摘要

用气液色谱法测定了戊烯-1-炔-4(C_5~(?))与异戊二烯(IP)在N-甲基吡咯烷酮(NMP)、二甲基甲酰胺(DMF)和乙腈中的无限稀释下的相对挥发度.结果表明

NMP分离能力最好

DMF次之

乙腈最次

乙腈掺水后可改善分离能力.用鼓泡夹带平衡釜测定了下列体系在0、15、30℃左右的汽液平衡:(1)2-甲基丁烯-2-C_5~(?);(2)正戊烷-C_5~(?);(3)IP-C_5~(?);(4)C_5~(?)乙腈;(5)IP-C_5~(?)-乙腈;(6)IP-C_5~(?)-DMF;(7)IP-C_5~(?)-NMP.用回归出的二元Wilson参数推算体系(5)的三元汽液平衡与实测值比较

汽相组成的平均偏差为0.0114摩尔分数.

Abstract

The relative volatilities at infinite dilution in solvents N-methyl pyrroli-done (NMP)

N-dimethyl formamide (DMF) and acetonitrile for penten-1-yne-4 and isoprene were determined by gas chromatography. Results showed NMP and DMF to be better than acetonitrile for separating penten-l-yne-4 from isoprene. Vapor liquid equilibria for the following systems were determined at 0

30℃ by the use of a modified Junghans still and the Wilson parameters Δ for binay systems were evaluated by regression method. ( 1 ) 2-methyl-butene-2-penten-1-yne-4

(2) n-pentane-penten-1-yne-4

(3) isoprene-penten-1-yne-4

( 4 ) penten-1-yne-4-acetonitrile

( 5 ) isoprene-penten-1-yne-4-acetonitrile

( 6 ) isopene-penten-1-yne-4-DMF

(7 ) isoprene-penten-1-yne-4-NMP

The vapro-liquid equilibrium for the ternary system ( 5 ) was predicted by the use of Δ for binary systems. The mean deviation of vapor compositions was 0.0114 mole fraction as compared with experimental results.
