Abstract: 57 Improved methods for preparing metal alkoxides from metals and alcohols involve dry-grinding the metal in an inert atmosphere prior to the addition of the alcohol. When an activator is used, it is usually ballmilled with the metal. Higher yields are obtained particularly when the metal and alcohol are not very reactive without an activator. Typical metals are those from Groups 2A, 2B, 3A, and 3B, particularly aluminum, magnesium, and yttrium. Typical alcohols are those which contain up to 16 carbon atoms, particularly those containing 4 or more carbon atoms.
Abstract translation: 从金属和醇制备金属醇盐的改进方法包括在加入醇之前在惰性气氛中干磨金属。 当使用活化剂时，通常用金属球磨。 特别是当金属和醇在没有活化剂的情况下不是非常活泼的情况下获得更高的收率。 典型的金属是来自2A，2B，3A和3B族的金属，特别是铝，镁和钇。 典型的醇是含有至多16个碳原子的醇，特别是含有4个或更多个碳原子的醇。

Abstract: A process for preparing an effective support for the titanium halide component of a coordinate complex catalyst for the polymerization of alphaolefins comprises the steps of:
a) intimately contacting a magnesium or manganese chloride or bromide with a drying agent at an elevated temperature, b) milling the magnesium or manganese chloride or bromide so as to activate its surface; and c) repeat contacting step a) and milling step b) for two or more cycles, whereby the effective support is produced.-
