Maleic Anhydride Nkɔso Nkɔso
IV. Maleic Anhydride a wɔde yɛ aduru Nkɔso a Ɛkɔ So
Wɔ China no, benzene aduan a wɔde ma no dɔɔso a ɛwɔ mmara a ɛyɛ mmerɛw a wɔde ma, ne ɔman no mu mfiridwuma a wɔde yɛ benzene a ɛyɛ tɔn 10,000 a egyina oxidation so Maleic anhydride a wɔyɛ no ho akokwaw. Enti, nkɔso ho akwankyerɛ a wɔde ama nnansa yi no te sɛ nea edidi so yi:
Ɔkwan biako so no, fa w’adwene si benzene oxidation nhyehyɛe no a wɔbɛma ayɛ papa na wɔayɛ no yiye so na ama wɔatew nneɛma a wɔde di dwuma ne efĩ so, na ɛnam so ama akansi no ayɛ kɛse.
Ɔkwan foforo so no, ma R&D mmɔdenbɔ a wɔbɔ wɔ nneɛma a ɛwɔ maleic anhydride a ɛwɔ nsu ase ho no nkɔ soro. Sɛ nhwɛso no, nneɛma te sɛ polybutylene terephthalate (PBT) (afiri a ɛwɔ fam a ɛyɛ 1,4-butanediol, BDO) ne polytetramethylene ether glycol (PTMEG) (aduru a ɛwɔ tetrahydrofuran, THF a ɛwɔ fam) a wɔhwehwɛ no renya nkɔanim ntɛmntɛm. Ɔman no mu gua no wɔ nsonsonoe kɛse wɔ nneɛma a wɔde ma mu, na saa nneɛma yi gyina nneɛma a wɔde fi amannɔne ba so titiriw.
