Isingeniso
I-2-Ethyl-4-hydroxy-5-methyl-3(2H)-furanone, eyaziwa nangokuthi i-MEKHP, iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso semvelo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-MEKHP:
Ikhwalithi:
- I-MEKHP iwuketshezi olungenambala olunambitheka ekhethekile.
-
Sebenzisa:
- I-MEKHP ivame ukusetshenziswa njengesixazululi nesimaphakathi ezinhlobonhlobo zezinqubo zokuhlanganisa amakhemikhali nezinto eziphilayo.
- Ingasetshenziswa njengempahla eluhlaza ye-resin elaphayo, i-synthetic intermediate yodayi abafanelekile, nezibulala-zinambuzane.
Indlela:
- Indlela yokulungiselela ye-MEKHP itholakala ngokuyinhloko ukusabela kwe-Auff kwe-methylpyridone ne-ethylene.
- Ukusabela kwe-Aouf ukusabela kwe-metathesis lapho i-MEKHP itholwa khona ngokusabela okukhulu okujabulisayo phambi kwe-acetylene.
Ulwazi Lokuphepha:
- I-MEKHP iyacasula emehlweni nasesikhumbeni futhi kufanele igezwe ngamanzi amaningi ngokushesha ngemva kokuthintana.
- Kufanele kuqashelwe ukugwema ukuhogela umhwamuko futhi ugweme ukuthintana namalangabi avulekile namazinga okushisa aphezulu.
- I-MEKHP iyikhemikhali futhi kufanele ilandele izinqubo ezifanele zokusebenza futhi isetshenziselwe endaweni engenawo umoya.
- Uma usebenzisa futhi ugcina, sicela ulandele imithetho yokuphatha ngokuphephile futhi ulahle imfucuza ngendlela efanele.
