应用Hildebrand参数法计算C_3、C_4炔、烯烃的溶解度及其选择性考查

With the Melhod of Hilderand Parameter Counts Solubilities And Examines Selectivities of the Alkyne(C_3、C_4)And Alkylene

本文在简要介绍溶解度参数(Hildebrand参数)的基础上应用Hildebrand参数及其相关经验公式,计算了乙炔(A—C_2H_2),甲基乙炔(M—C_3H_4),丙二烯(P—C_3H_4),乙烯基乙炔(V—C_4H_4),在二甲苯(Xylene)中的溶解度,并将乙炔的溶解度同后三者进行了比较,其比值定义为选择性。讨论了用选择性作判据,判断能否用二甲苯作为分离浓乙炔中C_3、C_4炔,烯烃的吸收溶剂。以上四种气体在二甲苯中的溶解度,本文还提供了两种不同测定方法的实测值。

After briefly introduced Hildebrand Parameter of solubility, it counts thesolubilities of acetylene(A-C_2H_2), methylacetylene (M-C_3H_4), propadiene(P-C_3H_4), vinylacetyene(V-C_4H_4)in the xylene with the Hildebrand Paramete and empiric formula of velative, Take a comparison of solubility between acetyleneand other alkyne (C_3、C_4) or alkylene(C_3、C_4) and names the specific value asselectivity.It also discusses the possibility of xylene as absorbent in separatingthe alkyue(C_3、C_4) and alkylene(C_3、C_4) from the thick acetyleneg. Lastly, thetext provides data of solubility from two different method to test the four ykindsgases in the xylene.
