| Abstract: | In the present paper, the effects of the catalyst, temperture and the time for reaction on the productivity have been investigated for synthesizing the titled compound. Therefore The amount of the catalyst for use and the optimal temper ture and time are determined the post-processing simplified and the productivity of the sample reached to the reference valee. The synthesized sample was proved to be the titled compound by M.p., IR., Ms. and Us.The effect of this compound used as antiseptics for fruits, vegetables and juices, has been fouvd excellent. |
