Iindlela zoPhuhliso lweMaleic Anhydride
IV. I-Maleic Anhydride Iindlela zoPhuhliso
E-China, i-benzene feedstock ininzi kwaye inolawulo oluguquguqukayo lokubonelela, kwaye ubuchwepheshe basekhaya bokuvelisa i-benzene oxidation-based maleic anhydride eyi-10,000-tons buvuthiwe. Ke ngoko, imiyalelo yophuhliso lwakutshanje yile ilandelayo:
Kwelinye icala, gxila ekwenzeni ngcono nasekuphuculeni inkqubo ye-benzene oxidation ukunciphisa ukusetyenziswa kunye nongcoliseko, ngaloo ndlela kuphucula ukukhuphisana.
Kwelinye icala, yandisa imizamo yophando nophuhliso kwiimveliso ezisezantsi ze-anhydride ye-maleic. Umzekelo, imfuno yeemveliso ezifana ne-polybutylene terephthalate (PBT) (imveliso esezantsi ye-1,4-butanediol, BDO) kunye ne-polytetramethylene ether glycol (PTMEG) (imveliso esezantsi ye-tetrahydrofuran, THF) ikhula ngokukhawuleza. Imarike yasekhaya inomsantsa omkhulu wokubonelela, kwaye ezi mveliso zixhomekeke kakhulu ekuthengisweni kwamanye amazwe.
