1785-61-1 - Overview

isophthalenediacetylene has very important uses in pharmaceutical synthesis, liquid crystal materials, aerospace materials, etc.; the industrial production of high-purity isophthalenediacetylene is very difficult, and there are methods to use m-dibromobenzene as raw material, and 2-Methyl-2-hydroxybutyne undergoes hack reaction under the left and right of palladium catalyst, and then hydrolyzes to obtain isophthalenediacetylene. This method, the catalyst cannot be recovered and the industrialization cost is high. There are reports in the literature that mixed divinylbenzene is used as raw material, and the mixed diethynyl benzene is eliminated after bromination, and then separated; this method is difficult to obtain high-purity isophthalene diacetylene, and it is difficult to meet the purity requirements.
