| Ukuncibilika | Ihlangana namanzi, utshwala, ama-ether, ama-ketone, ama-ester, ama-hydrocarbon anephunga elimnandi, ama-halogenated hydrocarbons nezinye izinyibilikisi, kodwa azihlangani nezinga eliphezulu le-aliphatic hydrocarbon. |
Izici Zomkhiqizo:
1.Uketshezi olumhlophe noma oluphuzi kancane olubonisa ngale nephunga elimnandi.Incibilika emanzini;i-ethanol;I-ether ne-chloroform, njll., ayizinzile, ibolile lapho ihlangana ne-alkali noma i-distilled kungcindezi yomoya.Ayizinzile, iyabola lapho ihlangana ne-alkali noma i-distilled kungcindezi yomoya.
I-2.Umkhiqizo unobuthi obuphansi, ukugwinya umkhiqizo kuvinjelwe ngokuqinile, opharetha kufanele agqoke izinto zokuzivikela.
3.Izakhiwo zamakhemikhali: I-Diacetone alcohol iqukethe i-carbonyl ne-hydroxyl ku-molecule, nezakhi zamakhemikhali ze-ketone kanye notshwala obuphakeme.Ukubola kwenzeka uma ishiselwa ku-130°C noma ngaphezulu nge-alkali, ikhiqiza ama-molecule angu-2 e-acetone.Uma ishiswa nge-sulfuric acid noma ukulandelela amanani e-iodine, iqeda amanzi ukuze yakhe i-isopropylidene acetone.Ukusebenzisana ne-sodium hypobromite kukhiqiza i-2-hydroxyisovaleric acid.I-Catalytic hydrogenation ikhiqiza i-2-methyl-2,4-pentanediol.
4.Lo mkhiqizo ucasula amehlo, isikhumba kanye nolwelwesi lwamafinyila lomgudu wokuphefumula.Ingena emzimbeni ngemigudu yokuphefumula neyokugaya ukudla, ithinte isimiso sezinzwa futhi ilimaze isibindi nesisu.Ukuhogela umhwamuko omningi kungakha i-pulmonary edema ngisho ne-coma.Ukuchayeka isikhathi eside kungaholela ku-dermatitis.
5.Itholakala kugwayi wokubhaka, ugwayi onezimbambo ezimhlophe, ugwayi wezinongo kanye nentuthu kagwayi.
Isicelo somkhiqizo:
I-1.I-diacetone alcohol ingasetshenziswa njengesicoci sensimbi, isilondolozi sezinkuni, isilondolozi sefilimu yezithombe nezidakamizwa, i-antifreeze, i-solvent for hydraulic fluids, i-extractant kanye ne-fiber finishing agent.
2.I-Diacetone alcohol isetshenziswa kakhulu njengesinyibilikisi sikapende we-electrostatic spray, i-celluloid, i-nitrocellulose, amafutha, amafutha, ama-wax nama-resin.I-Diacetone alcohol iyisici esiphezulu sokubilisa se-organic.I-viscosity iphansi futhi umphumela wokushisa ku-viscosity mncane.Isetshenziswa njenge-solvent ne-stripper kapende yopende we-cellulose ester, uyinki wokuphrinta, upende we-synthetic resin njll.
3.Isetshenziswa kabanzi njenge-solvent yama-resin, opende be-electrostatic spray, i-celluloid, imicu ye-nitro, amafutha, amafutha kanye nama-wax.Ibuye isetshenziswe njengesicoci sensimbi, isilondolozi sezinkuni, isilondolozi sefilimu yezithombe nemithi, i-antifreeze, i-solvent kawoyela we-hydraulic, i-extractant kanye ne-fiber finishing agent.Futhi kuwuhlobo lwe-organic synthesis intermediates.
I-4.I-solvent ye-Cosmetic, ikakhulukazi esetshenziswa njenge-nail polish nezinye izimonyo ze-solvent ephezulu yokubilisa.Ivamise ukwakhiwa ngezincibilikisi zamaphuzu abilayo aphansi kanye nezincibilikisi zamaphuzu aphakathi abilayo zibe izincibilikisi ezixubile, ukuze kutholwe izinga elifanele lokuhwamuka kanye ne-viscosity.
Amanothi Okugcina Umkhiqizo:
1.Gcina endaweni epholile, nengena umoya.
2. Gcina kude nomlilo kanye nomthombo wokushisa, gwema ukukhanya kwelanga.
3.Gcina isitsha sivaliwe.
4.Ayigqwali ensimbi, futhi ingagcinwa ezitsheni zensimbi, zensimbi ethambile noma i-aluminium, kodwa inomphumela ogugulekayo ezinhlotsheni eziningi zamapulasitiki.
5.Gcina futhi uthuthe ngokuhlukaniswa nama-oxidising agents nama-acids.
I-6.Ibhakede le-iron noma ibhodlela lengilazi ligcwele izinto zokugqoka ibhokisi lezinkuni.
