摘要
用精密转动弹热量计测定了L-色氨酸、L-白氨酸、L-异白氨酸和L-丙氨酸的燃烧能,计算出它们的标准燃烧焓ΔcHθm分别依次为(-5575.83±3.99),(-3558.81±4.81),(-3569.32±8.33),(-1595.36±1.42)kJ/mol和标准生成焓ΔfHθm分别依次为(-467.76±4.25),(-660.14±4.88),(-649.64±8.37),(-585.58±1.48)kJ/mol。认为此结果比文献值更可靠。
Combustion energies have been determined for 4 amino acids (Lalanine,Lleucine,Lisoleucine,Ltryptophane) by using a rotatingbomb calorimeter.The corresponding standard enthalpies of combustion,ΔcHθm,(-5575.83±3.99),(-3558.81±4.81),(-3569.32±8.33),(-1595.36±1.42) kJ/mol,respectively, and the standard enthalpies of formation,ΔfHθm,(-467.76±4.25),(-660.14±4.88),(-649.64±8.37),(-585.58±1.48) kJ/mol,respectively,have been calculated.The results are more reliable than those of referenced.
