摘要:
为评价丁基钠黄药的热稳定性,采用真空安定性测试仪和C600量热仪对其热分解过程进行了研究。分别考察了质量为10g的样品在温度为60℃、70℃、80℃、90℃、100℃和质量为05g、075g、10g、125g、15g、175g、20g的样品在温度80℃条件下的热分解特性。结果表明,采用真空安定性测试仪在80℃、21mL真空封闭空间的测试条件下,当丁基钠黄药质量小于125g时,其平均分解速率较慢,与时间近似成线性关系;当样品质量大于150g时,其平均分解速率与时间近似呈一条S形曲线。平均分解速率与质量不是成正比,而是先增加后减小,质量为165g时,平均分解速率最大,为00957mL/(g·h)。采用C600量热仪确定了丁基钠黄药的分解过程为吸热反应,起始分解温度为93℃,分解过程吸收热量为11051J/g。明确了温度、堆积样品量的大小和时间为影响丁基钠黄药热稳定性的主要因素
Abstract:
The thermal stability of sodium nbutyl xanthate were studied by means of Calvet calorimeter C600 and vacuum stability tester. In this article, the thermal decomposition characteristics of 10g sample were investigated at the temperature of 60℃, 70℃, 80℃, 90℃, 100℃ and 05g, 075g, 10g, 125g, 15g, 175g, 20g sample at 80℃. The testing results of vacuum stability tester in testing conditions(80℃and 21mL vacuum space) show an approximately linear relationship between the sodium nbutyl xanthate decomposition and time. The average decomposition rate is slow when the mass of sodium nbutyl xanthate less than 125g. If the mass exceeds 15g, it is an approximately Ssharped curve. At the same time, the average decomposition rate of the sodium nbutyl xanthate is not proportional to the mass. It increases firstly and then decreases. When the mass is 165g, the maximum average decomposition rate is achieved, which is 00957 mL/(g·h). In the meantime, according to the results of Calvet calorimeter C600, the decomposition reaction of sodium nbutyl xanthate is an endothermic process, the initial decomposition temperature and enthalpy of which is 93℃ and 11051 J/g respectively. According to the study, it manifests clearly and definitely that temperature, size of accumulation mass and time are the main factors to affect the thermal stability of sodium nbutyl xanthate.
