Abstract

The invention discloses an iron stearate preparation method. The method comprises the following steps: 1, taking sodium hydroxide to prepare an aqueous solution with the concentration of 2-5%, heating to 85-95DEG C, slowly adding stearic acid while stirring, and reacting under a pH value of 9-10 to obtain a sodium stearate solution; 2, cooling the sodium stearate solution to 50DEG C, adding a soluble iron salt solution preheated to 65DEG C and having a concentration of 10-15%, and adding a zinc oxide catalyst; and 3, filtering, washing with water, and drying to obtain iron stearate powder. The method has a high product yield, and enables products to have the advantages of water washing convenience, good purity and narrow melting point range.

Description

technical field [0001] The invention relates to a method for preparing iron stearate. Background technique [0002] Iron stearate is a plastic photosensitizer, which has the advantages of low toxicity, low cost, and obvious photosensitization effect, so it has been widely used in the research of degradable plastics. There are few reports on the physical and chemical properties and preparation methods of iron stearate. The synthesis of ferric stearate has two kinds of direct synthesis method and saponification-metathesis synthesis method, and shortcoming is that productive rate and yield are all low. Contents of the invention [0003] The technical problem to be solved by the present invention is: provide a kind of iron stearate preparation method. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: [0005] A kind of iron stearate preparation method, comprises the following steps: [0...
