Bv\常用物质的表面张力SurfaceTensionsofCommonSubstances下面两表中无机物和有机物的表面张力均为液态时的表面张力。液体的表面张力γ，单位为dyn/cm，1dyn/cm=1mN/m。对大多数化合物来说表面张力依赖于温度的变化，可表示为γ=a–bt这里a,b是常数，t是温度（℃）。a,b的值由表给出。常见无机物的表面张力SurfaceTensionsofCommonMinerals分子式(Molecularformula)表面张力(Surfacetension)分子式(Molecularformula)表面张力(Surfacetension)a/(dyn/cm)b/[dyn/(cm·℃)]a/(dyn/cm)b/[dyn/(cm·℃)]Ar34.280.2493N226.420.2265AsBr354.510.1043NO-67.480.5853AsCl341.670.0978N2O5.090.2032BBr331.900.1280NOCl29.490.1493BF3-2.920.2030NOF14.000.1165B2H6-3.130.1785NO2F8.260.1854Br245.50.1820O2-33.720.2561BrF338.300.0999PBr345.340.1283BrF525.240.1098PCl331.140.1266ClF326.90.1660PI361.660.06771ClO3F12.240.1576POCl335.220.1275CO-30.200.2073PSCl337.000.1272COCl222.590.1456S2Cl2（二聚物）46.230.1464COS12.120.1779SF412.870.1734DH6.5370.1883SF5.660.1190F2-16.100.1646SO226.580.1948GaCl335.00.1000SOCl236.100.1416HBr13.100.2079SO2Cl232.100.1328HF10.410.07867SbCl347.870.1238H2O278.970.1549SbF549.070.1937H2S48.950.1758SeF438.610.1274H2Se22.320.1482SiCl420.780.09962H2Te29.030.2619SiHCl320.430.1076Hg490.60.2049SnCl429.920.1134IF533.160.1318UF625.50.1240Kr40.5760.2890---常见有机化合物的表面张力SurfaceTensionsofCommonOrganicSubstances名称(Name)表面张力(Surfacetension)名称(Name)表面张力(Surfacetension)a/(dyn/cm)b/[dyn/(cm·℃)]a/(dyn/cm)b/[dyn/(cm·℃)]1,2-乙二胺44.770.1398顺-4-甲基环己醇29.070.06901,2-乙二醇50.210.0890甲基环戊烷24.630.1163乙苯31.480.10942-甲基吡啶36.110.12432-乙氧基乙醇30.590.0897邻甲酚39.430.1011乙氧基苯35.170.1104间甲酚38.000.09237乙基环己烷27.780.1054对甲酚38.580.09622,2-(亚乙基二氧基)二乙醇47.330.0880甲酰胺59.130.0842乙腈29.580.1178甲酸39.870.1098乙酸乙酰甲酯34.980.0944甲酸甲酯28.290.1572乙酰乙酸乙酯34.420.1015甲酸乙酯26.470.1315乙酰胺47.660.1021甲酸丙酯26.770.1119乙酸29.580.0994甲酸丁酯27.080.1026乙酸甲酯27.950.1289甲醇24.000.0773乙酸乙酯26.290.1161丙二酸二乙酯33.910.1042乙酸丙酯26.600.11201,3-丙二醇47.430.0903乙酸异丙酯24.440.10722-丙炔-1-醇38.590.1270乙酸丁酯27.550.1068丙胺24.860.1243乙酸戊酯27.660.09943异丙胺19.910.09719乙酸异戊酯26.750.0989异丙基苯30.320.1054乙酸酐35.520.1436丙烯腈29.580.1178乙酸烯丙酯28.730.11862-丙烯-1-醇27.530.0902乙醇24.050.0832丙腈29.630.1153乙醛23.900.1360丙酮26.260.112二乙胺22.710.1143丙酸28.680.0993二乙醚18.920.0908丙酸甲酯27.580.1258二丁胺26.500.0952丙酸乙酯26.720.1168二丁基醚24.780.09341-丙醇25.260.0777邻二甲苯32.510.11012-丙醇22.900.0789间二甲苯31.230.11042,4-戊二酮33.280.1144对二甲苯30.690.1074戊烷18.250.11021二(2-甲氧基乙基)醚32.470.11641-戊烯18.200.1099二甲氧基甲烷23.590.1199顺-2-戊烯19.730.11721,2-二甲氧基苯34.40.0642反-2-戊烯18.900.099722,2-二甲基丁烷18.290.0990戊腈29.280.09372,3-二甲基丁烷19.380.099982-戊酮24.890.065472,3-二甲基丁醇26.220.09923-戊酮27.360.1047N,N-二甲基苯胺38.140.10491-戊酸28.900.0887二甲基胺29.500.12651-戊醇27.540.08742,3-二甲基戊烷19.940.095652-戊醇25.960.10042,4-二甲基戊烷20.090.09715四氢-2-呋喃甲醇39.960.1008二丙胺24.860.10221,2,3,4-四氢萘35.550.0954二异丙胺21.830.10771,1,2,2-四氯乙烷38.750.1268二丙基醚22.600.1047四氯化碳29.490.1224二异丙醚19.890.10481,1,2,2,-四溴乙烷52.370.1463二戊基醚26.660.0925肉桂酸乙酯39.990.1045二异戊醚24.760.0871辛烷23.520.09509二卞胺43.270.10861-辛烯23.680.09581二苯基醚35.170.1104辛腈29.610.08021,4-二氧六烷36.230.13911-辛醇29.090.07...
