Experimental Section Materials and Analysis The chemicals used for the kinetic study were of analytical grade (rectapur); Amberlyst 15 and concentrated sulphuric acid were selected as catalysts. For the reactive distillation experiments, the chemicals were of reaction grade (99.5%) and sulphuric acid was the catalyst. All samples were analysed by gas chromatography (Varian 3800) using cross-linked polyethylene glycol CP-WAX 52 CB 30 m 0.32 mm column with FID detector. For the homogeneously catalyzed kinetic runs, the acetic acid concentration has been determined using titration; additional titrations were performed with a METTLER DL 35 Karl–Fischer-Titrator to measure the quantity of water formed during the reaction. A data reconciliation process was led in order to appreciably increase reliability and consistency of results: the elimination of aberrant measurements is performed on the base of the atomic conservation (Fillon et al., 1995). An accuracy of molar fractions of 3% can thus be expected. |

Experimental Section Materials and Analysis 实验部分:材料和分析方法 The chemicals used for the kinetic study were of analytical grade (rectapur); Amberlyst 15 and concentrated sulphuric acid were selected as catalysts.动力学研究所用试剂均为分析纯;选用大孔树脂15和浓硫酸为催化剂。 For the reactive distillation experiments, the chemicals were of reaction grade (99.5%) and sulphuric acid was the catalyst. 在蒸馏反应实验中,所用试剂为反应级(99.5%),催化剂为硫酸。All samples were analysed by gas chromatography (Varian 3800) using cross-linked polyethylene glycol CP-WAX 52 CB 30 m 0.32 mm column with FID detector. 全部样品以气相色谱(瓦里安3800)进行分析:交联聚乙二醇CP-WAX 52 CB 30 m 0.32 mm 分析柱;氢火焰离子化检测器。For the homogeneously catalyzed kinetic runs, the acetic acid concentration has been determined using titration; additional titrations were performed with a METTLER DL 35 Karl–Fischer-Titrator to measure the quantity of water formed during the reaction.均相催化动力学分析中,乙酸浓度通过滴定确定;反应期间生成水的量通过梅特勒DL 35卡尔-费舍尔滴定仪测定。 A data reconciliation process was led in order to appreciably increase reliability and consistency of results: the elimination of aberrant measurements is performed on the base of the atomic conservation (Fillon et al., 1995). An accuracy of molar fractions of 3% can thus be expected.数据加以核对以提高结果的可靠性和一致性:在原子守恒的基础上剔除了部分偏畸数据(Fillon et al., 1995)。预期准确度为摩尔分数3%。 |
