The boiling range is 120 ~ 200 ℃, mainly composed of toluene, xylene isomer Chemicalbook, ethylbenzene, cumene, etc. The relative density is (20℃/4℃) 0.85～0.95, the flash point is 35～38℃, and the chemical properties are similar to toluene and xylene.

개요Naphtha (petroleum), light alkylate is a light petroleum product, the word comes from Persian, which refers to volatile petroleum products, generally refers to the fraction of 30 ~ 220 ℃. Since the 1960s, with the development of the petrochemical industry, naphtha has become an important raw material for the production of ethylene, propylene, benzene, toluene and xylene by tube furnace cracking.
