  The present invention relates to a process for the di-O-alkylation of a 1,3-diol according to Formula I (I), said process comprising reacting said 1,3-diol with dioxane, an aliphatic or aromatic hydrocarbon solvent, an alkali metal hydroxide, and dimethyl sulphate, in order to obtain a 1,3-diether according to Formula II (II), wherein R1 and R2 are each independently a hydrogen atom or a hydrocarbyl group selected from alkyl, alkenyl, aryl, aralkyl, or alkylaryl groups, and one or more combinations thereof. The process according to the invention is an improved process for preparing 1,3-diether, such as 9,9-bis(methoxymethyl)fluorene, in a high yield and/or having a high purity. 9,9-bis(methoxymethyl)fluorene is a compound that is used as an electron donor for Ziegler-Natta catalysts.

  本发明涉及一种根据式I（I）进行1,3-二醇的二-O-烷基化的方法，所述方法包括将所述1,3-二醇与二噁烷、脂肪族或芳香烃溶剂、碱金属氢氧化物和硫酸二甲酯反应，以获得根据式II（II）的1,3-二醚，其中R1和R2分别独立地是氢原子或从烷基、烯基、芳基、芳基烷基或烷基芳基组中选择的烃基团，以及一个或多个组合。根据本发明的方法是一种改进的制备1,3-二醚的方法，例如9,9-双（甲氧甲基）芴，其产率高和/或纯度高。9,9-双（甲氧甲基）芴是一种用作Ziegler-Natta催化剂的电子给体的化合物。
