である。(Structure of the Invention) That is, the present invention provides the following general formula (I) [wherein R represents a hydrogen atom or a methyl group.
以下に本発明の(メタ)アクリレート化合物の製造方法
について詳述する。The method for producing the (meth)acrylate compound of the present invention will be described in detail below.
反応出発原料である3、4−エポキシシクロヘキサンメ
タノールは以下のような構造式で示され、無色透明、蒸
気圧130℃/ 10 T 。3,4-Epoxycyclohexanemethanol, which is a starting material for the reaction, has the following structural formula, is colorless and transparent, and has a vapor pressure of 130°C/10T.
rrの性状を有する環式アルコールであり、エポキシ樹
脂の原料などに用いられている。It is a cyclic alcohol with the properties of rr, and is used as a raw material for epoxy resins.
工業的にはテトラヒドロベンジルアルコールを有機過酸
でエポキシ化させることにより製造されている。Industrially, it is produced by epoxidizing tetrahydrobenzyl alcohol with an organic peracid.
一方、アクリル酸はアクリロニトリルを硫酸で加水分解
するすることにより工業的に大量に製造されている。On the other hand, acrylic acid is industrially produced in large quantities by hydrolyzing acrylonitrile with sulfuric acid.
また、メタクリル酸はメタクリル酸メチルを製造する際
の副生物として得られている。In addition, methacrylic acid is obtained as a by-product during the production of methyl methacrylate.
これらアクリル酸、メタクリル酸は各種樹脂、ポリマー

リル酸は無色の酢酸に類似した液体で沸点141.7℃

9〜163℃の液体である。これらは共に重合しやすい
。These acrylic acid and methacrylic acid are common monomers used as homopolymerization or copolymerization monomers when manufacturing various resins, polymer emulsions, etc. Acrylic acid is a colorless liquid similar to acetic acid with a boiling point of 141.7°C.
, soluble in water, methacrylic acid is colorless and transparent with a boiling point of 15
It is a liquid with a temperature of 9 to 163°C. Both of these are likely to polymerize.

水を連続的に系外へ取り出すことにより反応は促進され
る。3.4-Epoxycyclohexane methanol and (meth)
When a (meth)acrylate compound is produced by esterification with acrylic acid, the reaction is accelerated by using a catalyst and continuously removing the produced water from the system.
反応をバッチで行なう場合は先ず、反応容器内に3.4
−エポキシシクロヘキサンメタノールを所定量仕込み、
この中に前記好適量の触媒を溶解させ、この中にアクリ
ル酸またはメタクリル酸を仕込み、行なう。When carrying out the reaction in batches, first add 3.4 ml to the reaction vessel.
-Preparing a predetermined amount of epoxycyclohexane methanol,
The suitable amount of the catalyst is dissolved in this, and acrylic acid or methacrylic acid is charged therein.
3.4−エポキシシクロヘキサンメタノールと(メタ)
アクリル酸とのエステル化反応におけるモル比は理論的
には1/1であるが、本発明などのように実際には1/
10〜10/1の範囲、好ましくは1/1〜1/3の範
囲である。3.4-Epoxycyclohexane methanol and (meth)
The molar ratio in the esterification reaction with acrylic acid is theoretically 1/1, but in reality, as in the present invention, it is 1/1.
It is in the range of 10 to 10/1, preferably in the range of 1/1 to 1/3.
エステル化反応のモル比が3,4−エポキシシクロヘキ
サンメタノール/(メタ)アクリル酸−1/10未満の
場合は3.4−エポキシシクロへ午サンメタノールの選
択率および転化率の点で好ましいが、アクリル酸または
メタクリル酸自身の重合による損失が大きく、また、未
反応のアクリル酸またはメタクリル酸の回収に多大の費
用を要する、などの欠点がある。If the molar ratio of the esterification reaction is less than 1/10 of 3,4-epoxycyclohexane methanol/(meth)acrylic acid, it is preferable in terms of the selectivity and conversion rate of 3,4-epoxycyclohexane methanol. There are drawbacks such as large losses due to polymerization of acrylic acid or methacrylic acid itself, and large costs required to recover unreacted acrylic acid or methacrylic acid.
逆にエステル化反応のモル比が3.4−エポキシシクロ
ヘキサンメタノール/(メタ)アクリル酸−10/1を
越える場合はアクリル酸またはメタクリル酸の重合によ
るロスは減少するが、3゜4−エポキシシクロヘキサン
メタノールの回収に多大のエネルギーを要するので好ま
しくない。Conversely, when the molar ratio of esterification reaction exceeds 3.4-epoxycyclohexane methanol/(meth)acrylic acid - 10/1, the loss due to polymerization of acrylic acid or methacrylic acid decreases, but 3.4-epoxycyclohexane methanol/(meth)acrylic acid This is not preferred because it requires a large amount of energy to recover methanol.
ここで使用する触媒は硫酸、p−トルエンスルホン酸、
三フッ化ホウ素等の通常用いられているエステル化触媒
として公知のものから任意に選択して使用することがで
