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
The present invention relates to a kind of iron stearate preparation method.
Background technology
Iron stearate is a kind of plastics photosensitizer additive, has the advantages such as low toxicity, cheapness, photosensitization successful, thereby is used widely in degradative plastics research.About physico-chemical property and preparation method's bibliographical information of iron stearate little.Iron stearate synthetic has two kinds of direct synthesis technique and saponification-metathesis synthesis methods, and shortcoming is that productive rate and yield are all lower.
Summary of the invention
Technical problem to be solved by this invention is: a kind of iron stearate preparation method is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of iron stearate preparation method, comprises the following steps:
(1) get sodium hydroxide and be configured to the aqueous solution of concentration 2-5%, be heated to 85-95 degree Celsius, slowly add stearic acid under stirring, the pH of reaction is 9-10, obtains sodium stearate solution;
(2) sodium stearate solution is cooled to 50 degrees Celsius, add be wherein preheated to 65 degrees Celsius the concentration soluble iron salts solution that is 10-15%, and add Zinc oxide catalytic;
(3) washing after filtration,, the dry iron stearate powder that obtains.
The invention has the beneficial effects as follows: product yield is high, product washing is convenient, good product purity, and melting range is narrow.
