| Ubutyhefu | Yodwa kwioyile yamalahle kwaye isetyenziswa ekwenzeni i-coumarone-indene resin. Le resin isetyenziselwa iipende, iglue, njl. kwaye ivumelekile kwipakethe yokutya. Kuncinci okwaziwayo malunga nobutyhefu ye-benzofuran ebantwini kodwa ityhefu ebukhali kuvavanyo izilwanyana zibandakanya ukusilela kwesibindi kunye nezintso. Ubutyhefu obungapheliyo kwizilwanyana ibandakanya umonakalo kwisibindi, izintso, imiphunga kunye nesisu. Ulawulo lobomi bonke (ulawulo lomlomo) lubangele umhlaza kwi zombini iimpuku kunye neempuku. |
Intshayelelo
I-Oxyindene (C9H6O2) yi-organic compound equlathe iiringi ze-benzene kunye nezangqa zebenzofuran. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-oxyinden:
Umgangatho:
Imbonakalo: I-Oxyinden yikristale engenambala eqinileyo.
Ukunyibilika: I-Oxyinden inokunyibilika kwiintlobo ezininzi ze-solvents eziphilayo, kodwa ayinyibiliki emanzini.
Sebenzisa:
I-Oxindene inokusetyenziswa njenge-additive to photosensitizers kunye ne-polymer stabilizers.
Indlela:
I-Oxyindene inokulungiswa ngokuphendula kwe-oxidation ye-benzofuran kunye ne-benzofuranone. Inkqubo ethile yokulungiselela inokubandakanya amanyathelo anzima kwi-organic synthesis, efuna ngokubanzi ukusetyenziswa kwe-oxidant phantsi kweemeko ezifanelekileyo.
Ulwazi ngoKhuseleko:
I-Oxyindene ithathwa njengento ekhuselekileyo phantsi kweemeko eziqhelekileyo zokusetyenziswa, kodwa isafuna ukuthotyelwa kweenkqubo ezifanelekileyo zokusebenza kwibhubhoratri nakwimveliso yoshishino.
Xa uphethe i-oxyinden, izixhobo zokuzikhusela ezifanelekileyo ezinjengeeglavu zekhemikhali, iiglasi, kunye nempahla yokuzikhusela kufuneka zinxitywe.
Kuphephe ukudibana nesikhumba kunye namehlo, kwaye ugweme ukuphefumla okanye ukufunxa i-oxyinden.
I-oxyyindene kufuneka igcinwe kwisikhongozeli esingangeni moya kude nendawo yokutshisa kunye nee-oxidants.
