- Preparation method of alkoxy benzamide
-
The invention relates to a novel preparation method of alkoxy benzamide. Specifically, the method comprises steps as follows: chlorobenzonitrile is taken as a raw material and subjected to a reaction with alkaline substances in the presence of a catalyst, alkoxy benzoyl cyanide is generated and subjected to a hydrolysis reaction, and alkoxy benzamide is generated. The method has the advantages that the raw material is cheap and available, reaction conditions are mild, and postprocessing is convenient and simple.

- Synthesis method of o-hexankyl oxybenzoamide serving as photosensitive material stabilizer
-
The invention relates to a synthesis method of o-hexankyl oxybenzoamide serving as a photosensitive material stabilizer. The synthesis process comprises the following steps: performing reaction on hexyldecanol serving as a raw material and benzene sulfonyl chloride under the action of an acid-binding agent to generate isohexadecyl sulfonate which does not need to be purified, and further performing substitution reaction on the isohexadecyl sulfonate and salicylamide under an alkaline condition, thus obtaining the o-hexankyl oxybenzoamide. According to the synthesis process, the influence of the acid-binding agent on the isohexadecyl sulfonate and the influence of alkali on salicylamide substitution reaction are investigated, and a process which is easy to operate, economical and practical is found.
