A 77.5% of reduction in deposit formation could be obtained when the multiplex additive of tetralin/ tetralone binary donor and diphenyl diselenide was added into n-dodecane.
复合添加剂比单一试剂效果更明显,元供氢剂与苯的复合添加剂可减少77.5%的裂解沉积。
Through IR analysis, the main component in group II was identified as dialkyl-benzene, while in Group III was monoalkyl-benzene as well as dialkyl-tetralin and indane (DTI).
