| Amakhodi Engozi | 36/37/38 - Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. |
| Incazelo Yokuphepha | 24/25 - Gwema ukuthintana nesikhumba namehlo. |
Isingeniso
I-3,4-Dimethylbenzophenone, eyaziwa nangokuthi i-ketocarbonate noma i-Benzoin. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:
Imvelo:
-Ukubukeka: I-3,4-Dimethylbenzophenone i-crystalline solid solid.
-I-Solubility: Icishe ingancibiliki emanzini, futhi inokuncibilika okuphezulu kuma-organic solvents njenge-ethanol ne-dimethylformamide.
-Iphuzu elincibilikayo: Iphuzu lokuncibilika lika-3,4-dimethylbenzophenone lingaba ngu-132-134 degrees Celsius.
-Izakhiwo ze-Chemical: I-reagent ye-electrophilic engabamba iqhaza ekuphenduleni okuhlukahlukene okufana nokwakhiwa kwebhondi ye-hydrogen, ukusabela kokunciphisa i-oxidation phakathi kwe-ketone carbon ne-methyl.
Sebenzisa:
- I-3,4-Dimethyl benzophenone isetshenziswa ngokuyinhloko njenge-reagent ye-organic synthesis reactions.
-Ingasetshenziswa njenge-reagent ye-electrophilic ukuze ibambe iqhaza ekuphenduleni kwe-electrophilic, ukwakheka kwe-ketone carbonate nokunye ukusabela.
-Ingasetshenziswa futhi njenge-photosensitizer ye-lithography, ukuphulukisa ukukhanya nezinye izinkambu.
Indlela Yokulungiselela:
Enye indlela yokulungiswa kwe--3,4-dimethyl benzophenone ukusabela kokuhlanganiswa kwe-barone. Izinyathelo zokusabela zimi kanje: Okokuqala, i-styrene isabela nge-bromine eyeqile ngaphansi kokukhanya noma ukukhanya kwe-ultraviolet ukwenza i-β-bromostyrene. I-β-bromostyrene bese isabela nge-hydroxide (isb, i-NaOH) ukuze yakhe i-3,4-dimethylbenzophenone.
-Enye indlela yokulungiselela ukusabela i-acetophenone ne-sodium bromide ngaphansi kwezimo ze-alkaline ukukhiqiza i-3,4-dimethyl benzophenone.
Ulwazi Lokuphepha:
- 3,4-Dimethylbenzophenone inobuthi obuncane.
-Gwema ukuthintana kwesikhumba nokuhogela lapho usebenzisa.
-Ruyi ukuthintana kwangaphandle esikhumbeni, kufanele ngokushesha hashaza ngamanzi amaningi.
-Uma uhogelwe, phuthuma endaweni enomoya omuhle.
-Kunconywa ukugqoka amagilavu okuvikela afanelekile kanye nemishini yokuphefumula ngesikhathi sokusebenza.
-Uma usebenzisa futhi ugcina, sicela ulandele izinqubo zokusebenza eziphephile futhi ubeke endaweni lapho izingane zingakwazi ukufinyelela khona.
