Biodiesel Production Line Biology derv net on Feburary 3 dispatch: Dalian of Chinese Academy of Sciences changes content place to was in recently to benzene 2 second ester synthesizes 2 formic acid new headway is gained in the research of new line, should synthesize new line to stick health acid in order to give birth to corporeal radical to be raw material, but not classics is right xylene (PX) synthesize pair of benzene directly 2 formic acid pair of benzene such as 2 second ester 2 formic acid (PTA) derivative. This research is used to optimize in laying corporeal radical raw material already some composition and special structure, the compound of high additional cost provided preparation likelihood. Our country PTA was produced 2014 can be in 46 million tons of above. Current, PTA of the production on industry basically passes pair of oil radical to be made to xylene oxidation.
