Method for quickly synthesizing ferric stearate

Abstract

The invention discloses a method for quickly synthesizing ferric stearate, which comprises the following steps of: directly adopting stearic acid, ferric oxide and ferric trioxide as raw materials; adding a catalyst; and then reacting at 70 DEG C for 2 hours to obtain a ferric stearate mixture. The method disclosed by the invention has the advantages of no alkali liquor addition, little production waste liquor, simple process, low energy consumption and high ferric stearate purity.

Description

technical field [0001] The invention belongs to the technical field of organic compound synthesis, in particular to a method for rapidly synthesizing iron stearate. Background technique [0002] Iron stearate can be used as plastic photosensitizer, and its synthetic method mainly adopts saponification-metathesis method, and this method needs to add a large amount of lye, thereby generates a large amount of salt waste liquid, and iron stearate in reaction process It is easy to float on the liquid surface, affecting the progress of the reaction, resulting in low product yield and poor quality. Contents of the invention [0003] For solving above technical problem, the object of the present invention is to provide a kind of method of fast synthetic iron stearate. [0004] The method of the present invention adopts the following technical scheme: stearic acid, ferric oxide and ferric oxide are mixed evenly in a mass ratio of 50:30:20, and after adding a catalyst, they are rea...
