The results also show that subtituent position on the benzene ring has a great influence on the transfer volume. The trends of change of δ〓ΔΦ〓〓 for mand p-isometers with the composition of the mixed solvent are similar. However, the position and amplitude of the limit valve are different from each other. These are discussed according to the inductive effect and the resonance effect.

Third, most magnesium alcoholates are prepared by alcoholysis.The process is based on the exchange of alkoxide groups of a metal alcoholate in the presence of an alcohol other than the alcohol corresponding to the original alkoxide,i.e.on the alcoholysis of a metal alkoxide with a different alcohol. Primary alcoholates can be prepared by this process,such as magnesium di-n-propanolate,magnesium di-n-butanolate,magnesium di-isobutanolate.
该方法适用于较高沸点的伯醇的醇镁化合物,例如正丙醇镁、正丁醇镁、异丁醇镁等,但是用醇解法制备出的叔丁醇镁,其纯度只有80%,这是由于叔丁醇具有较大的空间位阻效应,阻碍了醇交换的进一步进行,并且叔丁醇沸点与甲醇相差不大,使得甲醇难以快速蒸出,只能得到一种混合醇盐产物。

The present study, from the cognitive perspective, takes into consideration the following three points: the cognition of apposition is based on the knowledge of types and categories of things and objects; the original expression and its appositional expression are used as two different expressions for the same thing or event seen from different perspectives; the essential relationship between the two is that, in spite of the identical feature in syntax, they refer to different aspects of the object described out of different considerations.
