    • The present invention relates to a method and equipment for production of high purity silicon by reduction of SiCI4 with molten Zn metal. The method is characterized in that the reduction takes place in contact with a molten salt that dissolves ZnCI2. The ZnCI2 produced during the reduction then dissolves in the molten salt rather than evaporates. The advantage is that gas evolution during the reduction is minimised, leading to higher utilisation of the SiCI4 and Zn and thereby a higher Si yield. Another advantage is that the molten salt efficiently protects the air sensitive materials, Zn, SiCI4 and Si, from oxidation during the reduction. The resulting molten salt containing the ZnCI2 can be used for electrolysis of ZnCI2 to regenerate the Zn metal. Chlorine evolved during the electrolysis can be used to produce SiCI4.
    • 本发明涉及通过用熔融的Zn金属还原SiCl 4来生产高纯度硅的方法和设备。 该方法的特征在于还原与溶解ZnCl 2的熔融盐接触。 在还原期间产生的ZnCl 2溶解在熔融盐中而不是蒸发。 优点在于还原过程中的气体逸出最小化,导致SiCl 4和Zn的利用率提高,Si产率提高。 另一个优点是熔融盐有效地保护了空气敏感材料Zn,SiCl 4和Si在还原过程中不被氧化。 所得到的含有ZnCl 2的熔融盐可用于电解ZnCl 2以再生Zn金属。 电解过程中产生的氯可用于生产SiCl4。

    • In a method of performing a chemical reaction using a Lewis acid, after the reaction is complete, the Lewis acid is extracted from the reaction product in the form of an aqueous solution, followed by drying of the aqueous solution of the Lewis acid. The dried Lewis acid can be reused in a further similar reaction. The method can be repeated several times, using the same batch of Lewis acid, without the activity and specificity of the Lewis acid being significantly affected. The invention has been used to good effect in the ene reaction of isopulegol from citronellal, the Diels-Alder reaction of myrcene and 3-methyl-3-penten-2-one and the rearrangement reaction of alpha -pinene oxide to campholenic aldehyde using zinc bromide as a Lewis acid catalyst. The invention can thus provide an environmentally acceptable and efficient method for using Lewis acids in industrial processes.
