NON-ISOTHERMAL KINETICS OF THERMAL DECOMPOSITION OF A NOVEL ANTITUMOR AGENT 4-{5-[3,4-DIMETHYL-5-(3,4,5-TRIMETHOXYPHENYL)THIOPHEN-2-YL]-2-METHOXYPHENYL}MORPHOLINE

The thermal decomposition of a new antitumor agent,4-{5-[3,4-dimethyl-5-(3,4,5-trimethoxyphenyl)thiophen-2-yl]-2-methoxyphenyl}morpholine was studied by Differential Scanning Calorimetry(DSC)and Thermogravimetry(TG)/Derivative Thermogravimetry(DTG)methods at a flow rate of nitrogen gas of 120 mL/min,The kinetic parameters were obtained from the analysis of the corresponding curves by Kissinger's method,Ozawa's method and the integral method,The results indicate that the apparent activation energy and pre-exponential constants of the decomposition reaction are 106.67 kJ/mol and 10^6.19s^(-1),respectively.

平急一体化下生活物资虚拟众储快速响应机制研究

为实现生活物资的精准储备与及时供应,受分区智能化仓储与智能物联思想的影响,考虑到灾害的复杂性、不确定性与动态性,针对国家对生活物资配置的需求,在生活物资“平急一体化”协同适配机制研究的基础上,构建“平时为辅,急时为主”的虚拟物资大众储备保障机制,借助大数据手段,保证物资合理分配的同时,提高分配效率。区别于传统储备仓的建立方式,该模式以“预防为主”,将“平”与“急”相结合,有利于实现储存资源的均衡性、多样性、合理性,减少储存资源的浪费,节约储存成本,推动平急一体化协同储备,为应急生活物资的及时供应助力。
