Furthermore, when producing dialkylhydroquinone using an a-olefin as the olefin, a sufficient yield cannot be obtained with these above-mentioned catalysts.
一方、これらの欠点を改良するものとして、特公昭46

しかしながら、この触媒を用いた場合には、より高い反
応温度が必要てあり、通常160°C以上の反応温度を
必要とし、工業的生産の場合には加熱を直火等で行わね
ばならず、特殊な装置が必要であった。However, when this catalyst is used, a higher reaction temperature is required, usually a reaction temperature of 160°C or higher, and in the case of industrial production, heating must be done with an open flame etc. Special equipment was required.
従って本発明の目的は、ハイドロキノンとオレフィンと

の製造方法を提供することにある。Therefore, an object of the present invention is to produce a dialkylhydroquinone by reacting hydroquinone with an olefin, which is simple and has a high yield, and which does not require any special equipment even in the case of industrial production. Our goal is to provide the following.

以下、本発明の詳細な説明する。The present invention will be explained in detail below.

ルハイドロキノンが得られ、本発明の効果がより一層顕
著に現れるからである。Among these olefins, a-olefins are preferred. The reason why it is preferable is that when using the strongly acidic polystyrene-based sulfonic acid type cationic resin according to the present invention, compared to using conventionally known catalysts such as aluminum chloride, sulfuric acid, hydrogen fluoride, boron trifluoride, etc. This is because dialkylhydroquinone can be obtained in a higher yield, and the effects of the present invention are even more pronounced.
a−オレフィンはエチレンの重合によって便宜に誘導さ
れ、従って主として偶数個の炭素原子を含むオレフィン
であり、例えば1−ヘキセン、l−オクテン、l−ドデ
セン、l−テトラデセン、l−へキサデセン、1−エイ
コセン等を挙げることができる。α-olefins are conveniently derived by the polymerization of ethylene and are therefore primarily olefins containing an even number of carbon atoms, such as 1-hexene, 1-octene, 1-dodecene, 1-tetradecene, 1-hexadecene, 1- Examples include eicosene and the like.
又、σ−オレフィンは混合物であってもよく、例えば混

a-olefin, mixed CIa to C1, α-olefin,
Mixed CI6-C3°σ-olefins and the like can be mentioned.
本発明で用いるオレフィンとハイドロキノンの割合は、
種々変動させることが可能であるが、好マシくはハイド
ロキノン1モルに対してオレフィン2〜3モルである。The ratio of olefin and hydroquinone used in the present invention is
Although it is possible to vary the amount, it is preferably 2 to 3 moles of olefin per 1 mole of hydroquinone.

Examples include commercially available strongly acidic polystyrene-based sulfonic acid type cationic resins such as HD (manufactured by Mitsubishi Kasei), Bayer 24411, Bayer 2641, and Bayer 1481 (all manufactured by Bayer).
強酸性ポリスチレン系スルホン酸型カチオン樹脂の粒子
径が0.2mm以下であると、より高収率で目的とする
ジアルキルハイドロキノンが得られるので特に好ましい
。この理由は明確には判らないが、恐らく粒子径が小さ
くなる事によって表面積が増大し、そのため用いられる
オレフィンを効率よく活性化するためではないかと考え
られる。It is particularly preferable that the particle size of the strongly acidic polystyrene-based sulfonic acid type cationic resin is 0.2 mm or less, since the desired dialkylhydroquinone can be obtained in a higher yield. Although the reason for this is not clearly known, it is thought that the surface area increases as the particle size decreases, and as a result, the olefin used is efficiently activated.
