    • Provided is a catalyst for adding a glycidyl ether to an active hydrogen-containing organic compound, comprising a complex oxide of magnesium and at least one element other than magnesium selected from the group consisting of the elements in the third period and the fourth period in the periodic table. Also provided is a process for producing a glycidyl ether adduct, which comprises subjecting an active hydrogen-containing organic compound and a glycidyl ether to an addition reaction in the presence of the above-mentioned catalyst. In the addition reaction between the active hydrogen-containing organic compound and the glycidyl ether, use of the catalyst of the present invention enables inhibition of an excess addition reaction of the glycidyl ether which is a successive reaction, and a mono- or di-(alkyl, alkenyl or phenyl) ether product in which one or two glycidyl ethers are added is selectively produced by adjusting the mole ratio of the active hydrogen-containing organic compound to the glycidyl ether to a specific range. Accordingly, the mono- or di-(alkyl, alkenyl or phenyl) ether product can be obtained at a high productivity with a high purity.
    • 提供了一种用于向含活性氢的有机化合物中加入缩水甘油醚的催化剂,其包含镁和至少一种除镁以外的元素的复合氧化物,所述复合氧化物选自第三周期和第四周期中的元素组 周期表。 还提供了一种制备缩水甘油醚加合物的方法,其包括在上述催化剂存在下使含活性氢的有机化合物和缩水甘油醚进行加成反应。 在含活性氢的有机化合物和缩水甘油醚之间的加成反应中,使用本发明的催化剂可以抑制作为连续反应的缩水甘油醚的过量加成反应,以及单 - 或二 烷基,烯基或苯基)醚产物,其中加入一个或两个缩水甘油醚是通过将含活性氢的有机化合物与缩水甘油醚的摩尔比调整到特定范围来选择性地制备的。 因此,可以以高纯度的高生产率获得单 - 或二 - (烷基,烯基或苯基)醚产物。

    • An aluminum compounds represented by the following general formula (1): Al(R1—SO3)1(R2)m(R3)n   (1) wherein R1 is a hydrocarbon group which may be substituted, R2 is a hydrocarbon group which may be substituted, an aliphatic hydrocarbonoxy group which may be substituted, or a halogen atom, R3 is an aromatic hydrocarbonoxy group which may be substituted, and 1, m and n are independently a number of 0 to 3, with the proviso that 1+m+n equals 3, and 1 is not 0, an acid catalyst comprising the aluminum compound, and a process for producing an ester, acetal, ketal, ether or alkyl glycoside making use of the catalyst. The catalyst is suitable for use in a variety of acid-catalyzed reactions of alcohols, i.e., reactions with carbonyl compounds, such as esterification, transesterification, acetalization and ketalization, etherification, ring-opening reactions of epoxy compounds, etc. in addition to the above-described respective reactions, is not deactivated by alcoholysis, has a sufficient activity, can easily control a reaction catalyzed thereby and scarcely causes side reactions. Consequently, the use of the catalyst permits the production of the intended product at a high yield from starting materials used in an almost equimolar proportion.
    • 由以下通式(1)表示的铝化合物:其中R1是可被取代的烃基,R2是可被取代的烃基,可被取代的脂族烃氧基或卤素原子,R3是 可以被取代的芳族烃氧基,并且1,m和n独立地为0-3的数,条件是1 + m + n等于3,并且1不为0,包含铝化合物的酸催化剂, 以及利用催化剂生产酯,缩醛,缩酮,醚或烷基糖苷的方法。该催化剂适用于各种酸催化的醇反应,即与羰基化合物的反应,如酯化, 酯交换,缩醛化和缩酮化,醚化,环氧化合物的开环反应等除了上述各自的反应之外,不通过醇解使其失活,具有足够的活性,可以容易地控制ar 因此催化,并且几乎不引起副反应。 因此,使用催化剂允许以几乎等摩尔比例使用的起始材料从高产率生产所需产品。
