摘要:
为研究聚乙二醇6000（PEG6000）合成工艺的热危险性，将PEG6000的合成过程分为8个阶段，采用反应量热仪（RC1e）和绝热加速量热仪（ARC）对8个阶段的放热情况及不同阶段PEG产品的稳定性进行测试，并将绝热升温Δθad与θD8相关联，提出了危害可控点的计算方法。RC1e结果表明:PEG127、PEG300、PEG806、PEG1500、PEG3350的失控严重度等级为4级；PEG4000的失控严重度等级为2级。ARC结果表明，θD8在311.32~318.39 ℃之间。危害可控点计算结果表明：PEG300的危害可控点数值最大,为69.43%；PEG4000危害可控点数值小于0。因此，在实际生产中，应格外重视PEG300这一合成阶段，可通过延长通气时间、减缓通气速率等措施避免体系温度升高过快而造成产物分解，降低反应过程的危险程度，实现企业的安全生产。
Abstract:
In order to study the thermal risk of polyethylene glycol 6000 (PEG6000) synthesis process, the synthesis process of PEG6000 was divided into eight stages. Reaction calorimeter (RC1e) and adiabatic acceleration calorimeter (ARC) were used to test the heat release and stability of PEG products in different stages. The adiabatic temperature rise △θad?was correlated with θD8, and the calculation method of hazard controllable point was proposed. RC1e results show that the out of control severity levels of PEG127, PEG 300, PEG 806, PEG 1500 and PEG 3350 are Grade 4, and that of PEG4000 is Grade 2. ARC results show that the θD8?of PEG products is 311.32-318.39 ℃. Results of hazard controllable point calculation show that the hazard controllable point of PEG300 is the largest (69.43%), and that of PEG4000 is less than 0. Therefore, special attention should be paid to the synthesis stage of PEG300 in actual production. Measures such as prolonging the ventilation time and slowing down the ventilation rate can avoid the decomposition of products caused by the rapid rise of system temperature, to reduce the risk of reaction process and to realize the safety production of enterprises.
