Embodiment 1

[0248] Embodiment 1: the etherification reaction of allyl alcohol

[0249] Etherification of allyl alcohol was carried out by using a glass autoclave reaction apparatus (HYPERGLASSTERTEM-V1000N, manufactured by Taiatsu Techno Co., Ltd.) having a volume of 1 L equipped with a stirring shaft coated with Teflon (registered trademark) and a thermocouple for measuring the internal temperature reaction. Into this reactor were charged 350 g (6.03 mol) of allyl alcohol and 10.28 g (60.3 mmol) of copper(II) chloride dihydrate (manufactured by Wako Pure Chemical Industries Co., Ltd., guarantee reagent). The reactor was sealed and an air tightness test was performed using nitrogen to verify that there were no leaks in the system. Thereafter, the pressure in the system was returned to atmospheric pressure, stirring was performed at a rotation speed of 350 rpm, and the power of the heater outside the reactor was turned on to start heating. The time point when the temperature inside the...

Embodiment 2

[0253] Embodiment 2: the etherification reaction of allyl alcohol

[0254] This process was repeated in the same manner as in Example 1, except that the etherification reaction was performed at a reaction temperature of 155° C., and the reaction time was changed to 2.0 hours. The reaction results are shown in Table 1 above.

Embodiment 3

[0255] Embodiment 3: the etherification reaction of allyl alcohol

[0256] The process was carried out in the same manner as in Example 1, except that the amount of copper(II) chloride dihydrate used was 30.84 g (180.9 mmol), and the reaction time was changed to 1.0 hour. The reaction results are shown in Table 1 above.

Abstract

A process for producing allylic ether compounds in presence of a catalyst comprising at least one Cu(II) salt by reaction of an allylic alcohol with either itself or another alcohol.

Description

[0001] This application claims priority to US Provisional Application 60 / 388,735, filed June 17,2002. technical field [0002] The present invention relates to a catalyst containing a divalent copper compound which can be used in an etherification reaction, and also relates to a method for preparing an ether compound by using the catalyst, and an ether compound obtained by the preparation method. [0003] More specifically, the present invention relates to a catalyst comprising a divalent copper compound, which can be used for the etherification reaction between an alcohol compound and a compound having at least one hydroxyl group in the molecule, or for an ether compound and a compound having at least one hydroxyl group in the molecule An etherification reaction between compounds with a hydroxyl group; and relates to a method for preparing an ether compound, which includes making an alcohol compound undergo an etherification reaction in the presence of the catalyst or making a...
