Taw qhia
Phthalate (tseem hu ua ortho-dimethoxybenzene, lossis ODM luv luv) yog cov kua tsis muaj xim. Cov hauv qab no yog kev qhia txog qhov xwm txheej, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb ntawm ODM:
Nws yog volatile heev nyob rau hauv chav tsev kub thiab yuav yaj nyob rau hauv ntau yam organic solvents.
Kev Siv: ODM muaj ntau yam kev siv hauv ntau qhov chaw. Nws kuj tseem siv tau los ua dyes, plastics, hluavtaws resins, thiab lwm yam tshuaj.
Txoj kev npaj: Kev npaj ntawm ODM tuaj yeem ua los ntawm phthalate etherification cov tshuaj tiv thaiv. Nyob rau hauv qhov kev txiav txim ntawm cov kua qaub catalyst, phthalic acid reacts nrog methanol los tsim methyl phthalate. Tom qab ntawd, methyl phthalate yog reacted nrog methanol nrog alkali catalyst los tsim ODM.
Cov ntaub ntawv kev nyab xeeb: ODM muaj qee yam toxicity, thiab kev nyab xeeb yuav tsum tau them sai sai rau thaum siv thiab tuav ODM. Nws yog cov kua ua kua thiab yuav tsum tau zam los ntawm kev sib cuag nrog hluav taws. Tsis tas li ntawd zam kev nqus pa, tiv nrog daim tawv nqaij thiab qhov muag. Thaum siv ODM, kev tiv thaiv tus kheej tsim nyog xws li hnav tsom iav thiab hnab looj tes yuav tsum tau siv, thiab xyuas kom meej tias nws siv nyob rau hauv qhov chaw muaj cua zoo.
