摘要：NOVELTY - Production of 1,3-diacetylene benzene is carried out by using 1, 3-dihalogenated benzene as raw material, Hack reacting with 2-methyl-2-hydroxy-butyne-2, obtaining intermediate 1,3-bis-2,-methyl-2-hydroxy-butyne-2-dibasic benzene, and deacetonizing to obtain 1,3-diacetylene benzene. It achieves low cost, simple operation and high purity.
