The present invention relates to a particulate magnesium ethoxide having a coarse particle content, to a process for its preparation and to its use.
During these long reaction times, the magnesium ethoxide particles formed as a rule disintegrate into a fine powder. At best spherical particles having very small diameters, for example 21.9 .mu.m, can be produced (JP-A-03074341). In order to increase the rate of reaction and to be able to prepare a product with larger particles, for example larger than 500 .mu.m, the reaction can be carried out in pure alcohol in an autoclave under elevated pressure and therefore at as elevated a temperature as possible (EP-A-997 451). This synthesis variant has the disadvantage that specific, expensive apparatuses are required. Furthermore, the magnesium ethoxide particles formed are saturated with excess alcoholate.More magnesium ethoxide information here.
