英文摘要	The synthesis of phenyl isocyanate (pi). was studied by thermal decomposition of methyl n-penyl carbamate (mpc) over tin catalysts. it has been found that di-n-butyltin oxide had higher activity. the unknown byproduct was determined as diphenylcarbodiimide (dpcd) by hplc-ms. the results show that the formation of n,n'-diphenylurea (dpu) and dpcd are the main competitive reactions to the synthesis of pi. at normal pressure, the conversion of mpc is 85.17% and the yield of pi is 67.65% over bu2sno under the optimal reaction condition, which is as follows: solvent, o-dichlorobenzene (odcb); m(odcb)/m(mpc) = 15; n(bu2sno)/n(mpc) = 0.075; reaction time, 1 h.
