The process of the current invention, named Percino-Chapela, has as one of its main novelty features that starting from pyridinmethanol derivatives, a dimerization or polymerization reaction of pyridinic alcohols is carried out in order to produce novel products, the process of the current invention has the following aspects that characterize it: it is carried out in the absence or presence of some solvent, during the process of the current invention, temperature may be or may be not used as catalyst, in the process of the current invention the reaction may be or may not be catalyzed by the presence of a catalyst (acid or base), the resultant products can be produced and separated in an easy way, in the process of the current invention starting from pyridinic alcohols the resultant ethenediols can be produced by a single step reaction, the pyridinmethanol derivatives used as starting compounds, do not oxidize as easily and their handling is easier than that of other compounds previously used that oxidize easily, the products produced with etheneidol parts can be used as antioxidants due to their capacity to act as free radicals scavengers.
本发明的过程名为Percino-Chapela,其主要的创新特点之一是从吡啶甲醇衍生物开始,进行吡啶醇的二聚或聚合反应,以产生新的产物。本发明的过程具有以下特点:可以在有或无溶剂的情况下进行,可以使用温度作为催化剂,反应可以或不能通过催化剂(酸或碱)进行催化,所得产物可以容易地生产和分离,从吡啶醇开始,可以通过单步反应产生所得的乙烯二醇,与先前容易氧化的其他化合物相比,作为起始化合物使用的吡啶甲醇衍生物不易氧化,其处理更容易,由乙烯二醇部分产生的产品可以用作抗氧化剂,因为它们具有作为自由基清除剂的能力。
