RELATIONSHIP OF THE GAS PHASE STANDARD ENTHALPIES OF FORMATION OF CH_3(?)CH_2(?)_nX AND THE STRUCTURAL FACTOR n·(1±(1/4n))~2

本文研究了影响 CH_3-(-CH_2-)_nX(x=-H、-OH、-SH、-Cl、-Br)的气相标准生成焓的各种因素.提出了一个计算通式:Δ_fH_m^8[CH_3(?)CH_2(?)_nX,g]=A+B·n(1±1/(4n))~2.通过50个化合物的计算,与实验值完全吻合,并预示了60个化合物的气相标准生成焓.

Based on the effect of various factors on the gas phase standard enthalpies of CH_3(?)CH_2(?)_(?)X (X=H,OH,SH,Cl,Br,etc),the paper has put forward a calculating model: Δ_rH_m~θ[CH_3(?)CH_2(?)_(?)X,g]=A+B·n(1±(1/4n))~2 The calculating values were conform to experiments for fifty compounds.the relative coefficients γ≥0.9982.It was predicted the gas phase standard enthalpies of formation for sixty compounds.
