Mawu Oyamba

Phthalate (yomwe imadziwikanso kuti ortho-dimethoxybenzene, kapena ODM mwachidule) ndi madzi opanda mtundu. Zotsatirazi ndikuwulula za chilengedwe, kugwiritsa ntchito, njira yopangira ndi chidziwitso chachitetezo cha ODM:

Imasinthasintha kwambiri kutentha kwa chipinda ndipo imatha kusungunuka mumitundu yosiyanasiyana ya organic solvents.

Kagwiritsidwe: ODM ili ndi ntchito zosiyanasiyana m'magawo ambiri. Angagwiritsidwenso ntchito kupanga utoto, mapulasitiki, utomoni wopangira, ndi mankhwala ena.

Njira yokonzekera: Kukonzekera kwa ODM kumatha kuchitidwa ndi phthalate etherification reaction. Pansi pa zochita za asidi chothandizira, phthalic acid imakumana ndi methanol kupanga methyl phthalate. Kenako, methyl phthalate imayendetsedwa ndi methanol yokhala ndi chothandizira cha alkali kupanga ODM.

Chidziwitso chachitetezo: ODM ili ndi kawopsedwe kena, ndipo chitetezo chikuyenera kuyang'aniridwa mukamagwiritsa ntchito ndikugwira ODM. Ndi madzi oyaka moto ndipo sayenera kukhudzana ndi magwero a moto. Pewaninso kupuma, kukhudzana ndi khungu ndi maso. Mukamagwiritsa ntchito ODM, muyenera kutsata njira zoyenera zodzitetezera monga kuvala magalasi oteteza ndi magolovesi, ndikuwonetsetsa kuti zikugwiritsidwa ntchito pamalo abwino mpweya wabwino.

Zam'mbuyo: Methyl p-tert-butylphenylacetate (CAS#3549-23-3)

Ena: Diethylsuccinate (CAS#123-25-1)
