I-1.Isetshenziswa njenge-solvent yokukhiqiza i-methyl-ethyl ketone petoxide, izimbobo ze-anticorrosive ezivuthayo.
I-2.Isetshenziswa njenge-spistic of sciellulose acetate, okuphindayo komiyane kanye ne-solvent of polyfluorooroomyleeneene coating.
I-3.ikuphakathi kwe-diphacin ye-rodenticide, i-tetramine ne-chlorratone.
I-Plistic:I-DMP isetshenziselwa ukuthuthukisa ukuguquguquka, ukuqina kanye nokusebenza kwamapulasitiki, ikakhulukazi i-polyvinyl chloride (PVC) namanye ama-polymers.
Usongele: Ingasetshenziswa njenge-solvent ekusungulweni okuhlukahlukene, kufaka phakathi upende, ukumboza kanye nama-adhesives.
Izimonyo nemikhiqizo yokunakekelwa komuntu siqu:I-DMP kwesinye isikhathi isetshenziswa ekwakhiweni kwezimonyo, njengamakha namakha nezipikili izikhala, ukwenza ngcono ukuthungwa nokuqina.
Izidakamizwa:Ingasetshenziswa njenge-excipients ekukhiqizweni kwezidakamizwa ezithile.
Cwaninga:I-DMP futhi isetshenziswa futhi ezinhlobonhlobo zamakhemikhali kanye nocwaningo ngezilungiselelo zelebhu.
U-Dimethyl phthalate uwuketshezi olunamafutha olungenamibala, elimnandi kancane. Akubukeki nge-ethanol, ether, incibilika e-benzene, i-acetone namanye ama-solvents ezi-organic, ukungasebenzi emanzini namafutha amaminerali.
1. Gcina endaweni yokugcina epholile, eyomile, kude nomlilo, ilanga nemvula. Gwema umthelela onobudlova ngesikhathi sokuhamba.
2. I-Plistic ngekhono elinamandla lokuqothula. Kusetshenziswe njengesositiki se-nitrile ruble, i-vinyl resin, ifilimu ye-cellulose, i-varnish acetate film, e-cellophane, i-varnish ne-vynish ne-powder, njll. Ingasetshenziswa njenge-solvent yokulungiselela i-methyl ketone petoxide. Inezakhiwo ezinhle kakhulu zefilimu, ukunamathela kanye nokumelana kwamanzi, kanye nokuqina okuphezulu okushisayo, kepha kulula ukukwenza i-crystallizet emazingeni okushisa aphansi futhi inokushintsha okuphezulu. Ngakho-ke, kuvame ukusetshenziswa ngokuhlanganiswa namapulasitiki afana ne-diethel perthalate yepulasitiki yerabha. Kungathuthukisa ubukhulu bendawo yerabha lapho isetshenziswa njenge-ejenti, ilungele ikakhulukazi irabha le-nitrile nerabha. Ingasetshenziswa futhi njenge-anti-mosquito uwoyela kanye nokuphindisela. Inomthelela ophendulayo ezinambuzaneni ezincelisayo ezifana nomiyane, amaSandflies, ama-courms kanye nezinsensane. Isikhathi sokuphinda esisebenzayo singamahora ama-2 kuya kwayi-4.
1. Kuyinto engabonakali emanzini okushisa kwamakamelo, incibilika kakhulu ezinhlafunweni ze-organic kanye nama-hydrocarbons, futhi inokuhambisana okuhle nama-resins amaningi wezimboni. UDimethyl phthalate uthambile. Lapho ibamba umlilo, sebenzisa amanzi, i-ejenti yokucima i-foam, isikhutha, i-ejenti yokucisha impuphu ukucisha umlilo.
2. Izakhiwo zamakhemikhali: kuyazinza umoya nokushisa, futhi akuboli lapho kufuthelwa amahora angama-50 eduze kwephuzu elibilayo. Lapho umphunga kaDimethyl phthalate udluliswa ngesithando esifudumele esingama-450 ° C Umkhiqizo ngamanzi angama-4,6%, ama-28.2% anhydride, futhi ama-51% angathathi hlangothi. Konke okunye okusemthethweni. Ngaphansi kwezimo ezifanayo, ama-36% ku-608 ° C, 97% ku-805 ° C, futhi u-100% ku-1000 ° C ane-pyrolysis.
I-3. Lapho uMaimethyl phthalate uhlotshiswe nge-methanol isixazululo se-caustic potassium ngo-30 ° C, 22.4% ngehora eli-1, namahora angama-45.8% emahoreni angama-8 ahlotshiswe nge-hydrolyzed.
I-4. Iphendula nge-Phenyl Magnesium Bromide ukukhiqiza i-10,10-dipheyylanthrone.
