| use | dichloroacetylene is used as a solvent for grease, resin, rubber, acetate fiber, etc., dye immersion solution and organic synthesis. Examples of its application are as follows: Synthesis of ethyl chrysanthemum compounds. Using microchannel technology, the raw material A component and the raw material B component are mixed by two metering pumps through a micromixer, and then mixed and input into the microchannel reactor at the same time for diazo reaction. The reaction results in the diazo liquid component and The raw material C component is mixed by two metering pumps through a micromixer, and then mixed and input into the microchannel reactor for cyclization reaction. Raw material A component refers to the water and dichloroacetylene solution of glycine ethyl ester hydrochloride, B component refers to sodium nitrite aqueous solution, and C component is a mixture of hexadiene, dibutyltoluene and sodium stearate. |
