Emitendera gy’enkulaakulana ya Maleic Anhydride
IV. Ekirungo kya Maleic Anhydride Emitendera gy’enkulaakulana
Mu China, emmere ya benzene nnyingi nnyo nga zirina amateeka agakyukakyuka mu kugaba, ne tekinologiya w’awaka ow’omutindo gwa ttani 10,000 benzene-based benzene oxidation-based Okukola ekirungo kya maleic anhydride akuze. Bwe kityo, endagiriro z’enkulaakulana ezisembyeyo ze zino wammanga:
Ku ludda olumu, essira lisse ku kulongoosa n’okulongoosa enkola ya benzene oxidation okukendeeza ku nkozesa n’obucaafu, bwe kityo n’okutumbula okuvuganya.
Ku luuyi olulala, okwongera ku kaweefube wa R&D ku biva wansi wa maleic anhydride. Okugeza, obwetaavu bw’ebintu nga polybutylene terephthalate (PBT) (ekintu ekiva wansi mu mugga ekya 1,4-butanediol, BDO) ne polytetramethylene ether glycol (PTMEG) (ekintu ekiva wansi mu mugga ekya tetrahydrofuran, THF) bweyongera mangu. Akatale k’omunda mu ggwanga kalina ekituli kinene mu by’amaguzi, era ebintu bino okusinga byesigamye ku bintu ebiyingizibwa mu ggwanga.
