Effect of reactant molarity and reaction temperature on the yield of 1,2-octanediol Jan 08, 2019

In the course of the synthesis reaction, theoretically, the molar ratio of formic acid, hydrogen peroxide and 1-octene is 1:1:1. In this reaction system, formic acid is involved in the chemical reaction to produce peroxyacid. The raw material is also the solvent of the reaction system. Since hydrogen peroxide is easily decomposed, in order to make the reaction favorable to the formation of 1,2-octanediol, and also to improve the product yield and stabilize the reaction system, formic acid, hydrogen peroxide and 1-octene The molar ratio should be greater than 1.


In actual production, the reaction molar ratio of formic acid, hydrogen peroxide and 1-octene is usually set to 12:4:1. At the same time, the reaction temperature also has a significant effect on the product yield. Under the action of the catalyst, formic acid, hydrogen peroxide and 1-octene start to react at room temperature.


In order to carry out the reaction in a direction favoring the formation of 1,2-octanediol, it is necessary to increase the reaction temperature. Based on a comprehensive analysis, in the production process, we generally control the reaction temperature between 35 and 40 degrees.www.china-zhufengchem.com
