Lembe ango ma jutiyo kudu pi yubu maleic anhydride?

Yore mi yubu piny i ngom mawoko
Tic mi yubu piny ma kawoni Maleic Anhydride yore mi yubu piny utiye benzene-based, n-butane-based, C4 olefin-based, man phthalic anhydride byproduct-based.
Benzene ubedo piny macon ma jutiyo kudu pi maleic anhydride, ento benzene manok uketho juyubu yore mi C4 olefin man n-butane. Ngom ma ulony ku gas man oilfield (ma mio n-butane madwong) umedire pio pio tic pa n-butane—ma kawoni utiye ~80% pa kero mi yubu piny i ng'om zoo.

Pirango ma iyero Maleic Anhydride? Etiye thenge ma malu pa polyester resins ma unsaturated, man eyabu kemikol matung tung (BDO, THF, man mange). Cwal iwa waraga kawoni mi nwangu yore mi MA maber pi kuloka peri!
