Ni iyihe miterere y’umubiri n’imiti ya anhidride ya maleiki?

Ingano y'ibinyabutabire bya Maleic Anhydride: Mu bushyuhe bw'icyumba, igaragara nk'uduce tw'umweru, urushinge, uduce duto, inkoni, uduce duto cyangwa uduce duto, hamwe n'ubushyuhe bukomeye. Ubucucike: 1.48; Aho ishonga: 52.8°C; Aho ishyuha: 202.2°C. Maleic Anhydride ishobora kandi kuzamuka mu bushyuhe buri hasi (60-80°C). Irashonga muri ethanol, ether na acetone; ihura n'amazi ikarema aside maleic. Irashya, kandi umwuka wayo n'umukungugu bishobora gukora uruvange ruturika iyo bivanze n'umwuka.
Amabwiriza agenga imitungo (GB-3676-92)
Isura: Uduce tw'umweru, tuburungushuye
Ubuziranenge bwa Maleic Anhydride ≥99.5%
Aho kristali igera ≥52.4°C
Ibara rishonga ≤25Pt-Co
Ivu ririmo ≤0.005%
Ingano y'icyuma ≤5ppm

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!
