Maleic Anhydride Hewalɛ ni Yaa Nɔ

IV. Maleik Anhaidaid Nɔyaa Nibii ni Yaa Nɔ
Yɛ China lɛ, benzene niyenii babaoo yɛ ni mlai ni akɛhaa lɛ baanyɛ atsake, kɛ shia ŋaalee kɛha benzene oksideshin ni tsiimɔ ji tɔn 10,000-ni damɔ shi Maleik anhaidraid feemɔ lɛ eda. No hewɔ lɛ, gbɛtsɔɔmɔi ni kɔɔ hiɛyaa he nyɛsɛɛ nɛɛ ji nɔ ni nyiɛ sɛɛ nɛɛ:
Yɛ gbɛ kome nɔ lɛ, okɛ ojwɛŋmɔ ama benzene oxidation gbɛjianɔtoo lɛ nɔ koni ekɛba nibii ni akɛtsuɔ nii kɛ mujiwoo shi, ni no aha akaŋshii aya hiɛ.
Yɛ gbɛ kroko nɔ lɛ, ha R&D mɔdɛŋbɔɔ aya hiɛ kɛha nibii ni jɛɔ maleic anhydride mli baa lɛ. Akɛ nɔkwɛmɔnɔ lɛ, nibii tamɔ polybutylene terephthalate (PBT) (ni ji 1,4-butanediol, BDO) kɛ polytetramethylene ether glycol (PTMEG) (ni ji tetrahydrofuran, THF) ni ataoɔ lɛ miiya hiɛ oya. Maŋ lɛ mli jarayeli lɛ yɛ nibii ni akɛhaa lɛ mligbalamɔ babaoo, ni nibii nɛɛ damɔ nibii ni akɛbaajɛ maŋsɛɛ aba lɛ anɔ titri.

Mɛni hewɔ esa akɛ ahala Maleic Anhydride lɛ? E ji hɛ mi nyami nɛ ji polyester resins nɛ a be hɛ mi nyami ɔ a se, nɛ e bliɔ tsopa slɔɔtoslɔɔtohi nɛ a ngɛ sisi ɔ mi (BDO, THF, kɛ ekrokomɛhi). Shɛɛ sane wɔ bianɛ koni wɔtao MA tsabaai ni ato he gbɛjianɔ kɛha onitsumɔ lɛ!
