乙炔在氯丁橡胶生产中是合成乙烯基乙炔的原料,在乙炔的制纯和乙炔合成乙烯基乙炔后的制纯过程中,均有部分乙炔进入废水中。乙炔(C_2H_2)是无色的可燃性气体,分子量为26.04。一升乙炔气体在0℃及760毫米汞柱下重1.173克。其在水中的溶解度:水温为10℃时,每升水为1.31升,20℃时为1.03升,25℃时为0.93升。 Acetylene is a raw material for the synthesis of vinyl acetylene in the production of chloroprene rubber. During the pure process of making acetylene and acetylene after acetylene synthesis, part of acetylene enters the wastewater. Acetylene (C 2 H 2) is a colorless, flammable gas with a molecular weight of 26.04. One liter of acetylene gas weighed 1.173 grams at 0 ° C and 760 mmHg. Its solubility in water: at a water temperature of 10 ° C, 1.31 liters per liter of water, 1.03 liters at 20 ° C, and 0.93 liters at 25 ° C.
