| 5 | Heat of Boron Trifluoride–Methanol System Determined by Bunsen Ice Calorimeter显示文摘The complex heat of BF_3 with methanol was measured by utilizing the principle of the Bunsen ice calorimeter. The complex heat of BF_3 –methanol was found to be 49.2 and 58.1 kJ/mol when the molar ratio of BF_3 to methanol was 1:2 and 1:1,respectively. In addition,the complex heat of BF_3 –anisole was also measured to test the apparatus error. The BF_3 –anisole result showed a calorimeter value of 53.1 kJ/mol with a system error of 2.3% as compared with the value reported in the literature. The mechanism of the reaction of BF_3 and methanol was interpreted based on our obtained results. This apparatus is useful and suitable for measuring the heat of other liquid–gas and liquid–liquid reactions. | Weijiang Zhang Yace Zhang Yuvaraja Gutha Jiao Xu | 2018 | Transactions of Tianjin University2018，24，4： | 0 |
