| Abstract: | According to the characteristics and hazards of higher alkynes in butadiene device, the effect of temperature on explosion limit of vinyl acetylene was studied and determined through the measuring instrument of explosion limit and detonation tube. The safety partial pressure of vinyl acetylene under different temperature was determined, then the influence of nitrogen dilution on the safety partial pressure of vinyl acetylene was determined, and the characteristics of combustion, explosion and decomposition were obtained. It showed that vinyl acetylene is easily to occur out of control in decomposition or gas phase combustion and explosion, and the consequence is serious when happening occur out of control in decomposition. In order to ensure the safe use of vinyl acetylene in butadiene device, it is recommend to use vinyl acetylene at low temperature and low pressure. |
