention provides a process of reacting an alcohol having a cyclic skeleton having 4 or more carbon atoms (hereinafter abbreviated as a cyclic skeleton-containing alcohol) with (meth) acrylic acid or a reactive derivative thereof, and the process. The reaction product obtained is a method for producing a cyclic skeleton-containing (meth) acrylic acid ester comprising a step of washing with a washing liquid containing ammonia or amines.
次に、環式骨格含有アルコールと（メタ）アクリル酸またはその反応性誘導体との反応生成物の洗浄工程について説明する。
上記の工程で得られる反応生成物（反応混合物）は、アンモニアまたはアミン類を含む水溶液（洗浄液）で洗浄する。かかるアミン類としては、（メタ）アクリル酸またはその反応性誘導体や触媒、（メタ）アクリル酸由来のオリゴマーなどと反応して水溶性の化合物を与えるアミン類であればよく、例えばメチルアミン、エチルアミン、プロピルアミン、ブチルアミン、ジメチルアミン、ジエチルアミン、トリメチルアミン、トリエチルアミン、ピリジンなどを使用することができる。操作性を考慮すれば、洗浄液としては、アンモニア水、トリエチルアミンを含む水溶液を使用するのが好ましい。洗浄液中のアンモニアまたはアミン類の濃度は、１〜２５重量％の範囲であるのが好ましく、１〜１０重量％の範囲であるのがより好ましい。この洗浄処理により、反応混合物中に含まれる未反応原料［環式骨格含有アルコール、（メタ）アクリル酸またはその反応性誘導体］や触媒、（メタ）アクリル酸由来のオリゴマー、その他の水溶性不純物が効率よく除去される。
Next, the washing | cleaning process of the reaction product of cyclic skeleton containing alcohol and (meth) acrylic acid or its reactive derivative is demonstrated.
The reaction product (reaction mixture) obtained in the above step is washed with an aqueous solution (washing solution) containing ammonia or amines. Such amines, (meth) acrylic acid or a reactive derivative thereof and the catalyst may be a amine to give (meth) compounds such as reacting with the water-soluble oligomer derived from an acrylic acid, For example main ethylamine, Ethylamine, propylamine, butylamine, dimethylamine, diethylamine, trimethylamine, triethylamine, pyridine and the like can be used . Considering operability, as the cleaning liquid, aqueous ammonia is preferable to use an aqueous solution containing triethylamine. The concentration of ammonia or amines in the cleaning liquid is preferably in the range of 1 to 25% by weight, more preferably in the range of 1 to 10% by weight. By this washing treatment, unreacted raw material [cyclic skeleton-containing alcohol, (meth) acrylic acid or a reactive derivative thereof], catalyst, oligomer derived from (meth) acrylic acid, and other water-soluble impurities contained in the reaction mixture. It is efficiently removed.
