| 介绍了γ-丁内酯的典型制备方法及其在精细化学品制备中的应用，并通过对不同制备方法特点的分析，指出将顺酐催化氢化法和1，4-丁二醇或四氢呋喃催化脱氢法进行有效耦合是γ-丁内酯生产工艺的开发重点。根据不同外压下γ-丁内酯的沸点，通过Exponential Decay(Third order)非线性回归方法建立其沸点与外压的关联式:Tb=501.342 22-81.185 73e-2.139 36P -50.549 34e-0.181 50P -106.832 17e-0.014 638P，该方程的相关系数为R2=0.999 94，从而更好地实现了γ-丁内酯的产品质量控制。 |

| The typical synthetic method and application in the preparation of fine chemicals concerned with γ-butyrolactone were presented respectively, and the technological characteristics of different procedures were evaluated. The coupling of the catalytic hydrogenation of maleic anhydride and the catalytic dehydrogenation of 1, 4-butanediol and tetrahydrofuran, which was regarded as the research priorities for the preparation of γ-butyrolactone in future, was pointed out. According to boiling points of γ-butyrolactone at different external pressure, the equation for calculating the boiling point at given external pressure was constructed using Exponential Decay(Third order)non-linear regression: Tb=501. 342 22-81. 185 73e-2. 139 36P -50. 549 34e-0. 181 50P -106. 832 17e-0. 014 638P, and the correlation coefficient(R2)of equation was 0. 999 94. The product quality control of -butyrolactone was better achieved. |
