Benzyl phenyl ether (BPE) was reacted to discuss the yields of decomposed products using solvents having various values of carbon aromaticities (fa) prepared from 2-rings compounds (decalin, tetralin and naphthalene) and a synthetic pyrite as catalyst. The reactions were carried out in a 50 ml autoclave at 673 K to 743 K of the reaction temperature under 3 Mpa of initial hydrogen or nitrogen pressure for 30 min.The conversions in all reactions were 100 wt% based on BPE. In the reaction using decalin as solvent, the decomposed products consisted of toluene, phenol and benzene were the most abundant constituent, In the reaction using tetralin or naphthalene as solvent, the decomposed products yield decreased because that benzyl radical produced from BPE by thermal cracking reacts with solvent to produce benzyltetralin or benzylnaphthalene. In the feactions using solvents having equal fa-value prepared by mixing decalin and tetralin, or decalin and naphthalene, the decomposed products yields were not so much different. However the decomposed product yields in the reaction using the mixed solvent of decalin and naphthalene was somewhat higher than that using the mixed solvent of decalin and tetralin.It is suggested that in the reaction using a mixed solvent having particular fa value, the decomposed product yields would increase.In future work the variations of solvents before and after reaction should be studied in detail to clarify hydrogen transfer from solvent to products.

以二环化合物（十氢萘、四氢萘和萘）和人工合成的黄铁矿为催化剂，制备了不同碳芳香度（fa）的溶剂，研究了苄基苯基醚（BPE）的分解产物产率。反应在50 ml高压釜中在673 K至743 K的反应温度下在3 Mpa的初始氢气或氮气压力下进行30 min。所有反应中的转化率基于BPE为100 wt%。在以十氢萘为溶剂的反应中，以甲苯、苯酚和苯为主要组分的分解产物，在以四氢萘或萘为溶剂的反应中，由于BPE热裂解产生的苄基自由基与溶剂反应生成苄基四氢萘或苄基萘，导致分解产物产率降低。在用十氢萘与四氢萘或十氢萘与萘混合而成的具有相同fa值的溶剂进行的反应中，其分解产物产率差别不大。但十氢萘和萘的混合溶剂反应的分解产物产率略高于十氢萘和四氢萘的混合溶剂反应的分解产物产率，这表明在使用具有特定fa值的混合溶剂的反应中，在今后的工作中，应详细研究反应前后溶剂的变化，以阐明氢从溶剂到催化剂的转移过程。产品.
