Monkeypox is a zoonotic disease caused by monkeypox virus(MPXV).MPXV is a double-stranded DNA virus from the genus Orthopoxvirus that was firstly detected in captive monkeys in 1958[1],with first reported MPXV infected case in humans in the Democratic Republic of the Congo in *** zoonotic infection has since spread and become endemic in African countries,especially in West and Central Africa[2].Human monkeypox cases were detected outside Africa in 2003,however,recent cases have not been reported in non-endemic countries until 2022[3].

1,2-Disubstituted benzimidazoles are selectively synthesized in high yields under extremely mild conditions via the condensation of o-phenylenediamine derivatives with aldehyde derivatives using catalytic amount of iron（Ⅲ） phosphate under solventfree conditions. The use of readily available iron（Ⅲ） phosphate as a reusable and recyelable catalyst makes this process quite simple, convenient, and environment-friendly.

A finite volume model of a low pressure Ar-Hg electrodeless lamp with external coils is established. The physical configuration is similar to the OSRAM/ENDURA 70 W lamp. A Maxwellian energy distribution is assumed. Two dimensional behaviors of the most important plasma parameters such as the electron density, the electron temperature and the most important mercury states are discussed. Results are in good agreement with former studies and the general understanding in this area. Also, the influence of the argon pressure is studied. Based on the simulation, the population of the main resonance state, Hg （63p1） depends on the argon pressure and the optimized value is about 300 mTorr.
