Intshayelelo
I-3,4-Dimethoxypropiophenone (eyaziwa nangokuthi i-DMBA) i-organic compound. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, iindlela zokwenza kunye nolwazi lokhuseleko:
Umgangatho:
- Imbonakalo: I-3,4-dimethoxypropiophenone ilulwelo olungenambala okanye ikristale emhlophe.
- Ukunyibilika: Kunokunyibilika okuphezulu kwi-ethers, ii-alcohol kunye nezinyibilikisi eziphilayo.
- Uzinzo: Izinze kakhulu kodwa iyathanda ukubola kukukhanya kwelanga.
Sebenzisa:
- I-Chemical reagents: I-3,4-dimethoxypropiophenone ingasetyenziswa njenge-reagent kwi-organic synthesis kunye nophando lweekhemikhali.
Indlela:
Indlela yokulungiselela i-3,4-dimethoxyphenylacetone ngokuqhelekileyo isebenzisa i-styrene njengento ekrwada, ifumana i-oxidation reaction ukuze yenze i-hydroquinone, kwaye yazisa amaqela e-methoxy kwiindawo ze-3 kunye ne-4 nge-acylation reaction kunye ne-methanol reaction.
Ulwazi ngoKhuseleko:
-Ityhefu: Ayinatyhefu encinci ebantwini, kodwa kuseyimfuneko ukuthatha amanyathelo okhuseleko kwaye uphephe ukuphefumla, ulusu okanye ukudibana kwamehlo.
- Ukutsha: I-3,4-dimethoxypropiophenone inokutsha kwaye inokutshisa xa ibonakaliswe kumadangatye avulekileyo okanye amaqondo obushushu aphezulu.
- Impembelelo yokusingqongileyo: Inkunkuma nezisombululo kufuneka zilahlwe ngokufanelekileyo ukuthintela ungcoliseko lwendalo esingqongileyo.
- Ugcino: Kufuneka igcinwe kwindawo epholileyo, eyomileyo, nengena umoya kakuhle, kude nomlilo kunye nezinto ezinokutsha.
