Ni iyihe nzira ya Phthalic Anhydride ikomoka ku bicuruzwa bya Maleic Anhydride?

Uburyo bwo gukora Anhydride ya Phthalic
Iyo hakozwe anhydride ya phtalike iva muri o-xylene, anhydride ya maleic iba ari umusaruro ukomoka kuri (~ 5% by'umusaruro wa anhydride ya phtalike). Mu gihe cyo gukora anhydride ya phtalike, umwuka woza inyuma y'umurizo urimo kugira ngo ukuremo ibintu bikomoka ku bimera; amazi yoza (arimo anhydride ya maleic, aside benzoic nke, na aside phtalike) arahuzwa, agasukurwa, kandi BYIZAbyakozwe kugira ngo bikureho amazi mu mubiri—bigatanga umusaruro wa anhidride y'abagabo.

Kuki wahitamo Maleic Anhydride? Ni inkingi y'amaresini ya polyester adafite ubushyuhe bwinshi, kandi ifunguye imiti itandukanye (BDO, THF, nibindi). Twoherereze ubutumwa ubu kugira ngo ushakishe ibisubizo bya MA byagenewe ubucuruzi bwawe!
