Maleic anhydride
The production method
Maleic anhydride was produced by catalytic oxidation of benzene to prepare, but due to the price reason, now mostly used in n-butane oxidation method: 2CH3CH2CH2CH3 + 7 O2 2 C2H2 (CO) 2O + 8H2 The reaction can occur
Hydrolysis of maleic acid (cis-HO2CCH=CHCO2H), 1:1 alcoholysis generates monoester； Dear cis-HO2CCH=CHCO2CH3,used as a dienophile Diels Alder reaction; Low metal ligand, complex examples such as Pt (PPh3) 2 (MA) and Fe (CO) 4 (MA).

Introduction Chemical English name Physical properties Chemical properties
Styrene
Introduction Styrene is a kind of aromatic hydrocarbons. The olecular formula is C8H8。Simple structure type is C6H5CH=CH2. It’s exist in the Styrax (a kind of natural spices). Chemical formula Scale model
Styrene
Chemical properties Styrene polymerization at room temperature can be slow。It can agent hydroquinone or tert butyl catechol poly (0.0002% ~ 0.002%) and resistance as a stabilizer to delay the polymerization. Styrene dimer formation of polystyrene resin, it can also with other unsaturated compounds copolymerization, generation of synthetic rubber and resin and other products. For example, styrene butadiene rubber is a copolymer of butadiene and styrene; raw material of ion exchange resin of styrene and a 1, 4- two (vinyl) benzene copolymer. Reaction of styrene can also occur in the unique and olefin.
