國內焦化苯為原料色熱穩定性不好是常見的，山東馬來酸酐在140度、2小時70#- 80#常見，嚴重200#左右(APHA)。以焦化苯為原料馬來酸酐的穩定劑尤其是它的優點，是SD公司引進的穩定劑無法比擬的。其效果是:在140攝氏度下，2小時鉑鈷小于20(通常是15#)。強化試驗在180攝氏度下1小時比較明顯(2小時在180攝氏度下，耐活條件下，一般不受馬來酸酐影響)”= 40 # . .加入，成本低:馬來酸酐0.3元/噸。化工廠添加穩定劑的馬來酸酐比不添加穩定劑的馬來酸酐高100-300元/噸，而且效果遠不如穩定劑。經濟效益明顯。加入馬來酸酐熱穩定劑可用于制造高檔樹脂，使產品質量穩定。要提高產品競爭力，直接提高經濟效益，ecru熱穩定劑的數量優于引進的效果。
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.
