Diisooctyl phthalate CAS 27554-26-3
Kei te diisooctyl phthalate nga ahuatanga o te tinana me te matū o nga pūhui benzoate.Ko nga ahuatanga matū o tenei matū ko te nuinga o nga waahanga ester e rua i runga i te mowhiti benzene.Ka taea e ia te tauhohenga taapiri nucleophilic i raro i te mahi a nga reagents nucleophilic kaha penei i te reagent hōputu me te reagent organolith.Ko te wae hākawa i roto i te hanganga o te matū ka taea hoki te huri ki te roopu hydroxyl e rite ana i raro i te mahi a tetahi kaihoko whakaheke kaha.

Ka taea te whakamahi i te waikawa phthalic hei kaiwhakatikatika, hei whakatika i te chromatographic hau, hei kaihoko whakakaha, hei whakarewa me te whakahiato.He rite nga ahuatanga o te tinana me te matū a Diisooctyl ki te benzoate, a ka whakamahia te nuinga hei whakarewa pararopi me te plasticizer i roto i te ahumahi rauemi polymer i roto i te hanga matū.Ko te Plasticizer (plasticizer) he taapiri rauemi polymer, he mea taapiri ki te papanga polymer, me te kore e whakarereke i ona ahuatanga matū taketake, ka whakaiti i te rewa rewa, te pāmahana whakawhiti karaihe me te pa rapa, kia pai ake ai te mahi, me te whakapai ake i te ngawari o te hua me te tensile. āhuatanga o te matū.
I te nuinga o te waa ka whakakiia i roto i te 180kg / pahū, ka taea hoki te mahi mo te kete whakarite.
