国内焦化苯为原料色热稳定性不好是常见的，山东马来酸酐在140度、2小时70#- 80#常见，严重200#左右(APHA)。以焦化苯为原料生产马来酸酐的稳定剂尤其是它的优点，是SD公司引进的稳定剂无法比拟的。其效果是:在140摄氏度下，2小时铂钴小于20(通常是15#)。强化试验在180摄氏度下1小时比较明显(2小时在180摄氏度下，耐活条件下，一般不受马来酸酐影响)”= 40 # . .加入，成本低:马来酸酐0.3元/吨。化工厂添加稳定剂的马来酸酐比不添加稳定剂的马来酸酐高100-300元/吨，而且效果远不如稳定剂。经济效益明显。加入马来酸酐热稳定剂可用于制造高档树脂，使产品质量稳定。要提高产品竞争力，直接提高经济效益，ecru热稳定剂的数量优于引进的效果。
It is common that coking benzene is used as raw material with poor color thermal stability in China. Maleic anhydride in Shandong Province is common at 140 ° C and 70 - 80 ° C in 2 hours, with a severity of about 200 ° C (APhA). The stabilizer for maleic anhydride production from coking benzene, especially its advantages, is incomparable to the stabilizer introduced by SD Company. The effect is that platinum cobalt is less than 20 (usually 15 × 3) in 2 hours at 140 ℃. The strengthening test is more obvious at 180 ℃ for 1 hour (2 hours at 180 ℃, under the living condition, generally not affected by maleic anhydride) "= 40 ?. The cost is low: 0.3 yuan / ton maleic anhydride. The price of maleic anhydride with stabilizer in chemical plant is 100-300 yuan / ton higher than that without stabilizer, and the effect is far worse than that of stabilizer. The economic benefits are obvious. The addition of maleic anhydride heat stabilizer can be used to manufacture high-grade resin and stabilize the product quality. The quantity of ecru heat stabilizer is better than that of imported heat stabilizer in order to improve the competitiveness of products and directly improve the economic benefits.
